From: Dave Hansen <dave@...ux.vnet.ibm.com>
To: linux-arch@...r.kernel.org
Cc: linux-kernel@...r.kernel.org, Dave Hansen <dave@...ux.vnet.ibm.com>
Subject: [RFC v2][PATCH 32/35] Move users to asm-generic/ptemap.h
Now that we have everyone using pte_offset_kernel(),
we can plainy see that almost all the implementations
are exactly the same.
This takes all of those and moves them over to use
esm-generic/ptemap.h instead.
