Subject: [PATCH] x86/boot/compressed/64: Drop the now-unused finalize_identity_maps()
Date: Fri, 13 Nov 2020 16:08:10 +0100	[thread overview]
Message-ID: <20201113150810.1233016-1-vkuznets@redhat.com> (raw)

Since commit 8570978ea030 ("x86/boot/compressed/64: Don't pre-map memory in
KASLR code") finalize_identity_maps() has no users, drop it.
