Subject: [RESEND PATCH 3/4] um: define set_pte_at() as a static inline function, not a macro

From: Bartosz Golaszewski <bgolaszewski@...libre.com>

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.
