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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
