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,
