- Everything in include/cpu/generic/x86/arch/* goes into include/arch/x86 now. - include/cpu/generic/x86/div64.h moves into include/arch/x86, too. - The former include/cpu/generic/x86/arch/elf.h moved to include/arch/x86/archelf.h, as elf.h already exists in include/ and we must prevent a name clash.
