Subject: [PATCH v4 5/11] x86/asm: Add pud_pgprot() and pmd_pgprot()
Date: Tue, 25 Aug 2015 15:55:05 -0600 [thread overview]
Message-ID: <1440539711-2985-6-git-send-email-toshi.kani@hp.com> (raw)
In-Reply-To: <1440539711-2985-1-git-send-email-toshi.kani@hp.com>
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.
