Benjamin Berg 4793d76b82 um: use proper care when taking mmap lock during segfault ... [ Upstream commit 6767e8784c ] Segfaults can occur at times where the mmap lock cannot be taken. If that happens the segfault handler may not be able to take the mmap lock. Fix the code to use the same approach as most other architectures. Unfortunately, this requires copying code from mm/memory.c and modifying it slightly as UML does not have exception tables.
