[PATCH v4 5/11] x86/asm: Add pud_pgprot() and pmd_pgprot()

From: Toshi Kani
Date: Tue Aug 25 2015 - 17:57:37 EST

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.
