Pull powerpc fixes from Michael Ellerman: - Add perf support for emitting extended registers for power10. - A fix for CPU hotplug on pseries, where on large/loaded systems we may not wait long enough for the CPU to be offlined, leading to crashes. - Addition of a raw cputable entry for Power10, which is not required to boot, but is required to make our PMU setup work correctly in guests. - Three fixes for the recent changes on 32-bit Book3S to move modules into their own segment for strict RWX. - A fix for a recent change in our powernv PCI code that could lead to crashes. - A change to our perf interrupt accounting to avoid soft lockups when using some events, found by syzkaller. - A change in the way we handle power loss events from the hypervisor on pseries. We no longer immediately shut down if we're told we're running on a UPS. - A few other minor fixes.

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.
