Subject: [PATCH V2 0/2] Lift memcpy_[to|from]_page to core

From: Ira Weiny <ira.weiny@...el.com>

These are based on tip/core/mm.  As I was looking at converting the calls to
kmap_local_page() I realized that there were a number of calls in highmem.h
which should also be converted.

So I've added a second prelim patch to convert those.

This is a V2 to get into 5.11 so that we can start to convert all the various
subsystems in 5.12.[1]

I'm sending to Andrew and Thomas but I'm expecting these to go through
tip/core/mm via Thomas if that is ok with Andrew.
