Subject: [PATCH] x86_64: Get rid of pud_offset_k / __pud_offset_k
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d2ae5b5f6afd3c4caaf82444102a4372135cb994;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[PATCH] x86_64: Get rid of pud_offset_k / __pud_offset_k

pud_offset_k() equivalent to pud_offset() now.  Pointed out by Jan Beulich
Similar for __pud_offset_ok, which needs a small change in the callers.
