Subject: forbid asm/bitops.h direct inclusion

forbid asm/bitops.h direct inclusion

Because of compile errors that may occur after bit changes if asm/bitops.h is
included directly without e.g.  linux/kernel.h which includes linux/bitops.h,
forbid direct inclusion of asm/bitops.h.  Thanks to Adrian Bunk.
