[PATCH v10 34/38] x86/mm: Create native_make_p4d() for PGTABLE_LEVELS <= 4
From: Tom Lendacky
Date: Mon Jul 17 2017 - 17:14:58 EST
Currently, native_make_p4d() is only defined when CONFIG_PGTABLE_LEVELS
is greater than 4. Create a macro that will allow for defining and using
native_make_p4d() when CONFIG_PGTABLES_LEVELS is not greater than 4.
