__sw_hweight8() is just internal implementation.

Drivers should use the common API, hweight8().

This patch should go to x86 tree along with 2/2.

Otherwise, all{yes,mod}config of x86 would be broken.

This patch is trivial enough.
I want ACK from the net/wireless maintainer
so that this can go in via x86 tree.

Sounds good to me, feel free to push via the x86 tree.

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.
