Allowing spinlock_init() to specify not only a name but also a
'category-specific index' might be okay. For example, domid, in the case of
a domain-specific lock. Hiding the allocation of profiling info structs in
the spinlock subsystem somehow... (e.g., radix tree to make a simple
growable array).
