x86: memtest: remove 64-bit division
Using gcc 3.3.5 a "make allmodconfig" + "CONFIG_KVM=n"
triggers a build error:
arch/x86/mm/built-in.o(.init.text+0x43f7): In function `__change_page_attr':
arch/x86/mm/pageattr.c:114: undefined reference to `__udivdi3'
make: *** [.tmp_vmlinux1] Error 1
The culprit turned out to be a division in arch/x86/mm/memtest.c
For more info see this thread:
http://marc.info/?l=linux-kernel&m=124416232620683
The patch entirely removes the division that caused the build
error.
[ Impact: build fix with certain GCC versions ]
