Since commit 0cbe3e26abe0cfe7 ("mm: update ptep_modify_prot_start/commit
to take vm_area_struct as arg"), using gcc 8.2.0:
mm/mprotect.c: In function ‘change_pte_range’:
mm/mprotect.c:42:20: warning: unused variable ‘mm’ [-Wunused-variable]
struct mm_struct *mm = vma->vm_mm;
^~
Fix this by converting set_pte_at() from a macro to a static inline
function.
