  KVM: TDX: Exit to userspace for GetTdVmCallInfo (2025-06-20 13:55:47 -0400)

----------------------------------------------------------------
ARM:

- Fix another set of FP/SIMD/SVE bugs affecting NV, and plugging some
  missing synchronisation

- A small fix for the irqbypass hook fixes, tightening the check and
  ensuring that we only deal with MSI for both the old and the new
  route entry

- Rework the way the shadow LRs are addressed in a nesting
  configuration, plugging an embarrassing bug as well as simplifying
  the whole process

- Add yet another fix for the dreaded arch_timer_edge_cases selftest

RISC-V:

- Fix the size parameter check in SBI SFENCE calls

- Don't treat SBI HFENCE calls as NOPs

x86 TDX:

- Complete API for handling complex TDVMCALLs in userspace.  This was
  delayed because the spec lacked a way for userspace to deny supporting
  these calls; the new exit code is now approved.
