This is a comtinuation of "KVM: x86: Drop arbitraty KVM_SOFT_MAX_VCPUS" (https://lore.kernel.org/kvm/20211111134733.86601-1-vkuznets@redhat.com/ (local)) work. 1) Enforce KVM_CAP_NR_VCPUS <= KVM_CAP_MAX_VCPUS rule on all architectures. [Sean Christopherson] 2) Make KVM_CAP_NR_VCPUS return num_online_cpus() and not an arbitrary value of '710' on x86. Everything but x86 was only 'eyeball tested', the change is trivial but sorry in advance if I screwed up)Christian, can you look at this for s390? Returning a fixed value seems wrong for KVM_CAP_NR_VCPUS.
will do. (Sorry I was OOO the last days).
Thanks, Paoloquoted
