SubjectRe: [PATCH] arch: all: include: asm: bitops: Use bool instead of int for all bit test functions
Hello all:

I have tried m68k and aarch64, they need include linux/types.h just like
another archs have done (e.g. arc). And then they can pass building for
the default config.

For alpha, it can pass building with my alpha cross compiler (gcc 5.0),
but for safety reason, we'd better let it include linux/types.h, too.

For openrisc, after check the code, I guess, it is the same reason. And
excuse me, I lost my openrisc cross compiler which I originally built,
so I do not give a test now, I can generate it, but really need time.

Thanks.
