Linus Torvalds 8d4fbcfbe0 Fix WARN_ON() on bitfield ops ... Alexey Dobriyan noticed that the new WARN_ON() semantics that were introduced by commit 684f978347 (to also return the value to be warned on) didn't compile when given a bitfield, because the typeof doesn't work for bitfields. So instead of the typeof trick, use an "int" variable together with a "!!(x)" expression, as suggested by Al Viro. To make matters more interesting, Paul Mackerras points out that that is sub-optimal on Power, but the old asm-coded comparison seems to be buggy anyway on 32-bit Power if the conditional was 64-bit, so I think there are more problems there. Regardless, the new WARN_ON() semantics may have been a bad idea. But this at least avoids the more serious complications.
