-From c022630633624a75b3b58f43dd3c6cc896a56cff Mon Sep 17 00:00:00 2001
-From: Steven J. Hill <sjhill@mips.com>
-Date: Fri, 06 Jul 2012 19:56:01 +0000
-Subject: MIPS: Refactor 'clear_page' and 'copy_page' functions.
-
-Remove usage of the '__attribute__((alias("...")))' hack that aliased
-to integer arrays containing micro-assembled instructions. This hack
-breaks when building a microMIPS kernel. It also makes the code much
-easier to understand.
-
-[ralf@linux-mips.org: Added back export of the clear_page and copy_page
-symbols so certain modules will work again.  Also fixed build with
-CONFIG_SIBYTE_DMA_PAGEOPS enabled.]
