Subject: [PATCH v2 10/13] KVM: arm64: Move sanitized copies of CPU features
Date: Tue, 15 Jun 2021 14:39:47 +0100	[thread overview]
Message-ID: <20210615133950.693489-11-tabba@google.com> (raw)
In-Reply-To: <20210615133950.693489-1-tabba@google.com>

Move the sanitized copies of the CPU feature registers to the
recently created sys_regs.c. This consolidates all copies in a
more relevant file.

No functional change intended.
