That's what I thought initially too but that won't fly because the lib/hweight.c helpers have to be inlined into arch/x86/lib/hweight.c so that gcc can take care of the clobbered registers. Otherwise, it just a "call __sw_hweightXX" that gets issued into asm. -- Regards/Gruss, Boris. - Advanced Micro Devices, Inc.
