[PATCH 0/5] i386: simplify Hyper-V enlightenments enablement

[Vitaly Kuznetsov]

This series is a part of the previously sent "[PATCH RFC v3 00/23] i386:
KVM: expand Hyper-V features early":
https://lists.gnu.org/archive/html/qemu-devel/2020-10/msg02443.html

We're not ready to merge the full patch set yet because the required
KVM capability is only queued for 5.11. We can, however, extract the
part providing 'hyperv=on' option to x86 machine types which is valuable
on its own. Picking up four other patches from the original RFC to
minimize the code churn in future (x86_cpu_realizefn()).

Changes since RFCv3:
- Rename 'hyperv_features' to 'default_hyperv_features' in X86MachineClass
  [Eduardo]
- Move x86_cpu_hyperv_realize() invocation after x86_cpu_expand_features()/
  x86_cpu_filter_features() as we need to reference cpu_has_vmx().

Vitaly Kuznetsov (5):
  i386: move hyperv_vendor_id initialization to x86_cpu_realizefn()
  i386: move hyperv_interface_id initialization to x86_cpu_realizefn()
  i386: move hyperv_version_id initialization to x86_cpu_realizefn()
  i386: move hyperv_limits initialization to x86_cpu_realizefn()
  i386: provide simple 'hyperv=on' option to x86 machine types
