Subject[PATCH 0/6] mm: audit find_vma() callers
Date
Ensure find_vma() callers do so with the mmap_sem held. 

I'm sure there are a few more places left to fix, but
this is a pretty good start. Following the call chain,
some users become all tangled up, but I believe these
fixes are correct. Furthermore, the bulk of the callers
of find_vma are in a lot of functions where it is well
known that the mmap_sem is taken way before, such as
get_unmapped_area() family.

Please note that none of the patches are tested.

Thanks!

blackfin/ptrace: call find_vma with the mmap_sem held
m68k: call find_vma with the mmap_sem held in sys_cacheflush()
mips: call find_vma with the mmap_sem held
arc: call find_vma with the mmap_sem held
drivers/misc/sgi-gru/grufault.c: call find_vma with the mmap_sem held
drm/exynos: call find_vma with the mmap_sem held
