Subject: [PATCH AUTOSEL 5.18 04/54] x86/cpufeatures: Move RETPOLINE flags to word 11
Date: Tue, 19 Jul 2022 21:09:41 -0400 [thread overview]
Message-ID: <20220720011031.1023305-4-sashal@kernel.org> (raw)
In-Reply-To: <20220720011031.1023305-1-sashal@kernel.org>
From: Peter Zijlstra <peterz@infradead.org>
[ Upstream commit a883d624aed463c84c22596006e5a96f5b44db31 ]
In order to extend the RETPOLINE features to 4, move them to word 11
where there is still room. This mostly keeps DISABLE_RETPOLINE
simple.
