arch/arm64/mm/fault: Fix undeclared variable error in do_page_fault()
Commit ae870a68b5d1 ("arm64/mm: Convert to using lock_mm_and_find_vma()") made do_page_fault() to use 'vma' even if CONFIG_PER_VMA_LOCK is not defined, but the declaration is still in the ifdef. As a result, building kernel without the config fails with undeclared variable error as below: arch/arm64/mm/fault.c: In function 'do_page_fault': arch/arm64/mm/fault.c:624:2: error: 'vma' undeclared (first use in this function); did you mean 'vmap'? 624 | vma = lock_mm_and_find_vma(mm, addr, regs); | ^~~ | vmap Fix it by moving the declaration out of the ifdef. Fixes: ae870a68b5d1 ("arm64/mm: Convert to using lock_mm_and_find_vma()") Signed-off-by: SeongJae Park <sj@kernel.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
