Sibi Sankar d3ae96c0e6 remoteproc: qcom: q6v5: Fix a race condition on fatal crash
Currently with GLINK_SSR enabled each fatal crash results in servicing
a crash from wdog as well. This is due to a race that occurs in setting
the running flag in the shutdown path. Fix this by moving the running
flag to the end of fatal interrupt handler.

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.
