- Fix pKVM error path on init, making sure we do not change critical system registers as we're about to fail - Make sure that the host's vector length is at capped by a value common to all CPUs - Fix kvm_has_feat*() handling of "negative" features, as the current code is pretty broken - Promote Joey to the status of official reviewer, while James steps down -- hopefully only temporarly -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEn9UcU+C1Yxj9lZw9I9DQutE9ekMFAmb++hkACgkQI9DQutE9 ekNDyQ/9GwamcXC4KfYFtfQrcNRl/6RtlF/PFC0R6iiD1OoqNFHv2D/zscxtOj5a nw3gbof1Y59eND/6dubDzk82/A1Ff6bXpygybSQ6LG6Jba7H+01XxvvB0SMTLJ1S 7hREe6m1EBHG/4VJk2Mx8iHJ7OjgZiTivojjZ1tY2Ez3nSUecL8prjqBFft3lAhg rFb20iJiijoZDgEjFZq/gWDxPq5m3N51tushqPRIMJ6wt8TeLYx3uUd2DTO0MzG/ 1K2vGbc1O6010jiR+PO3szi7uJFZfb58IsKCx7/w2e9AbzpYx4BXHKCax00DlGAP 0PiuEMqG82UXR5a58UQrLC2aonh5VNj7J1Lk3qLb0NCimu6PdYWyIGNsKzAF/f4s tRVTRqcPr0RN/IIoX9vFjK3CKF9FcwAtctoO7IbxLKp+OGbPXk7Fk/gmhXKRubPR +4L4DCcARTcBflnWDzdLaz02fr13UfhM80mekJXlS1YHlSArCfbrsvjNrh4iL+G0 UDamq8+8ereN0kT+ZM2jw3iw+DaF2kg24OEEfEQcBHZTS9HqBNVPplqqNSWRkjTl WSB79q1G6iOYzMUQdULP4vFRv1OePgJzg/voqMRZ6fUSuNgkpyXT0fLf5X12weq9 NBnJ09Eh5bWfRIpdMzI1E1Qjfsm7E6hEa79DOnHmiLgSdVk3M9o= =Rtrz -----END PGP SIGNATURE----- Merge tag 'kvmarm-fixes-6.12-1' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD KVM/arm64 fixes for 6.12, take #1 - Fix pKVM error path on init, making sure we do not change critical system registers as we're about to fail - Make sure that the host's vector length is at capped by a value common to all CPUs - Fix kvm_has_feat*() handling of "negative" features, as the current code is pretty broken - Promote Joey to the status of official reviewer, while James steps down -- hopefully only temporarly
