Subject: [PATCH 5/7] MIPS: Add kernel_pref & user_pref helpers
Date: Mon, 15 Oct 2018 18:33:21 +0000	[thread overview]
Message-ID: <20181015183304.16782-6-paul.burton@mips.com> (raw)
In-Reply-To: <20181015183304.16782-1-paul.burton@mips.com>

Add kernel_pref & user_pref macros to asm/asm-eva.h, providing an
abstraction around EVA & non-EVA pref instructions consistent with the
existing macros we have for cache & load/store instructions.

Signed-off-by: Paul Burton <paul.burton@mips.com>
