Paolo, sorry for being so late. One feature (enable hardware interpretion of specification exceptions) and one fix targeted for stable. Given the short runway to 5.14 I decided to let this go via next and not try to sneak it into 5.14. The following changes since commit 1f703d2cf20464338c3d5279dddfb65ac79b8782: KVM: s390: allow facility 192 (vector-packed-decimal-enhancement facility 2) (2021-06-23 09:35:20 +0200) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/kvms390/linux.git tags/kvm-s390-next-5.15-1 for you to fetch changes up to a3e03bc1368c1bc16e19b001fc96dc7430573cc8: KVM: s390: index kvm->arch.idle_mask by vcpu_idx (2021-08-27 18:35:41 +0200) ---------------------------------------------------------------- KVM: s390: Fix and feature for 5.15 - enable interpretion of specification exceptions - fix a vcpu_idx vs vcpu_id mixup ---------------------------------------------------------------- Halil Pasic (1): KVM: s390: index kvm->arch.idle_mask by vcpu_idx Janis Schoetterl-Glausch (1): KVM: s390: Enable specification exception interpretation arch/s390/include/asm/kvm_host.h | 2 ++ arch/s390/kvm/interrupt.c | 12 ++++++------ arch/s390/kvm/kvm-s390.c | 4 +++- arch/s390/kvm/kvm-s390.h | 2 +- arch/s390/kvm/vsie.c | 2 ++ 5 files changed, 14 insertions(+), 8 deletions(-)
