I'll pick this one up too. Will

In some randconfig builds, the new CONFIG_ARM64_USER_VA_BITS_52 triggered a build failure: arch/arm64/mm/proc.S:287: Error: immediate out of range As it turns out, we were incorrectly setting PGTABLE_LEVELS here, lacking any other default value. This fixes the calculation of CONFIG_PGTABLE_LEVELS to consider all combinations again.
