Subject: [PATCH v2 20/24] KVM: x86/mmu: Export kvm_tdp_map_page()
Date: Tue, 12 Nov 2024 15:38:27 +0800	[thread overview]
Message-ID: <20241112073827.22270-1-yan.y.zhao@intel.com> (raw)
In-Reply-To: <20241112073327.21979-1-yan.y.zhao@intel.com>

From: Rick Edgecombe <rick.p.edgecombe@intel.com>

In future changes coco specific code will need to call kvm_tdp_map_page()
from within their respective gmem_post_populate() callbacks. Export it
so this can be done from vendor specific code. Since kvm_mmu_reload()
will be needed for this operation, export its callee kvm_mmu_load() as
well.
