Fixes for a rather interesting set of bugs relating to the MMU:
- Read the MMU notifier seq before dropping the mmap lock to guard
against reading a potentially stale VMA
- Disable interrupts when walking user page tables to protect against
the page table being freed
- Read the MTE permissions for the VMA within the mmap lock critical
section, avoiding the use of a potentally stale VMA pointer
Additionally, some fixes targeting the vPMU:
- Return the sum of the current perf event value and PMC snapshot for
reads from userspace
- Don't save the value of guest writes to PMCR_EL0.{C,P}, which could
otherwise lead to userspace erroneously resetting the vPMU during VM
save/restore

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.
