CPER records describing a firmware-first error are identified by GUID. The ghes driver currently logs, but ignores any unknown CPER records. This prevents describing errors that can't be represented by a standard entry, that would otherwise allow a driver to recover from an error. The UEFI spec calls these 'Non-standard Section Body' (N.2.3 of version 2.8). Add a notifier chain for these non-standard/vendor-records. Callers must identify their type of records by GUID. Record data is copied to memory from the ghes_estatus_pool to allow us to keep it until after the notifier has run.

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.
