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. -- Kalle Valo
