commit 568c5fe5a54f2654f5a4c599c45b8a62ed9a2013 upstream.
Certain architectures may have the kernel image mapped separately to alias the linear map. Introduce a macro lm_alias to translate a kernel image symbol into its linear alias. This is used in part with work to add CONFIG_DEBUG_VIRTUAL support for arm64.
I think this commit was backported in 4.9 because one of the commits you dropped (6840bdd73d07 arm64: KVM: Use per-CPU vector when BP hardening is enabled) depended on it. I have yet to check whether that other commit can be just dropped, however on your branch 4.4 branch, lm_alias isn't used anywhere, so we probably don't want to backport this particular patch (unless we need to actually backport the other patch in some way).
Cheers,
