[PATCH 0/2] x86: turn off wrongly enabled CONFIG_GENERIC_HWEIGHT

From: Masahiro Yamada

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
