Paolo Bonzini 8cbb0df294 KVM/arm64 changes for 6.17, round #3
- Invalidate nested MMUs upon freeing the PGD to avoid WARNs when
    visiting from an MMU notifier
 
  - Fixes to the TLB match process and TLB invalidation range for
    managing the VCNR pseudo-TLB
 
  - Prevent SPE from erroneously profiling guests due to UNKNOWN reset
    values in PMSCR_EL1
 
  - Fix save/restore of host MDCR_EL2 to account for eagerly programming
    at vcpu_load() on VHE systems
 
  - Correct lock ordering when dealing with VGIC LPIs, avoiding scenarios
    where an xarray's spinlock was nested with a *raw* spinlock
 
  - Permit stage-2 read permission aborts which are possible in the case
    of NV depending on the guest hypervisor's stage-2 translation
 
  - Call raw_spin_unlock() instead of the internal spinlock API
 
  - Fix parameter ordering when assigning VBAR_EL1

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 reStructuredText 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.
