Usually pgtable_l5_enabled is defined using cpu_feature_enabled(). cpu_feature_enabled() is not available in early boot code. We use several different preprocessor tricks to get around it. It's messy. Unify them all. If cpu_feature_enabled() is not yet available, USE_EARLY_PGTABLE_L5 can be defined before all includes. It makes pgtable_l5_enabled rely on __pgtable_l5_enabled variable instead. This approach fits all early users. Signed-off-by: Kirill A.
