From cadbfd01468663e8b9f9518a58ef67398a20d06b Mon Sep 17 00:00:00 2001 From: LEROY Christophe Date: Mon, 19 Jan 2015 17:04:44 +0100 Subject: powerpc/8xx: use _PAGE_RO instead of _PAGE_RW On powerpc 8xx, in TLB entries, 0x400 bit is set to 1 for read-only pages and is set to 0 for RW pages. So we should use _PAGE_RO instead of _PAGE_RW Signed-off-by: Christophe Leroy Signed-off-by: Scott Wood --- arch/powerpc/kernel/head_8xx.S | 3 --- 1 file changed, 3 deletions(-) (limited to 'arch/powerpc/kernel/head_8xx.S') diff --git a/arch/powerpc/kernel/head_8xx.S b/arch/powerpc/kernel/head_8xx.S index d99aac0d69f1..65492d043964 100644 --- a/arch/powerpc/kernel/head_8xx.S +++ b/arch/powerpc/kernel/head_8xx.S @@ -441,9 +441,6 @@ DataStoreTLBMiss: and r11, r11, r10 rlwimi r10, r11, 0, _PAGE_PRESENT #endif - /* invert RW */ - xori r10, r10, _PAGE_RW - /* The Linux PTE won't go exactly into the MMU TLB. * Software indicator bits 22 and 28 must be clear. * Software indicator bits 24, 25, 26, and 27 must be -- cgit v1.2.3
