mainlining shenanigans

Currently, the ghes_poll_func() timer callback is registered with the TIMER_DEFERRABLE flag. Thus, it is run when the CPU eventually wakes up together with a subsequent non-deferrable timer and not at the precisely configured polling interval. For polling mode, the polling interval configured by firmware should not be exceeded according to the ACPI spec 6.3, Table 18-394. The definition of the polling interval is: "Indicates the poll interval in milliseconds OSPM should use to periodically check the error source for the presence of an error condition." If this interval is extended due to the timer callback deferring, error records can get lost. Which we are observing on our ThunderX2 platforms. Therefore, remove the TIMER_DEFERRABLE flag so that the timer callback executes at the precise interval.

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.
