  KVM: SEV: uapi: fix typo in SEV_RET_INVALID_CONFIG (2024-08-14 13:05:42 -0400)

Another largish pull request; this time though it's more the number
of patches than the size, and there's nothing scary in it.

----------------------------------------------------------------
s390:

* Fix failure to start guests with kvm.use_gisa=0

* Panic if (un)share fails to maintain security.

ARM:

* Use kvfree() for the kvmalloc'd nested MMUs array

* Set of fixes to address warnings in W=1 builds

* Make KVM depend on assembler support for ARMv8.4

* Fix for vgic-debug interface for VMs without LPIs

* Actually check ID_AA64MMFR3_EL1.S1PIE in get-reg-list selftest

* Minor code / comment cleanups for configuring PAuth traps

* Take kvm->arch.config_lock to prevent destruction / initialization
  race for a vCPU's CPUIF which may lead to a UAF

x86:

* Disallow read-only memslots for SEV-ES and SEV-SNP (and TDX)

* Fix smatch issues

* Small cleanups

* Make x2APIC ID 100% readonly

* Fix typo in uapi constant

Generic:

* Use synchronize_srcu_expedited() on irqfd shutdown
