KVM: PPC: Book3S HV: Fix KVM_RUN clobbering FP/VEC user registers (2023-11-29 22:24:21 +1100)
- ------------------------------------------------------------------
powerpc fixes for 6.7 #3
- Fix corruption of f0/vs0 during FP/Vector save, seen as userspace crashes
when using io-uring workers (in particular with MariaDB).
- Fix KVM_RUN potentially clobbering all host userspace FP/Vector registers.
Thanks to: Timothy Pearson, Jens Axboe, Nicholas Piggin.
