Subject: mm, x86: fix HIGHMEM64 && PARAVIRT build config for native_pud_clear()
Looks like I also missed the build config that includes CONFIG_HIGHMEM64G
&& CONFIG_PARAVIRT to export the native_pud_clear() dummy function.
Fixes: a00cc7d9dd93d ("mm, x86: add support for PUD-sized transparent hugepages")
