  s390x: Mark archrandom.h functions __must_check (2020-01-25 12:18:51 -0500)

----------------------------------------------------------------
Change /dev/random so that it uses the CRNG and only blocking if the
CRNG hasn't initialized, instead of the old blocking pool.  Also clean
up archrandom.h, and some other miscellaneous cleanups.
