Ping.
What did you think of my suggestion in the other thread of hashing
the info we need to determine the cpreg set (ID regs, feature flags,
etc) and using that to look up whether we've already created a
cpreg hashtable for this config? If we did that, we could refcount
the cpreg hashtable and only free it when all CPUs are done with
it, which would mean we don't need this indirection.
I thought it a decent idea, but not small.
While we currently have a struct for some isar regs, we'd want a larger struct containing
every bit of info that wants hashing. I think it would take 40-50 patches to get all of
the properties etc moved out of ARMCPU and CPUARMState.
Anyway, I didn't want to leave the user-only thread leak blocked in the
meantime.
