Compiling recent 2.6.29-rc kernels for ARM gives me the following warning:

arch/arm/mm/mmu.c: In function 'sanity_check_meminfo':
arch/arm/mm/mmu.c:697: warning: comparison between pointer and integer

This is because commit 3fd9825c42c784a59b3b90bdf073f49d4bb42a8d
"[ARM] 5402/1: fix a case of wrap-around in sanity_check_meminfo()"
in 2.6.29-rc5-git4 added a comparison of a pointer with PAGE_OFFSET,
which is an integer.

Fixed by casting PAGE_OFFSET to void *.
