This patch adds feature negotiation and ssr ack feature between local host and remote processor. Local host can negotiate on common features supported with remote processor. When ssr ack feature bit is set, the remote processor will tell local host when it is reinitialized. All clients registered for falling edge interrupts will be notified when the smp2p entries are cleared for ssr.

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.
