When a new remoteproc boots up, send the sysmon state notification of only running remoteprocs. Sending state of remoteprocs booting up in parallel can cause a race between SSR clients of the remoteproc that is booting up and the sysmon notification for the same remoteproc, resulting in an inconsistency between which state the remoteproc that is booting up in parallel. For example - if remoteproc A and B crash one after the other, after remoteproc A boots up, if the remoteproc A tries to get the state of remoteproc B before the sysmon subdevice for B is invoked but after the ssr subdevice of B has been invoked, clients on remoteproc A might get confused when the sysmon notification indicates a different state.

README
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.
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.
