Save the "affected_cpu_map" used in SMT-aware drivers in struct
cpufreq_policy->(cpumask_t) cpus, and use it wherever possible. In
most cases, the ->get() function is only allowed to run on one CPU [the
one passed as argument] to keep code simpler, and as that code path
isn't executed often, and only root can do it anyway.

The cpufreq core properly gets and puts the modules it calls, including
governors. So there's no need to keep the racy in-module calls in
cpufreq_userspace denoting otherwise.

The encoding of the MSR only works as described in extract_clock() on
certain EST-enabled CPUs. So, limit the actual MSR check to these CPUs.

arm cpufreq Kconfig enhancements:
- don't force the deprecated 24_API on SA11x0 any more, as it will be removed
  ~2005-01-01 and different interfaces have been available for a long time
- don't mark CPU_FREQ as being EXPERIMENTAL any longer
- re-order it in the same way other arches are ordered

x86_64 cpufreq Kconfig fixes:
- SPEEDSTEP_CENTRINO _needs_ the ACPI perflib as the tables are for
  Banias only, and the Banias is only 32bit
- SPEEDSTEP_CENTRINO_TABLE won't be built in any longer as it only wastes space
- /proc/acpi/processor/../performance is available for all ACPI perflib drivers

i386 cpufreq Kconfig fixes:
- /proc/acpi/processor/../performance is available for all ACPI perflib drivers
- powernow-k8 depends on FREQ_TABLE
- clarify the heavy dependency of SPEEDSTEP_CENTRINO on ACPI
- remove the EXPERIMENTAL tag of SPEEDSTEP_CENTRINO_ACPI
- allow to disable SPEEDSTEP_CENTRINO_TABLE

Just test the end case inside the loop, rather than trying to
be clever and getting it wrong.

The previous single-step patch ("make single-step into signal delivery
stop in handler") took things a little too far. 

It left TF set in the sigcontext on the stack, so a PTRACE_CONT after
stopping at the handler entry will step instead of resume.  This
additional patch fixes it.

timer_create leaks task_structs.  I probably introduced this bug when I did
the cleanup making posix-timers properly per-process.  This patch fixes it.

There is also a fixup for a random indentation snafu at the end.

AMD recently errata'd the definition of the PSB/PST for recent Athlon 64 and Opteron parts.  The errata
allows for a second, identical PST for those parts.
The current powernow-k8 driver will not work in PST/PSB mode on those parts because it requires 
there be 1 and only 1 PST.

Please ignore previous patch: set_irq_type takes the IRQ number and
not the GPIO number so using any variant on IRQ_TO_GPIO* is incorrect
anyway.

- Don't chain assignment to volatile registers.
  Doing otherwise generates extra needless code to reload the value
  for the next assignment.
