#     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.
#
