get_cpu_{idle,iowait}_time_us update idle/iowait counters unconditionally
if the given CPU is in the idle loop.  This doesn't work well outside of
CPU governors which are singletons so nobody (except for IRQ) can race
with them.

We will need to use both functions from /proc/stat handler to properly
handle nohz idle/iowait times.

Let's update those counters only if the given last_update_time parameter
is non-NULL which means that the caller is interested in updating.

update_ts_time_stat currently updates idle time even if we are in iowait
loop at the moment.  The only real users of the idle counter (via
get_cpu_idle_time_us) are CPU governors and they expect to get cumulative
time for both idle and iowait times.  The value (idle_sleeptime) is also
printed to userspace by print_cpu but it prints both idle and iowait times
so the idle part is misleading.

Let's clean this up and fix update_ts_time_stat to account both counters
properly and update consumers of idle to consider iowait time as well.  If
we do this we might use get_cpu_{idle,iowait}_time_us from other contexts
as well and we will get expected values.

This patchset aims at addressing /proc/stat issue which has been
introduced with tickless kernel.  In short, show_stat (proc handler)
relies on kstat_cpu(i).cpustat statistics which are updated periodically
so those numbers are more or less accurate.

This is, however, not true with tickless kernel for idle and iowait
counters because those are not updated while the cpu is in the tickless
state.  As the time when CPU might be tickless is not bounded, we can see
really outdated values.

The biggest problem is that tools which read /proc/stat interpret
unchanged idle/iowait numbers as 0% idle/iowait which might confuse those
who rely on them.

The first patch in this series is just a minor clean-up.

The second one changes update_ts_time_stat semantic.  The current
implementation updates idle counter regardless we are in iowait loop at
the moment.  I see it as an optimization because cpufreq drivers, which
are only users of those counters, care about busy vs.  non-busy states so
idle+iowait makes perfect sense.  This, however, makes idle counter
useless for others.

I think that using get_cpu_idle_time_us + get_cpu_iowait_time_us should
have the same meaning (at least this is what we do for jiffies variants).

The third patch changes get_cpu_{idle,iowait}_time_us semantic.  Both
functions call update_ts_time_stat so they update counters as a side
effect.  This should be OK most of the time as governors (the only users)
are singletons.  I can still see a potential problem because they might
race with IRQ:

irq_enter
  tick_check_idle
    tick_check_nohz
      tick_nohz_stop_idle

but this is a separate issue IMO.

Anyway, we shouldn't update those counters from other contexts so let's
make updating conditional based on the last_update_time parameter.

The final patch is the actual fix.  It uses get_cpu_{idle,iowait}_time_us
to get precise counters.  We still fall back to kstat_cpu if tickless
kernel is disabled.

The patchset is based on top of and gave it some testing (although I am
still not sure about the cpufreq part and possible side effects).  My
testing was quite trivial (8 CPU machine):

mount -t cgroup -o cpuset none /mnt/cgroup
mkdir /mnt/cgroup/a
echo 0-5 >  /mnt/cgroup/a/cpuset.cpus
echo 0 > /mnt/cgroup/a/cpuset.mems
for i in `cat /mnt/cgroup/tasks`; do echo $i > /mnt/cgroup/a/tasks; done
[only kernel threads will stay in the root cgroup]
mkdir /mnt/cgroup/b
echo 6,7 >  /mnt/cgroup/a/cpuset.cpus
echo 0 > /mnt/cgroup/a/cpuset.mems
[no task in that group so CPU6,7 should be idle most of the time]

Without the last patch I can see unchanged values for CPU[67] taking up to
several seconds.

This patch:

Get rid of semicolon so that those expressions can be used also somewhere
else than just in an assignment.

fb_set_suspend() must be called with the console semaphore held, which
means the code path coming in here will first take the console_lock() and
then call lock_fb_info().

However several framebuffer ioctl commands acquire these locks in reverse
order (lock_fb_info() and then console_lock()).  This gives rise to
potential AB-BA deadlock.

Fix this by changing the order of acquisition in the ioctl commands that
make use of console_lock().

The current interrupt traces from irq_handler_entry and irq_handler_exit
provide when an interrupt is handled.  They provide good data about when
the system has switched to kernel space and how it affects the currently
running processes.

There are some IRQ vectors which trigger the system into kernel space,
which are not handled in generic IRQ handlers.  Tracing such events gives
us the information about IRQ interaction with other system events.

The trace also tells where the system is spending its time.  We want to
know which cores are handling interrupts and how they are affecting other
processes in the system.  Also, the trace provides information about when
the cores are idle and which interrupts are changing that state.

The following patch adds the event definition and trace instrumentation
for interrupt vectors.  For x86, a lookup table is provided to print out
readable IRQ vector names.  The template can be used to provide interrupt
vector lookup tables on other architectures.

This new driver replaces the old PCEngines Alix 2/3 LED driver with a new
driver that controls the LEDs through the leds-gpio driver.  The old
driver accessed GPIOs directly, which created a conflict and prevented
also loading the cs5535-gpio driver to read other GPIOs on the Alix board.
 With this new driver, we hook into leds-gpio which in turn uses GPIO to
control the LEDs and therefore it's possible to control both the LEDs and
access onboard GPIOs

Driver is moved to platform/geode and any other geode initialisation
modules should move here also.

This driver is inspired by leds-net5501.c by Alessandro Zummo.

Ideally, leds-net5501.c should also be moved to platform/geode.
Additionally the driver relies on parts of the patch: 7f131cf3ed ("leds:
leds-alix2c - take port address from MSR) by Daniel Mack to perform
detection of the Alix board.

This is both unexpected for userspace and makes readlink/readlinkat
inconsistant with all other interfaces; and inconsistant with our stated

As the readlinkat call does not have a flags parameter we cannot use the
