Pull kvm fixes from Paolo Bonzini:
 "x86 and selftests fixes.

  x86:

   - When emulating a guest TLB flush for a nested guest, flush vpid01,
     not vpid02, if L2 is active but VPID is disabled in vmcs12, i.e. if
     L2 and L1 are sharing VPID '0' (from L1's perspective).

   - Fix a bug in the SNP initialization flow where KVM would return '0'
     to userspace instead of -errno on failure.

   - Move the Intel PT virtualization (i.e. outputting host trace to
     host buffer and guest trace to guest buffer) behind CONFIG_BROKEN.

   - Fix memory leak on failure of KVM_SEV_SNP_LAUNCH_START

   - Fix a bug where KVM fails to inject an interrupt from the IRR after
     KVM_SET_LAPIC.

  Selftests:

   - Increase the timeout for the memslot performance selftest to avoid
     false failures on arm64 and nested x86 platforms.

   - Fix a goof in the guest_memfd selftest where a for-loop initialized
     a bit mask to zero instead of BIT(0).

   - Disable strict aliasing when building KVM selftests to prevent the
     compiler from treating things like "u64 *" to "uint64_t *" cases as
     undefined behavior, which can lead to nasty, hard to debug
     failures.

   - Force -march=x86-64-v2 for KVM x86 selftests if and only if the
     uarch is supported by the compiler.

   - Fix broken compilation of kvm selftests after a header sync in
     tools/"
