Of course pgtable.h is included in this file -- we have direct references to
L_PTE_MT_UNCACHED, for example, so by your logic we should inline all of
that too!
Yes, there are other CONFIG_ARM_LPAE checks in this file, but only where
there's a piece of code that is not applicable one way or the other. For
data definitions, it's really easy to fix in the headers so please do it
there instead.
