From bbac8c6deadab921f4b7d00ce675ffa4f358ec7f Mon Sep 17 00:00:00 2001 From: Toshi Kani Date: Thu, 17 Sep 2015 12:24:18 -0600 Subject: [PATCH] x86/asm: Add pud_pgprot() and pmd_pgprot() pte_pgprot() returns a pgprot_t value by calling pte_flags(). Now that pud_flags() and pmd_flags() work specifically for the pud/pmd levels, define pud_pgprot() and pmd_pgprot() for PUD/PMD. Also update pte_pgprot() to remove the unnecessary mask with PTE_FLAGS_MASK as pte_flags() takes care of it. Signed-off-by: Toshi Kani Cc: Andrew Morton Cc: Juergen Gross Cc: H.
