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/
