-    i915: Add support for MSI and interrupt mitigation.
-    
-    Previous attempts at interrupt mitigation had been foiled by i915_wait_irq's
-    failure to update the sarea seqno value when the status page indicated that
-    the seqno had already been passed.  MSI support has been seen to cut CPU
-    costs by up to 40% in some workloads by avoiding other expensive interrupt
-    handlers for frequent graphics interrupts.

-commit 91c2ebb8e78aa64f4807399b506ec0090ae5f3d6
-Author: Matthew Garrett <mjg59@srcf.ucam.org>
-Date:   Tue Aug 5 19:37:25 2008 +0100
-
-    Add Intel ACPI IGD OpRegion support
-    
-    This adds the support necessary for allowing ACPI backlight control to
-    work on some newer Intel-based graphics systems. Tested on Thinkpad T61
-    and HP 2510p hardware.

-    separate i915 suspend/resume functions into their own file
-    
-    [Patch against drm-next.  Consider this a trial balloon for our new Linux
-    development model.]
-    
-    This is a big chunk of code.  Separating it out makes it easier to change
-    without churn on the main i915_drv.c file (and there will be churn as we
-    fix bugs and add things like kernel mode setting).  Also makes it easier
-    to share this file with BSD.

-    drm: Rework vblank-wait handling to allow interrupt reduction.
-    
-    Previously, drivers supporting vblank interrupt waits would run the interrupt
-    all the time, or all the time that any 3d client was running, preventing the
-    CPU from sleeping for long when the system was otherwise idle.  Now, interrupts
-    are disabled any time that no client is waiting on a vblank event. The new
-    method uses vblank counters on the chipsets when the interrupts are turned
-    off, rather than counting interrupts, so that we can continue to present
-    accurate vblank numbers.

-    Export shmem_file_setup for DRM-GEM
-    
-    GEM needs to create shmem files to back buffer objects.  Though currently
-    creation of files for objects could have been driven from userland, the
-    modesetting work will require allocation of buffer objects before userland
-    is running, for boot-time message display.

-Author: Eric Anholt <eric@anholt.net>
-Date:   Wed Jul 30 12:06:12 2008 -0700
-
-    drm: Add GEM ("graphics execution manager") to i915 driver.
-    
-    GEM allows the creation of persistent buffer objects accessible by the
-    graphics device through new ioctls for managing execution of commands on the
-    device.  The userland API is almost entirely driver-specific to ensure that
-    any driver building on this model can easily map the interface to individual
-    driver requirements.
-    
-    GEM is used by the 2d driver for managing its internal state allocations and
-    will be used for pixmap storage to reduce memory consumption and enable
-    zero-copy GLX_EXT_texture_from_pixmap, and in the 3d driver is used to enable
-    GL_EXT_framebuffer_object and GL_ARB_pixel_buffer_object.

-+/** @file drm_gem.c
-+ *
-+ * This file provides some of the base ioctls and library routines for
-+ * the graphics memory manager implemented by each device driver.
-+ *
-+ * Because various devices have different requirements in terms of
-+ * synchronization and migration strategies, implementing that is left up to
-+ * the driver, and all that the general API provides should be generic --
-+ * allocating objects, reading/writing data with the cpu, freeing objects.
-+ * Even there, platform-dependent optimizations for reading/writing data with
-+ * the CPU mean we'll likely hook those out to driver-specific calls.  However,
-+ * the DRI2 implementation wants to have at least allocate/mmap be generic.
-+ *
-+ * The goal was to have swap-backed object allocation managed through
-+ * struct file.  However, file descriptors as handles to a struct file have
-+ * two major failings:
-+ * - Process limits prevent more than 1024 or so being used at a time by
-+ *   default.
-+ * - Inability to allocate high fds will aggravate the X Server's select()
-+ *   handling, and likely that of many GL client applications as well.
-+ *
-+ * This led to a plan of using our own integer IDs (called handles, following
-+ * DRM terminology) to mimic fds, and implement the fd syscalls we need as
-+ * ioctls.  The objects themselves will still include the struct file so
-+ * that we can transition to fds if the required kernel infrastructure shows
-+ * up at a later date, and as our interface with shmfs for memory allocation.

-+ * and make sure they remain coherent. A few concrete examples may
-+ * help to explain how it works. For shorthand, we use the notation
-+ * (read_domains, write_domain), e.g. (CPU, CPU) to indicate the
-+ * a pair of read and write domain masks.
-+ *
-+ * Case 1: the batch buffer
-+ *

-+ *     3. Mapped to GTT
-+ *     4. Read by GPU
-+ *     5. Unmapped from GTT
-+ *     6. Freed
-+ *
-+ *     Let's take these a step at a time
-+ *
-+ *     1. Allocated
-+ *             Pages allocated from the kernel may still have
-+ *             cache contents, so we set them to (CPU, CPU) always.
-+ *     2. Written by CPU (using pwrite)
-+ *             The pwrite function calls set_domain (CPU, CPU) and
-+ *             this function does nothing (as nothing changes)
-+ *     3. Mapped by GTT
-+ *             This function asserts that the object is not
-+ *             currently in any GPU-based read or write domains
-+ *     4. Read by GPU
-+ *             i915_gem_execbuffer calls set_domain (COMMAND, 0).
-+ *             As write_domain is zero, this function adds in the
-+ *             current read domains (CPU+COMMAND, 0).
-+ *             flush_domains is set to CPU.
-+ *             invalidate_domains is set to COMMAND
-+ *             clflush is run to get data out of the CPU caches
-+ *             then i915_dev_set_domain calls i915_gem_flush to
-+ *             emit an MI_FLUSH and drm_agp_chipset_flush
-+ *     5. Unmapped from GTT
-+ *             i915_gem_object_unbind calls set_domain (CPU, CPU)
-+ *             flush_domains and invalidate_domains end up both zero
-+ *             so no flushing/invalidating happens
-+ *     6. Freed
-+ *             yay, done
-+ *
-+ * Case 2: The shared render buffer
-+ *
-+ *     1. Allocated
-+ *     2. Mapped to GTT
-+ *     3. Read/written by GPU
-+ *     4. set_domain to (CPU,CPU)
-+ *     5. Read/written by CPU
-+ *     6. Read/written by GPU
-+ *
-+ *     1. Allocated
-+ *             Same as last example, (CPU, CPU)
-+ *     2. Mapped to GTT
-+ *             Nothing changes (assertions find that it is not in the GPU)
-+ *     3. Read/written by GPU
-+ *             execbuffer calls set_domain (RENDER, RENDER)
-+ *             flush_domains gets CPU
-+ *             invalidate_domains gets GPU
-+ *             clflush (obj)
-+ *             MI_FLUSH and drm_agp_chipset_flush
-+ *     4. set_domain (CPU, CPU)
-+ *             flush_domains gets GPU
-+ *             invalidate_domains gets CPU
-+ *             wait_rendering (obj) to make sure all drawing is complete.
-+ *             This will include an MI_FLUSH to get the data from GPU
-+ *             to memory
-+ *             clflush (obj) to invalidate the CPU cache
-+ *             Another MI_FLUSH in i915_gem_flush (eliminate this somehow?)
-+ *     5. Read/written by CPU
-+ *             cache lines are loaded and dirtied
-+ *     6. Read written by GPU
-+ *             Same as last GPU access
-+ *
-+ * Case 3: The constant buffer

-+ *     1. Allocated
-+ *     2. Written by CPU

-+ *     4. Updated (written) by CPU again
-+ *     5. Read by GPU
-+ *
-+ *     1. Allocated
-+ *             (CPU, CPU)
-+ *     2. Written by CPU

-+ *
-+ * Support for managing tiling state of buffer objects.
-+ *
-+ * The idea behind tiling is to increase cache hit rates by rearranging
-+ * pixel data so that a group of pixel accesses are in the same cacheline.
-+ * Performance improvement from doing this on the back/depth buffer are on
-+ * the order of 30%.
-+ *
-+ * Intel architectures make this somewhat more complicated, though, by
-+ * adjustments made to addressing of data when the memory is in interleaved
-+ * mode (matched pairs of DIMMS) to improve memory bandwidth.
-+ * For interleaved memory, the CPU sends every sequential 64 bytes
-+ * to an alternate memory channel so it can get the bandwidth from both.
-+ *
-+ * The GPU also rearranges its accesses for increased bandwidth to interleaved
-+ * memory, and it matches what the CPU does for non-tiled.  However, when tiled
-+ * it does it a little differently, since one walks addresses not just in the
-+ * X direction but also Y.  So, along with alternating channels when bit
-+ * 6 of the address flips, it also alternates when other bits flip --  Bits 9
-+ * (every 512 bytes, an X tile scanline) and 10 (every two X tile scanlines)
-+ * are common to both the 915 and 965-class hardware.
-+ *
-+ * The CPU also sometimes XORs in higher bits as well, to improve
-+ * bandwidth doing strided access like we do so frequently in graphics.  This
-+ * is called "Channel XOR Randomization" in the MCH documentation.  The result
-+ * is that the CPU is XORing in either bit 11 or bit 17 to bit 6 of its address
-+ * decode.
-+ *
-+ * All of this bit 6 XORing has an effect on our memory management,
-+ * as we need to make sure that the 3d driver can correctly address object
-+ * contents.
-+ *
-+ * If we don't have interleaved memory, all tiling is safe and no swizzling is
-+ * required.
-+ *
-+ * When bit 17 is XORed in, we simply refuse to tile at all.  Bit
-+ * 17 is not just a page offset, so as we page an objet out and back in,
-+ * individual pages in it will have different bit 17 addresses, resulting in
-+ * each 64 bytes being swapped with its neighbor!
-+ *
-+ * Otherwise, if interleaved, we have to tell the 3d driver what the address
-+ * swizzling it needs to do is, since it's writing with the CPU to the pages
-+ * (bit 6 and potentially bit 11 XORed in), and the GPU is reading from the
-+ * pages (bit 6, 9, and 10 XORed in), resulting in a cumulative bit swizzling
-+ * required by the CPU of XORing in bit 6, 9, 10, and potentially 11, in order
-+ * to match what the GPU expects.

-    i915: Use struct_mutex to protect ring in GEM mode.
-    
-    In the conversion for GEM, we had stopped using the hardware lock to protect
-    ring usage, since it was all internal to the DRM now.  However, some paths
-    weren't converted to using struct_mutex to prevent multiple threads from
-    concurrently working on the ring, in particular between the vblank swap handler

-Subject: [PATCH] fastboot: create a "asynchronous" initlevel
-
-This patch creates an asynchronous initlevel (6a) which is at the same
-level as the normal device initcalls, but with the difference that they
-are run asynchronous from all the other initcalls. The purpose of this
-*selective* level is that we can move long waiting inits that are not
-boot-critical to this level one at a time.
-
-To keep things not totally insane, the asynchronous initcalls are async
-to the other initcalls, but are still ordered to themselves; think of it
-as "bottom-half-not-softirq". This has the benefit that async drivers
-still have stable device ordering between them.

-Subject: [PATCH] fastboot: turn the USB hostcontroller initcalls into async initcalls
-
-the USB host controller init calls take a long time, mostly due to a
-"minimally 100 msec" delay *per port* during initialization.
-These are prime candidates for going in parallel to everything else.
-
-The USB device ordering is not affected by this due to the
-serialized-within-eachother property of async initcalls.

-While this reduces parallelism a little, it does provide
-lock-for-lock compatibility. The hit to prallelism isn't too
-bad, most of the init calls are done immediately or actually
-block for their delays.

-Subject: [PATCH] fastboot: sync the async execution before late_initcall and move level 6s (sync) first
-
-Rene Herman points out several cases where it's basically needed to have
-all level 6/6a/6s calls done before the level 7 (late_initcall) code
-runs. This patch adds a sync point in the transition from the 6's to the
-7's.
-
-Second, this patch makes sure that level 6s (sync) happens before the
-async code starts, and puts a user in driver/pci in this category that
-needs to happen before device init.

-
-In preparation for relaxing the first delay, this patch adds a retry
-attempt in case /sbin/init is not found. Before retrying, the code
-will wait for all device init to complete.
-
-While this patch by itself doesn't gain boot time yet (it needs follow on
-patches), the alternative already is to panic()...

-Subject: [PATCH] fastboot: remove "wait for all devices before mounting root" delay
-
-In the non-initrd case, we wait for all devices to finish their
-probing before we try to mount the rootfs.
-In practice, this means that we end up waiting 2 extra seconds for
-the PS/2 mouse probing even though the root holding device has been
-ready since a long time.
-
-The previous two patches in this series made the RAID autodetect code
-do it's own "wait for probing to be done" code, and added
-"wait and retry" functionality in case the root device isn't actually
-available.
-
-These two changes should make it safe to remove the delay itself,
-and this patch does this. On my test laptop, this reduces the boot time
-by 2 seconds (kernel time goes from 3.9 to 1.9 seconds).

-Subject: [PATCH] fastboot: make the RAID autostart code print a message just before waiting
-
-As requested/suggested by Neil Brown: make the raid code print that it's
-about to wait for probing to be done as well as give a suggestion on how
-to disable the probing if the user doesn't use raid.

-Subject: [PATCH] fastboot: remove duplicate unpack_to_rootfs()
-
-we check if initrd is initramfs first and then do real unpack. The
-check isn't required, we can directly do unpack. If initrd isn't
-initramfs, we can remove garbage. In my laptop, this saves 0.1s boot
-time. This penalizes non-initramfs case, but now initramfs is mostly
-widely used.

-Subject: [PATCH] Add a script to visualize the kernel boot process / time
-
-When optimizing the kernel boot time, it's very valuable to visualize
-what is going on at which time. In addition, with the fastboot asynchronous
-initcall level, it's very valuable to see which initcall gets run where
-and when.
-
-This patch adds a script to turn a dmesg into a SVG graph (that can be
-shown with tools such as InkScape, Gimp or Firefox) and a small change
-to the initcall code to print the PID of the thread calling the initcall
-(so that the script can work out the parallelism).

-Subject: [PATCH] fastboot: fix issues and improve output of bootgraph.pl
-
-David Sanders reported some issues with bootgraph.pl's display
-of his sytems bootup; this commit fixes these by scaling the graph
-not from 0 - end time but from the first initcall to the end time;
-the minimum display size etc also now need to scale with this, as does
-the axis display.

-Subject: [PATCH] r8169: add hw start helpers for the 8168 and the 8101
-
-This commit triggers three 'defined but not used' warnings but
-I prefer avoiding to tie these helpers to a specific change in
-the hw start sequences of the 8168 or of the 8101.

-The following patch adds support for Intel's 945GME graphics chip to
-the intelfb driver.  I have assumed that the 945GME is identical to the
-already-supported 945GM apart from its PCI IDs; this is based on a quick
-look at the X driver for these chips which seems to treat them
-identically.

-The 945GME is used in the ASUS Eee 901, and I coded this in the hope that 
-I'd be able to use it to get a console at the native 1024x600 resolution 
-which is not known to the BIOS.  I realised too late that the intelfb 
-driver does not support mode changing on laptops, so it won't be any 
-use for me.  But rather than throw it away I will post it here as 
-essentially "untested"; maybe someone who knows more about this driver, 
-and with more useful hardware to test on, can pick it up.

-+ * Locking may look a bit complicated but isn't really:
-+ *
-+ * The buffer usage atomic_t needs to be protected by dev->struct_mutex
-+ * when there is a chance that it can be zero before or after the operation.
-+ *
-+ * dev->struct_mutex also protects all lists and list heads,
-+ * Hash tables and hash heads.
-+ *
-+ * bo->mutex protects the buffer object itself excluding the usage field.
-+ * bo->mutex does also protect the buffer list heads, so to manipulate those,
-+ * we need both the bo->mutex and the dev->struct_mutex.
-+ *
-+ * Locking order is bo->mutex, dev->struct_mutex. Therefore list traversal
-+ * is a bit complicated. When dev->struct_mutex is released to grab bo->mutex,
-+ * the list traversal will, in general, need to be restarted.

-+ * This file implements a simple replacement for the buffer manager use
-+ * of the heavyweight hardware lock.
-+ * The lock is a read-write lock. Taking it in read mode is fast, and
-+ * intended for in-kernel use only.
-+ * Taking it in write mode is slow.
-+ *
-+ * The write mode is used only when there is a need to block all
-+ * user-space processes from allocating a
-+ * new memory area.
-+ * Typical use in write mode is X server VT switching, and it's allowed
-+ * to leave kernel space with the write lock held. If a user-space process
-+ * dies while having the write-lock, it will be released during the file
-+ * descriptor release.
-+ *
-+ * The read lock is typically placed at the start of an IOCTL- or
-+ * user-space callable function that may end up allocating a memory area.
-+ * This includes setstatus, super-ioctls and no_pfn; the latter may move
-+ * unmappable regions to mappable. It's a bug to leave kernel space with the
-+ * read lock held.
-+ *
-+ * Both read- and write lock taking is interruptible for low signal-delivery
-+ * latency. The locking functions will return -EAGAIN if interrupted by a
-+ * signal.
-+ *
-+ * Locking order: The lock should be taken BEFORE any kernel mutexes
-+ * or spinlocks.

-+ * This file implements a simple replacement for the buffer manager use
-+ * of the heavyweight hardware lock.
-+ * The lock is a read-write lock. Taking it in read mode is fast, and
-+ * intended for in-kernel use only.
-+ * Taking it in write mode is slow.
-+ *
-+ * The write mode is used only when there is a need to block all
-+ * user-space processes from allocating a
-+ * new memory area.
-+ * Typical use in write mode is X server VT switching, and it's allowed
-+ * to leave kernel space with the write lock held. If a user-space process
-+ * dies while having the write-lock, it will be released during the file
-+ * descriptor release.
-+ *
-+ * The read lock is typically placed at the start of an IOCTL- or
-+ * user-space callable function that may end up allocating a memory area.
-+ * This includes setstatus, super-ioctls and no_pfn; the latter may move
-+ * unmappable regions to mappable. It's a bug to leave kernel space with the
-+ * read lock held.
-+ *
-+ * Both read- and write lock taking is interruptible for low signal-delivery
-+ * latency. The locking functions will return -EAGAIN if interrupted by a
-+ * signal.
-+ *
-+ * Locking order: The lock should be taken BEFORE any kernel mutexes
-+ * or spinlocks.

+Subject: [PATCH] e100: add support for 82552 10/100 adapter
+
+This patch enables support for the new Intel 82552 adapter (new PHY paired
+with the existing MAC in the ICH7 chipset).  No new features are added to
+the driver, however there are minor changes due to updated registers and a
+few workarounds for hardware errata.

+Subject: [PATCH] ide/net: flip the order of SATA and network init
+
+this patch flips the order in which sata and network drivers are initialized.
+
+SATA probing takes quite a bit of time, and with the asynchronous infrastructure
+other drivers that run after it can execute in parallel. Network drivers do tend
+to take some real time talking to the hardware, so running these later is
+a good thing (the sata probe then runs concurrent)
+
+This saves about 15% of my kernels boot time.

+Subject: [PATCH] input: introduce a tougher i8042.reset
+
+Some bad touchpads don't reset right the first time (MSI Wind U-100 for
+example). This patch will retry the reset up to 5 times.
+
+In addition, this patch also adds a module parameter to not treat
+reset failures as fatal to the usage of the device. This prevents
+a touchpad failure from also disabling the keyboard....

++ * used to avoid destruction while the buffer object is still on a list.
++ * Lru lists may keep one refcount, the delayed delete list, and kref != 0
++ * keeps one refcount. When this refcount reaches zero,
++ * the object is destroyed.
++ * @proposed_flags: Proposed placement for the buffer. Changed only by the

++ * changed by the implementation prior to a buffer move if it wants to outsmart
++ * the buffer creator / user. This latter happens, for example, at eviction.
++ * @buffer_start: The virtual user-space start address of ttm_bo_type_user
++ * buffers.
++ * @type: The bo type.
++ * @offset: The current GPU offset, which can have different meanings
++ * depending on the memory type. For SYSTEM type memory, it should be 0.
++ * @mem: structure describing current placement.
++ * @val_seq: Sequence of the validation holding the @reserved lock.
++ * Used to avoid starvation when many processes compete to validate the
++ * buffer. This member is protected by the bo_device::lru_lock.
++ * @seq_valid: The value of @val_seq is valid. This value is protected by
++ * the bo_device::lru_lock.
++ * @lru: List head for the lru list.
++ * @ddestroy: List head for the delayed destroy list.
++ * @swap: List head for swap LRU list.
++ * @persistant_swap_storage: Usually the swap storage is deleted for buffers
++ * pinned in physical memory. If this behaviour is not desired, this member
++ * holds a pointer to a persistant shmem object.
++ * @destroy: Destruction function. If NULL, kfree is used.
++ * @sync_obj_arg: Opaque argument to synchronization object function.
++ * @sync_obj: Pointer to a synchronization object.
++ * @priv_flags: Flags describing buffer object internal state.
++ * @event_queue: Queue for processes waiting on buffer object status change.
++ * @mutex: Lock protecting all members with the exception of constant members
++ * and list heads. We should really use a spinlock here.
++ * @num_pages: Actual number of pages.
++ * @ttm: TTM structure holding system pages.
++ * @vm_hash: Hash item for fast address space lookup. Need to change to a
++ * rb-tree node.
++ * @vm_node: Address space manager node.
++ * @addr_space_offset: Address space offset.
++ * @cpu_writes: For synchronization. Number of cpu writers.
++ * @reserved: Deadlock-free lock used for synchronization state transitions.
++ * @acc_size: Accounted size for this object.
++ *
++ * Base class for TTM buffer object, that deals with data placement and CPU
++ * mappings. GPU mappings are really up to the driver, but for simpler GPUs
++ * the driver can usually use the placement offset @offset directly as the
++ * GPU virtual address. For drivers implementing multiple
++ * GPU memory manager contexts, the driver should manage the address space
++ * in these contexts separately and use these objects to get the correct
++ * placement and caching for these GPU maps. This makes it possible to use
++ * these objects for even quite elaborate memory management schemes.
++ * The destroy member, the API visibility of this object makes it possible
++ * to derive driver specific types.

++ * Locks a buffer object for validation. (Or prevents other processes from
++ * locking it for validation) and removes it from lru lists, while taking
++ * a number of measures to prevent deadlocks.
++ *
++ * Deadlocks may occur when two processes try to reserve multiple buffers in
++ * different order, either by will or as a result of a buffer being evicted
++ * to make room for a buffer already reserved. (Buffers are reserved before
++ * they are evicted). The following algorithm prevents such deadlocks from
++ * occuring:
++ * 1) Buffers are reserved with the lru spinlock held. Upon successful
++ * reservation they are removed from the lru list. This stops a reserved buffer
++ * from being evicted. However the lru spinlock is released between the time
++ * a buffer is selected for eviction and the time it is reserved.
++ * Therefore a check is made when a buffer is reserved for eviction, that it
++ * is still the first buffer in the lru list, before it is removed from the
++ * list. @check_lru == 1 forces this check. If it fails, the function returns
++ * -EINVAL, and the caller should then choose a new buffer to evict and repeat
++ * the procedure.
++ * 2) Processes attempting to reserve multiple buffers other than for eviction,
++ * (typically execbuf), should first obtain a unique 32-bit
++ * validation sequence number,
++ * and call this function with @use_sequence == 1 and @sequence == the unique
++ * sequence number. If upon call of this function, the buffer object is already
++ * reserved, the validation sequence is checked against the validation
++ * sequence of the process currently reserving the buffer,
++ * and if the current validation sequence is greater than that of the process
++ * holding the reservation, the function returns -EAGAIN. Otherwise it sleeps
++ * waiting for the buffer to become unreserved, after which it retries reserving.
++ * The caller should, when receiving an -EAGAIN error
++ * release all its buffer reservations, wait for @bo to become unreserved, and
++ * then rerun the validation with the same validation sequence. This procedure
++ * will always guarantee that the process with the lowest validation sequence
++ * will eventually succeed, preventing both deadlocks and starvation.
++ *
++ * Returns:
++ * -EAGAIN: The reservation may cause a deadlock. Release all buffer reservations,
++ * wait for @bo to become unreserved and try again. (only if use_sequence == 1).
++ * -ERESTART: A wait for the buffer to become unreserved was interrupted by
++ * a signal. Release all buffer reservations and return to user-space.

++/** @file ttm_lock.h
++ * This file implements a simple replacement for the buffer manager use
++ * of the DRM heavyweight hardware lock.
++ * The lock is a read-write lock. Taking it in read mode is fast, and
++ * intended for in-kernel use only.
++ * Taking it in write mode is slow.
++ *
++ * The write mode is used only when there is a need to block all
++ * user-space processes from validating buffers.
++ * It's allowed to leave kernel space with the write lock held.
++ * If a user-space process dies while having the write-lock,
++ * it will be released during the file descriptor release.
++ *
++ * The read lock is typically placed at the start of an IOCTL- or
++ * user-space callable function that may end up allocating a memory area.
++ * This includes setstatus, super-ioctls and faults; the latter may move
++ * unmappable regions to mappable. It's a bug to leave kernel space with the
++ * read lock held.
++ *
++ * Both read- and write lock taking is interruptible for low signal-delivery
++ * latency. The locking functions will return -ERESTART if interrupted by a
++ * signal.
++ *
++ * Locking order: The lock should be taken BEFORE any TTM mutexes
++ * or spinlocks.
++ *
++ * Typical usages:
++ * a) VT-switching, when we want to clean VRAM and perhaps AGP. The lock
++ * stops it from being repopulated.
++ * b) out-of-VRAM or out-of-aperture space, in which case the process
++ * receiving the out-of-space notification may take the lock in write mode
++ * and evict all buffers prior to start validating its own buffers.

+    async: Fix module loading async-work regression
+    
+    Several drivers use asynchronous work to do device discovery, and we
+    synchronize with them in the compiled-in case before we actually try to
+    mount root filesystems etc.
+    
+    However, when compiled as modules, that synchronization is missing - the
+    module loading completes, but the driver hasn't actually finished
+    probing for devices, and that means that any user mode that expects to
+    use the devices after the 'insmod' is now potentially broken.
+    
+    We already saw one case of a similar issue in the ACPI battery code,
+    where the kernel itself expected the module to be all done, and unmapped
+    the init memory - but the async device discovery was still running.
+    That got hacked around by just removing the "__init" (see commit
+    5d38258ec026921a7b266f4047ebeaa75db358e5 "ACPI battery: fix async boot
+    oops"), but the real fix is to just make the module loading wait for all
+    async work to be completed.
+    
+    It will slow down module loading, but since common devices should be
+    built in anyway, and since the bug is really annoying and hard to handle
+    from user space (and caused several S3 resume regressions), the simple
+    fix to wait is the right one.
+    
+    This fixes at least
+    
+        http://bugzilla.kernel.org/show_bug.cgi?id=13063
+    
+    but probably a few other bugzilla entries too (12936, for example), and
+    is confirmed to fix Rafael's storage driver breakage after resume bug
+    report (no bugzilla entry).
+    
+    We should also be able to now revert that ACPI battery fix.

+
+OK, updated patch follows, with a changelog.
+
+I've added this check to user.c too, because that code can be called
+independently of the one in disk.c .  Also, if resume is user space-driven,
+it's a good idea to wait for all of the device probes to complete before
+continuing.
+
+Thanks,
+Rafael

+Subject: PM/Hibernate: Wait for SCSI devices scan to complete during resume
+
+There is a race between resume from hibernation and the asynchronous
+scanning of SCSI devices and to prevent it from happening we need to
+call scsi_complete_async_scans() during resume from hibernation.
+
+In addition, if the resume from hibernation is userland-driven, it's
+better to wait for all device probes in the kernel to complete before
+attempting to open the resume device.
