What error do you hit ?

Perhaps REG_{OUT,IN} in arch/x86/include/asm/arch_hweight.h should be
renamed instead, as this is a generic header file that can be included
anywhere, while the REG_{OUT,IN} definitions are only used locally,
in the header file?
Even better, those REG_OUT/REG_IN should be undefined at the end of the header since only
used in the headers inline functions:
