The commit message doesn't really help, since you don't see that one when you
read the header file later. So yes, please.

[PATCH 03/10] KVM: PPC: reserve a capability and ioctl numbers for realmode VFIO
This is to reserve a capablity number for upcoming support
of VFIO-IOMMU DMA operations in real mode.
