Rafael J. Wysocki 99ae2bd077 Revert "ACPICA: Clear status of GPEs before enabling them" 
commit 2c2a2fb1e2 upstream.

Revert commit c8b1917c89 ("ACPICA: Clear status of GPEs before
enabling them") that causes problems with Thunderbolt controllers
to occur if a dock device is connected at init time (the xhci_hcd
and thunderbolt modules crash which prevents peripherals connected
through them from working).

Commit c8b1917c89 effectively causes commit ecc1165b8b ("ACPICA:
Dispatch active GPEs at init time") to get undone, so the problem
addressed by commit ecc1165b8b appears again as a result of it.

Fixes: c8b1917c89 ("ACPICA: Clear status of GPEs before enabling them")

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
