Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm

Pull kvm fixes from Paolo Bonzini:
 "The largest part here is for KVM/PPC, where a NULL pointer dereference
  was introduced in the 6.13 merge window and is now fixed.

  There's some "holiday-induced lateness", as the s390 submaintainer put
  it, but otherwise things looks fine.

  s390:

   - fix a latent bug when the kernel is compiled in debug mode

   - two small UCONTROL fixes and their selftests

  arm64:

   - always check page state in hyp_ack_unshare()

   - align set_id_regs selftest with the fact that ASIDBITS field is RO

   - various vPMU fixes for bugs that only affect nested virt

  PPC e500:

   - Fix a mostly impossible (but just wrong) case where IRQs were never
     re-enabled

   - Observe host permissions instead of mapping readonly host pages as
     guest-writable. This fixes a NULL-pointer dereference in 6.13

   - Replace brittle VMA-based attempts at building huge shadow TLB
     entries with PTE lookups"

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.
