Subject: [PATCH v5 02/16] x86/mtrr: remove unused cyrix_set_all() function
Date: Wed, 2 Nov 2022 08:46:59 +0100 [thread overview]
Message-ID: <20221102074713.21493-3-jgross@suse.com> (raw)
In-Reply-To: <20221102074713.21493-1-jgross@suse.com>
The Cyrix CPU specific MTRR function cyrix_set_all() will never be
called, as the struct mtrr_ops set_all() callback will only be called
in the use_intel() case, which would require the use_intel_if member
of struct mtrr_ops to be set, which isn't the case for Cyrix.
Note that this patch has already been applied to tip.git.
