Systems based on Intel platforms that use the MSFT UUID for Low-Power S0 Idle (LPS0) have started to ship, so allow the kernel to use the MSFT UUID in the non-AMD case too, but in that case make it avoid evaluating the same _DSM function for two different UUIDs and prioritize the MSFT one. While at it, combine two MSFT _DSM function mask checks in acpi_s2idle_restore_early() so as to make it reflect the acpi_s2idle_prepare_late() flow more closely and adjust the Modern Standby entry and exit comments slightly. Non-AMD systems that do not support MSFT UUID for Low-power S0 Idle are not expected to be affected by this change in any way. Signed-off-by: Rafael J.

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.
