Actually, can you wait a bit? Felix just reminded me that we have a
similar patch pending from Ben Hutchings:
https://patchwork.kernel.org/patch/10808203/
And it seems there are two instances of __sw_hweight8, at least in my
wireless-drivers-next tree:
drivers/net/wireless/mediatek/mt76/mac80211.c: int i, nstream = __sw_hweight8(dev->antenna_mask);
drivers/net/wireless/mediatek/mt76/mac80211.c: int n_chains = __sw_hweight8(dev->antenna_mask);
So we need to think what to do.
