x86 should not enable CONFIG_GENERIC_HWEIGHT because lib/hweight.c is not used by x86.
The only user is drivers/net/wireless/mediatek/mt76/mac80211.c
Of course, this driver is wrong since drivers should use the generic API, hweight8().
After fixing it, x86 does not need to compile lib/hweight.c at all.
The real implementation is located in arch/x86/lib/hweight.S
Masahiro Yamada (2): wireless: mt76: call hweight8() instead of __sw_hweight8() x86: disable CONFIG_GENERIC_HWEIGHT and remove __HAVE_ARCH_SW_HWEIGHT
