Subject: [PATCH v2 04/10] linux/random.h: Remove arch_has_random, arch_has_random_seed
Date: Wed,  6 Nov 2019 15:13:02 +0100
Message-ID: <20191106141308.30535-5-rth@twiddle.net> (raw)
In-Reply-To: <20191106141308.30535-1-rth@twiddle.net>

The arm64 version of archrandom.h will need to be able to test for
support and read the random number without preemption, so a separate
query predicate is not practical.

Since this part of the generic interface is unused, remove it.
