Subject: [PATCH v1 0/2] mm: move pte table reclaim code to memory.c

Some cleanups for PT table reclaim code, triggered by a false-positive
warning we might start to see soon after we unlocked pt-reclaim on
architectures besides x86-64.

Cross compiled on plenty of architectures, tested on x86-64 with
a simple test case that allocates plenty of page tables in a sparse
memory area to see if they will get reclaimed.
