Subject: [PATCH 3/5] KVM: arm64: pkvm: Turn __kvm_hyp_init_cpu into an inner label
Date: Sat, 21 Mar 2026 21:24:17 +0000	[thread overview]
Message-ID: <20260321212419.2803972-4-maz@kernel.org> (raw)
In-Reply-To: <20260321212419.2803972-1-maz@kernel.org>

__kvm_hyp_init_cpu really is an internal label for kvm_hyp_cpu_entry
and kvm_hyp_cpu_resume.

Make it clear that this is what it is, and drop a pointless branch
in kvm_hyp_cpu_resume.
