[PATCH v4 00/28] KVM: combined patchset for MBEC/GMET support

[Paolo Bonzini <pbonzini@redhat.com>]

I will send you to v3 (https://lore.kernel.org/kvm/20260408154217.458420-1-pbonzini@redhat.com/)
for the description of the series, and leave a short list of changes:

- patch 15: clear enable_mbec = 0 if enable_ept == 0
- patches 23-27: adjust for rename of nested_ctl to misc_ctl
- patch 24: new
- patch 27: disable svm_get_cpl for SEV-ES/SEV-SNP
- patch 28: fix commit message reference to __nested_svm_check_controls 

(patch 24 is the only major bugfix).

Thanks,

Paolo
