Subject: [PATCH v2 01/10] x86: Remove arch_has_random, arch_has_random_seed
Date: Wed,  6 Nov 2019 15:12:59 +0100	[thread overview]
Message-ID: <20191106141308.30535-2-rth@twiddle.net> (raw)
In-Reply-To: <20191106141308.30535-1-rth@twiddle.net>

Use the expansion of these macros directly in arch_get_random_*.

These symbols are currently part of the generic archrandom.h
interface, but are currently unused and can be removed.
