Paolo Bonzini 0afd104fb3 KVM/arm64 updates for 6.15
- Nested virtualization support for VGICv3, giving the nested
    hypervisor control of the VGIC hardware when running an L2 VM
 
  - Removal of 'late' nested virtualization feature register masking,
    making the supported feature set directly visible to userspace
 
  - Support for emulating FEAT_PMUv3 on Apple silicon, taking advantage
    of an IMPLEMENTATION DEFINED trap that covers all PMUv3 registers
 
  - Paravirtual interface for discovering the set of CPU implementations
    where a VM may run, addressing a longstanding issue of guest CPU
    errata awareness in big-little systems and cross-implementation VM
    migration
 
  - Userspace control of the registers responsible for identifying a
    particular CPU implementation (MIDR_EL1, REVIDR_EL1, AIDR_EL1),
    allowing VMs to be migrated cross-implementation
 
  - pKVM updates, including support for tracking stage-2 page table
    allocations in the protected hypervisor in the 'SecPageTable' stat
 
  - Fixes to vPMU, ensuring that userspace updates to the vPMU after
    KVM_RUN are reflected into the backing perf events

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.
