From 8bb809df6919f927bcb910bbc852d5724eaa1eb9 Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Tue, 10 Jul 2007 17:32:56 +0100 Subject: [PATCH] [MIPS] Cleanup TO_PHYS_MASK definition No point in adding yet another #ifdef for Loongson since all this mask is being used for is converting an XKPHYS address into a physical address anyway. So replace all definitions by one with the highest architectural possible value.
