Anshuman Khandual 5093c5872b mm/vma: append unlikely() while testing VMA access permissions ... It is unlikely that an inaccessible VMA without required permission flags will get a page fault. Hence lets just append unlikely() directive to such checks in order to improve performance while also standardizing it across various platforms.
