Subject: [PATCH v2 2/3] KVM: Move page mapping/unmapping APIs in kvm_host.h
Date: Tue, 7 Apr 2026 17:11:29 -0700 [thread overview]
Message-ID: <20260408001137.3290444-3-peter.fang@intel.com> (raw)
In-Reply-To: <20260408001137.3290444-1-peter.fang@intel.com>
Move kvm_vcpu_map*() and kvm_vcpu_unmap() so that a subsequent refactor
can use gpa_to_gfn() without a forward declaration.
No functional change intended.
