Locking was incorrect for the state machine processing since there are
conditions where both the work queue and the IRQ can be active. This
patch fixes the handling to ensure the spin lock is held whenever the
state machine is being processed.

The name seems a bit unfortunate though, because one could read the

It is kind of a confusing name.

This patch adds CPU selection to Kconfig.cputype. I did my best to make

be
added, but it should be enough for now.

Hi,
this is my second attempt to introduce some tuning options for PPC64. These
patches are much less invasive as the previous patchset.
Because the power cpus seem to have various features I don't know/understand I
didn't touch any feature flags/config options this time, but focused only on
This patch modifies the Makefile to use the new tuning options. Most of the
work
is done in Kconfig now, so this looks a little bit more clearly (except the
broken altivec hack).

I think this code that counts SMT threads and compares against NR_CPUS
is an artifact of pre-powerpc-merge ppc64. We care about starting
only primary threads in the OF client code.

This series consists of a couple of cleanups and a few feature
additions, all of which are more or less related to system topology
(threads, cores, caches, sysfs...) These are independent of
each other except for 4 and 5 (core sibling and core id info).

Rather doing one initialization pass over all the per-cpu
cpu_sibling_maps at boot, update the maps at cpu online/offline time.
This is a behavior change -- the thread_siblings attribute now
reflects only online siblings, whereas it would display offline
siblings before. The new behavior matches
Collect cache information from the OF device tree and display it in
the cpu hierarchy in sysfs. This is intended to be compatible at the
userspace level with x86's implementation[1], hence some of the funny
attribute names. The arrangement of cache info is not immediately
intuitive, but (again)
Existing Open Firmware practice is to report each processor core as a
separate node in the device tree. Report the value of the reg OF
property corresponding to a logical CPU's device node as the core_id
attribute in /sys/devices/system/cpu/cpu*/topology/core_id.
