KVM x86 fixes for 7.1-rcN - 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. - Fudge around an RCU splat in the emegerncy reboot code that is technically a legitimate flaw, but in practice is a non-issue and fixing the flaw, e.g. by adding locking, would incur meaningful risk, i.e. do more harm than good. - 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.
