Subject: [PATCH v2 72/94] KVM: arm64: sysreg: Use ctxt_sys_reg() instead of raw sys_regs access
Date: Tue, 11 Feb 2020 17:49:16 +0000 [thread overview]
Message-ID: <20200211174938.27809-73-maz@kernel.org> (raw)
In-Reply-To: <20200211174938.27809-1-maz@kernel.org>
Now that we have a wrapper for the sysreg accesses, let's use that
consistently.

Subject: [PATCH v2 72/94] KVM: arm64: sysreg: Use ctxt_sys_reg() instead of raw sys_regs access
Date: Tue, 11 Feb 2020 17:49:16 +0000 [thread overview]
Message-ID: <20200211174938.27809-73-maz@kernel.org> (raw)
In-Reply-To: <20200211174938.27809-1-maz@kernel.org>
Now that we have a wrapper for the sysreg accesses, let's use that
consistently.

Subject: [PATCH v2 72/94] KVM: arm64: sysreg: Use ctxt_sys_reg() instead of raw sys_regs access
Date: Tue, 11 Feb 2020 17:49:16 +0000 [thread overview]
Message-ID: <20200211174938.27809-73-maz@kernel.org> (raw)
In-Reply-To: <20200211174938.27809-1-maz@kernel.org>
Now that we have a wrapper for the sysreg accesses, let's use that
consistently.
