Merge tag 'kvm-x86-tdx-6.19' of https://github.com/kvm-x86/linux into HEAD
KVM TDX changes for 6.19:
- Overhaul the TDX code to address systemic races where KVM (acting on behalf
of userspace) could inadvertantly trigger lock contention in the TDX-Module,
which KVM was either working around in weird, ugly ways, or was simply
oblivious to (as proven by Yan tripping several KVM_BUG_ON()s with clever
selftests).
- Fix a bug where KVM could corrupt a vCPU's cpu_list when freeing a vCPU if
creating said vCPU failed partway through.
- Fix a few sparse warnings (bad annotation, 0 != NULL).
- Use struct_size() to simplify copying capabilities to userspace.
