[PATCH 0/6] Improvements for random.h/archrandom.h

During patch review for an addition of archrandom.h for arm64,
it was suggeted that the arch_random_get_* functions should be
marked __must_check. Which does sound like a good idea, since
the by-reference integer output may be uninitialized when the
boolean result is false.

In addition, I noticed a few other minor inconsistencies between
the different architectures: x86 defines some functional macros
outside CONFIG_ARCH_RANDOM, and powerpc isn't using bool.

Richard Henderson (6):
random: Mark CONFIG_ARCH_RANDOM functions __must_check
x86: Move arch_has_random* inside CONFIG_ARCH_RANDOM
x86: Mark archrandom.h functions __must_check
powerpc: Use bool in archrandom.h
powerpc: Mark archrandom.h functions __must_check
s390x: Mark archrandom.h functions __must_check
