I was also thinking toward NUMA systems where I'd like to know which

before secondary processors are selected.

I'd rather see domain creation take both max_vcpus and cpu placement
bitmaps instead, but if that is not acceptable for 3.0, I'll go ahead

I'd rather keep single-purpose dom0 ops than have createdomain become a 'union of everything'.

There is already a dom0 op for pinning a vcpu. Right now it can't be used before the domain starts for other than vcpu0 since it requires VCPUOP_create to allocate the vcpu structure, but fixing that is unrelated to whether pin info is passed to DOM0_CREATEDOMAIN. As you say, it's also not critical to fix for 3.0.
