Subject: [PATCH] arch/tile: Rename the hweight() implementations to __arch_hweight().
See commit 1527bc8b928dd1399c3d3467dd47d9ede210978a.

Mike, thanks for the pointer to the hweight issue. Since we are using
__builtin_popcount() and the compiler can do constant propagation, etc.,
with it at compile-time, this is less critical, but it seems like the
easiest way to get the definitions of the HWEIGHT macros.
