Because, I intended to have the only five catogory under "Supported hypercall
interfaces":
- sysctl
- domctl
- hvm
- physdev
- platform
Which will be introduced in a patch serie and may contain multiple different
features.
PM_OP is more or less a feature to me. And it is only dependent on SYSCTL, like
LIVEPATCH, etc
