Linus,

  Linux 6.13-rc6 (2025-01-05 14:13:40 -0800)

  Merge tag 'kvm-s390-master-6.13-1' of https://git.kernel.org/pub/scm/linux/kernel/git/kvms390/linux into HEAD (2025-01-12 12:51:05 +0100)

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.
