    Subject[RESEND PATCH 3/4] um: define set_pte_at() as a static inline function, not a macro
    Date
    From: Bartosz Golaszewski <bgolaszewski@baylibre.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.
