Implement support for restartable sequences on OpenRISC by doing: - Select HAVE_RSEQ in Kconfig - Call rseq_syscall() on return to userspace when CONFIG_DEBUG_RSEQ is enabled. - Call rseq_signal_deliver() to fixup the pre-signal stack frame when a signal is delivered on top of a restartable sequence critical section Cc: Michael Jeanson <mjeanson@efficios.com> Signed-off-by: Stafford Horne <shorne@gmail.com>
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.
