* Address some fallout of the locking rework, this time affecting
the way the vgic is configured
* Fix an issue where the page table walker frees a subtree and
then proceeds with walking what it has just freed...
* Check that a given PA donated to the guest is actually memory
(only affecting pKVM)
* Correctly handle MTE CMOs by Set/Way
* Fix the reported address of a watchpoint forwarded to userspace
* Fix the freeing of the root of stage-2 page tables
* Stop creating spurious PMU events to perform detection of the
default PMU and use the existing PMU list instead.
x86:
* Fix a memslot lookup bug in the NX recovery thread that could
theoretically let userspace bypass the NX hugepage mitigation
* Fix a s/BLOCKING/PENDING bug in SVM's vNMI support
* Account exit stats for fastpath VM-Exits that never leave the super
tight run-loop
* Fix an out-of-bounds bug in the optimized APIC map code, and add a
regression test for the race.

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.
