e301a08be4 CRIS: Drop code related to obsolete or unused kconfigs
Drop all code related to Kconfigs that don't exist.
Fix one Kconfig where it was actually typo:ed (ETRAX_KGB_PORT2)
Drop content related to CRIS v32 SoCs from etraxgpio.h headerfile,
all use of GPIO for both ETRAX FS and ARTPEC-3 should now be through
standard gpiolib instead.

ab28e96fd1 CRIS v32: remove old GPIO and LEDs code
Since we now have a gpiolib driver, remove this code:

The gpio-etraxfs driver (along with things like gpio-keys-polled for
polling support) replaces the GIO driver implementations in mach-a3 and
mach-fs.  The various generic external chip drivers replace the "virtual
gpio" parts.

The generic gpio-leds driver replaces the LED handling.

a3199ad90a CRISv32: ETRAXFS: Fix recursive spinlock
Move pinmux alloc/dealloc code into functions that don't take
the spinlock so we can use from code that has the spinlock already.

CRISv32 has no working SMP, so spinlocks becomes a NOP,
so deadlock was never seen.

64d8ad933d cris: remove deprecated IRQF_DISABLED
This patch proposes to remove the IRQF_DISABLED flag from CRIS
architecture code. It's a NOOP since 2.6.35 and it will be removed
one day.

Comments mentioning IRQF_DISABLED are also updated, knowing
that all interrupts are now "fast interrupts", their handlers
running with interrupts disabled.

Don't hesitate to let me know if you have other ways of
rephrasing the comments!

This is an update for 3.11 of a patch already sent for 3.10

b43a7ffbf3 cpufreq: Notify all policy->cpus in cpufreq_notify_transition()
policy->cpus contains all online cpus that have single shared clock line. And
their frequencies are always updated together.

Many SMP system's cpufreq drivers take care of this in individual drivers but
the best place for this code is in cpufreq core.

This patch modifies cpufreq_notify_transition() to notify frequency change for
all cpus in policy->cpus and hence updates all users of this API.

459fc208ab cpufreq: remove policy->governor setting in drivers initialization
As policy->governor is already set to CPUFREQ_DEFAULT_GOVERNOR in the
(always built-in) cpufreq core, we do not need to set it in the drivers.
This fixes the sparc64 allmodconfig build failure.

Also, remove a totally useles setting of ->policy in cpufreq-pxa3xx.c.
