From mboxrd@z Thu Jan 1 00:00:00 1970 From: santosh.shilimkar@ti.com (Santosh Shilimkar) Date: Wed, 29 Sep 2010 22:13:16 +0530 Subject: [PATCH] ARM: mmu: Fix MT_MEMORY and MT_MEMORY_NONCACHED pte flags Message-ID: <1285778596-12560-1-git-send-email-santosh.shilimkar@ti.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org The commit f1a2481c0 sets up the default flags for MT_MEMORY and MT_MEMORY_NONCACHED memory types. L_PTE_USER flag is wrongly set as default for these entries so remove it. Also adding the 'L_PTE_WRITE' flag so that these pages become read-write instead of just being read-only Signed-off-by: Santosh Shilimkar Reported-by: Catalin Marinas Cc: Catalin Marinas Cc: Russell King --- arch/arm/mm/mmu.c | 4 ++-- 1 files changed, 2 insertions(+), 2 deletions(-) diff --git a/arch/arm/mm/mmu.c b/arch/arm/mm/mmu.c index 6a3a2d0..e8ed9dc 100644 --- a/arch/arm/mm/mmu.c +++ b/arch/arm/mm/mmu.c @@ -248,7 +248,7 @@ static struct mem_type mem_types[] = { }, [MT_MEMORY] = { .prot_pte = L_PTE_PRESENT | L_PTE_YOUNG | L_PTE_DIRTY | - L_PTE_USER | L_PTE_EXEC, + L_PTE_WRITE | L_PTE_EXEC, .prot_l1 = PMD_TYPE_TABLE, .prot_sect = PMD_TYPE_SECT | PMD_SECT_AP_WRITE, .domain = DOMAIN_KERNEL, @@ -259,7 +259,7 @@ static struct mem_type mem_types[] = { }, [MT_MEMORY_NONCACHED] = { .prot_pte = L_PTE_PRESENT | L_PTE_YOUNG | L_PTE_DIRTY | - L_PTE_USER | L_PTE_EXEC | L_PTE_MT_BUFFERABLE, + L_PTE_WRITE | L_PTE_EXEC | L_PTE_MT_BUFFERABLE, .prot_l1 = PMD_TYPE_TABLE, .prot_sect = PMD_TYPE_SECT | PMD_SECT_AP_WRITE, .domain = DOMAIN_KERNEL, -- 1.6.0.4
