X-Git-Tag: v4.14-rc1~4765^2~22
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=766ffb69803943c2b580a44ac14a189b875d21f6;p=platform%2Fkernel%2Flinux-rpi.git

arm64: pgtable: fix definition of pte_valid

pte_valid should check if the PTE_VALID bit (1 << 0) is set in the pte,
so fix the macro definition to use bitwise & instead of logical &&.
