#     sparc32: fix lock_mm_and_find_vma() conversion
#     
#     The sparc32 conversion to lock_mm_and_find_vma() in commit a050ba1e7422
#     ("mm/fault: convert remaining simple cases to lock_mm_and_find_vma()")
#     missed the fact that we didn't actually have a 'regs' pointer available
#     in the 'force_user_fault()' case.
#     
#     It's there in the regular page fault path ("do_sparc_fault()"), but not
#     the window underflow/overflow paths.
#     
#     Which is all fine - we can just pass in a NULL pointer.  The register
#     state is only used to avoid deadlock with kernel faults, which is not
#     the case for any of these register window faults.
