Linus Torvalds 0a1da2dde4 sparc32: fix lock_mm_and_find_vma() conversion ... commit 0b26eadbf2 upstream. The sparc32 conversion to lock_mm_and_find_vma() in commit a050ba1e74 ("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.
