Revert "lttng-modules: add bbappend"
lttng-modules v2.10.10 release with fixes is available now and recipe has been upgraded in OE-Core. So bbappend no longer required. This reverts commit 886d2063cd54069f831239febf2be118ab774d01.

12 mm: create the new vm_fault_t type
13
14 Page fault handlers are supposed to return VM_FAULT codes, but some
15 drivers/file systems mistakenly return error numbers. Now that all
16 drivers/file systems have been converted to use the vm_fault_t return
17 type, change the type definition to no longer be compatible with 'int'.
18 By making it an unsigned int, the function prototype becomes
19 incompatible with a function which returns int. Sparse will detect any
20 attempts to return a value which is not a VM_FAULT code.
21
22 VM_FAULT_SET_HINDEX and VM_FAULT_GET_HINDEX values are changed to avoid
23 conflict with other VM_FAULT codes.

15 None of synchronize_rcu_bh, synchronize_rcu_bh_expedited, call_rcu_bh,
16 rcu_barrier_bh, synchronize_sched, synchronize_sched_expedited,
17 call_rcu_sched, rcu_barrier_sched, get_state_synchronize_sched, and
18 cond_synchronize_sched are actually used. This commit therefore removes
19 their trivial wrapper-function definitions.

12 pipe: stop using ->can_merge
13
14 Al Viro pointed out that since there is only one pipe buffer type to which
15 new data can be appended, it isn't necessary to have a ->can_merge field in
16 struct pipe_buf_operations, we can just check for a magic type.

11 syscalls: Remove start and number from syscall_get_arguments() args
12
13 At Linux Plumbers, Andy Lutomirski approached me and pointed out that the
14 function call syscall_get_arguments() implemented in x86 was horribly
15 written and not optimized for the standard case of passing in 0 and 6 for
16 the starting index and the number of system calls to get. When looking at
17 all the users of this function, I discovered that all instances pass in only
18 0 and 6 for these arguments. Instead of having this function handle
19 different cases that are never used, simply rewrite it to return the first 6
20 arguments of a system call.
21
22 This should help out the performance of tracing system calls by ptrace,
23 ftrace and perf.
