Hello

Patch 1/2 mainly to fix the bug when calling kexec_load() originally, but
because of ignored and link[1] also fixed this bug and had been applied
to arm64 (for-next/fixes) before us. Anyway, It's nice to unify the use of
'pmd_populate_kernel' under arm64.

Patch 2/2 just make a very simple optimization, reducing
calls to page_address() in kexec_page_alloc().

v2 -> v3:
- Patch "arm64: trans_pgd: unify the use of pmd_populate_kernel"
rename this patch.

v1 -> v2:
- Patch " arm64: trans_pgd: fix incorrect use of pmd_populate_kernel in
  copy_pte()"
restore the usage of pmd_populate_kernel.
