Subject: [PATCH RFC v3 06/27] KVM: arm64: Pull ctxt_has_ helpers to start of sysreg-sr.h
Date: Fri, 20 Dec 2024 16:46:31 +0000 [thread overview]
Message-ID: <20241220-kvm-arm64-sme-v3-6-05b018c1ffeb@kernel.org> (raw)
In-Reply-To: <20241220-kvm-arm64-sme-v3-0-05b018c1ffeb@kernel.org>
Rather than add earlier prototypes of specific ctxt_has_ helpers let's just
pull all their definitions to the top of sysreg-sr.h so they're all
available to all the individual save/restore functions.
