Subject: [PATCH v2 80/94] KVM: arm64: Use accessors for timer ctl/cval/offset
Date: Tue, 11 Feb 2020 17:49:24 +0000
Message-ID: <20200211174938.27809-81-maz@kernel.org> (raw)
In-Reply-To: <20200211174938.27809-1-maz@kernel.org>

Instead of directly accessing the various fields in the timer data
structures, add accessors that provide the same service. By making the
weak, we'll be able to override them in a subsequent patch, making it
possible to move them in the VNCR page, as they will be directly
accessed by the guest.
