Implement support for restartable sequences on MIPS, which requires 3
simple things:
- Call rseq_handle_notify_resume() on return to userspace if
TIF_NOTIFY_RESUME is set.
- Call rseq_signal_deliver() to fixup the pre-signal stack frame when
a signal is delivered whilst executing a restartable sequence
critical section.
- Select CONFIG_HAVE_RSEQ.

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 Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
