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.
