Well, the driver could do:
drivers/net/wireless/mediatek/mt76/Kconfig:
+ select GENERIC_HWEIGHT
but maybe arch/ix64/Kconfig (where the build error is) could be asked to do:
config GENERIC_HWEIGHT
def_bool y
like 23 other $arch-es do. Aha, ia64 provides inline functions via some
a twisty maze of header files.
Tony, Fengguang, what header(s) should be used to reach __arch_hweight8()?
thanks,
