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.
