Subject: [PATCH v1 2/6] KVM: arm64: Add bit masks for HAFGRTR_EL2
Date: Tue, 5 Dec 2023 10:22:44 +0000 [thread overview]
Message-ID: <20231205102248.1915895-3-tabba@google.com> (raw)
In-Reply-To: <20231205102248.1915895-1-tabba@google.com>
The HAFGRTR_EL2 register isn't used yet, but it will be in future
patches. It's also the only FGT register remaining (not including
FGT2 registers).
Add the masks for completeness and future patches. The definition
is from the latest Arm Architecture System Registers xml
specification [*].
