Subject: x86/asm: Add pud_pgprot() and pmd_pgprot()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=bbac8c6deadab921f4b7d00ce675ffa4f358ec7f;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

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.
