From c022630633624a75b3b58f43dd3c6cc896a56cff Mon Sep 17 00:00:00 2001 From: "Steven J. Hill" Date: Fri, 6 Jul 2012 21:56:01 +0200 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.] Signed-off-by: Steven J.
