Subject: ARM: nommu: provide dummy cpu_switch_mm implementation
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=02ed1c7bba57b66c9a2f3146c935af12a93f2d76;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ARM: nommu: provide dummy cpu_switch_mm implementation

cpu_switch_mm is a logical nop on nommu systems, so define it as such
when !CONFIG_MMU.
