[PATCH v3 4/10] x86/asm: Add pud_pgprot() and pmd_pgprot()

[Toshi Kani]

pte_pgprot() returns a pgprot_t value by calling pte_flags().  Now
that pud_flags() and pmd_flags() work differently from pte_flags(),
define pud_pgprot() and pmd_pgprot() for PUD/PMD.  Also update
pte_pgprot() to remove the masking with PTE_FLAGS_MASK, which is
unnecessary since pte_flags() takes care of it.
