Subject: [PATCH] mm: remove set_pgdir leftovers
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2492ecc1a16b8ccf679d2999dca4f1b48aef07ee;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[PATCH] mm: remove set_pgdir leftovers

set_pgdir isn't needed anymore for a very long time.  Remove the leftover
implementation on sh64 and the stub on s390.
