Subject: [PATCH v7 09/11] KVM: arm64: Move sanitized copies of CPU features
Date: Fri,  8 Oct 2021 16:58:30 +0100	[thread overview]
Message-ID: <20211008155832.1415010-10-tabba@google.com> (raw)
In-Reply-To: <20211008155832.1415010-1-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.
