Subject: [PATCH v1 12/44] KVM: arm64: Move pstate reset value definitions to kvm_arm.h
Date: Wed, 27 Mar 2024 17:34:59 +0000	[thread overview]
Message-ID: <20240327173531.1379685-13-tabba@google.com> (raw)
In-Reply-To: <20240327173531.1379685-1-tabba@google.com>

Move the macro defines of the pstate reset values to a shared
header to be used by hyp in future patches.

No functional change intended.
