[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.
