Commit 65525488fa86 ("proc: add kpageidle file") introduces code
which depends on MMU_NOTIFIER, yet the newly introduced configuration
flag does not declare that dependency. This results in the following
build failures seen if IDLE_PAGE_TRACKING is configured but MMU_NOTIFIER
is not.
fs/proc/page.c: In function 'kpageidle_clear_pte_refs_one':
fs/proc/page.c:341:4: error:
implicit declaration of function 'pmdp_clear_young_notify'
fs/proc/page.c:347:4: error:
implicit declaration of function 'ptep_clear_young_notify'
Fixes: 65525488fa86 ("proc: add kpageidle file")
