    Pull kvm fixes from Paolo Bonzini:
     "arm64:

       - Restore CONFIG_PKVM_DISABLE_STAGE2_ON_PANIC to its former glory by
         making sure the config symbol is correctly spelled out in the code

       - Don't reset the AArch32 view of the PMU counters to zero when the
         guest is writing to them

       - Fix an assorted collection of memory leaks in the newly added
         tracing code

       - Fix the capping of ZCR_EL2 which could be used in an unsanitised
         way by an L2 guest

      x86:

       - Include the kernel's linux/mman.h in KVM selftests to ensure
         MADV_COLLAPSE is defined, as older libc versions may not provide
         it.

       - Include execinfo.h if and only if KVM selftests are building
         against glibc, and provide a test_dump_stack() for non-glibc
         builds.

       - Silence an annoying RCU splat on (even non-KVM-related) panics.

         The splat is technically legit, but in practice not an issue. To
         have a race, you would need to unload the KVM modules at exactly
         the time a panic happens; and speaking of incredibly rare races,
         taking the locks risks introducing a deadlock if the module unload
         code took the lock on a CPU that has been halted. Which seems
         possibly more likely than the RCU grace period issue, so just shut
         it up. This code used to be in KVM but is now outside it; but the
         x86 maintainers haven't picked it up, so here we are.

       - Rate-limit global clock updates once again (but without delayed
         work), as KVM was subtly relying on the old rate-limiting for NPT
         correction to guard against "update storms" when running without a
         master clock on systems with overcommitted CPUs.

       - Fix a brown paper bag goof where KVM checked if ERAPS is "dirty"
         instead of marking it dirty when emulating INVPCID.

       - Flush the TLB when transitioning from xAVIC => x2AVIC to ensure the
         CPU TLB doesn't contain AVIC-tagged entries for the APIC base GPA.

       - The top 10 commits fix buffer overflow (and potential TOC/TOU)
         flaws in the page state change protocol for encrypted VMs. AI
         models find it quite easily given it was reported three times, but
         aren't as good at writing a comprehensive fix. There's more to
         clean up in the area, which will come in 7.2"
