-Subject: [PATCH 1/4] movebits: Add SMT_TERMINAL - a last resort region type
-
-Some memory regions are usable, but only as a last resort just before we
-hand over control to a kernel image. Add the necessary movebits
-infrastructure to use these regions when all other options have been
-exhausted.

-Subject: [PATCH 2/4] memscan: build a linked list of memory scanners
-
-By registering memory scanners at runtime we can support multiple memory
-scanner functions, which helps us to isolate them and keep things
-modular, only registering them for specific platform/derivative
-combinations. This is preparation for adding a memory scanner that is
-specific to PXELINUX on bios and understands when the memory region
-occupied by the PXE stack can be reused.

-Subject: [PATCH 3/4] PXELINUX: Add bios memscan function
-
-We can mark the memory region occupied by the PXE stack as SMT_TERMINAL
-provided that KeepPXE isn't set. Historically some very old
-non-relocatable kernel images (memtest86+) have a load address that
-falls within the PXE stack region, so we need to attempt to load into
-that region if at all possible.

-
-We don't need to individually add the PXE regions, we already have two
-symbols that denote the memory region that will be freed when calling

-When call isohybrid with option '-u', it overflows on a 32 bits host. It
-seeks to 512 bytes before the end of the image to install gpt header. If
-the size of image is larger than LONG_MAX, it overflows fseek() and
-cause error:

-isohybrid: image-x86-64-20140505110100.iso: seek error - 8: Invalid argument
-
-Replace fseek with fseeko to fix this issue.
