Hi Andrew,
After merging the akpm-current tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:
mm/built-in.o: In function `handle_mm_fault':
frame_vector.c:(.text+0x29628): undefined reference to
`do_huge_pmd_anonymous_page'
(Ignore the "frame_vector.c" above it is obviously incorrect.)
Probably caused by commit
747220c26dd0 ("huge tmpfs: add shmem_pmd_fault()")
[Andrew: I added this patch from Hugh today ... see other emails]
The condition protecting the call to do_huge_pmd_anonymous_page()
in __handle_mm_fault() has becom more complicated and so the call
has presumably no longer been removed by the compiler for the
!CONFIG_TRANSPARENT_HUGEPAGE case.
I have reverted that commit for today.
