I can certainly apply this. But it seems to me that this kind of code

All powerpc platforms share the same cpu_bootable hook, which does nothing
but { return 1 }. It is not needed anymore. Let's drop it at last.

The following assertions are always true:
- threads_per_core > 0
- cpu & (threads_per_core - 1) < threads_per_core
It means smp_generic_cpu_bootable() always returns true.

The smt-enabled kernel parameter basically leaves unwanted cpus executing
in firmware or wherever they happen to be. The very same applies to the
ibm,smt-enabled DT property which is no more used by anything known. These
are hacks that shoudn't be used in a production environment.

As requested by mpe, this series now covers both the smt-enabled
kernel parameter and the ibm,smt-enabled property. The cleanup was
split into 3 separate patches to ease review, but I guess they
could be folded into a single patch as well.

Hi Preeti,
Moving this out of the architecture code looks good to me!
I have a couple of minor comments below.

Commit 5d1638acb9f62fa7 added a hrtimer based broadcast mode for those
platforms in which local timers stop when CPUs enter deep idle states. The
commit expected the platforms to register for this mode explicitly when they
lacked a better external device to wake up CPUs in deep idle. Given that

Currently when we back trace something that is in a syscall we see
something like this:
[c000] [c000] SyS_read+0x6c/0x110

Although it's entirely correct, seeing syscall_exit at the bottom can be
