[PATCH] um: define set_pte_at() as a static inline function, not a macro

From: Bartosz Golaszewski
Date: Wed Mar 13 2019 - 06:14:47 EST


From: Bartosz Golaszewski <bgolaszewski@xxxxxxxxxxxx>

When defined as macro, the mm argument is unused and subsequently the
variable passed as mm is considered unused by the compiler. This fixes
a build warning.
