Requests that triggers flushing volatile writeback cache to disk (barriers)
have significant effect to overall performance.
Block layer has sophisticated engine for combining several flush requests
into one. But there is no statistics for actual flushes executed by disk.
Requests which trigger flushes usually are barriers - zero-size writes.
This patch adds two iostat counters into /sys/class/block/$dev/stat and
/proc/diskstats - count of completed flush requests and their total time.

In addition to using vcsi regulator for the display, looks like droid4 is
using vcsi regulator to trigger off mode internally with the PMIC firmware
when the SoC enters deeper idle states. This is configured in the Motorola
Mapphone Linux kernel sources as "zerov_regulator".
As we currently don't support off mode during idle for omap4, we must
prevent vcsi from being disabled when the display is blanked to prevent
the PMIC change to off mode. Otherwise the device will hang on entering
idle when the display is blanked.
Before commit 089b3f61ec ("regulator: core: Let boot-on regulators be
powered off"), the boot-on regulators never got disabled like they should
and vcsi did not get turned off on idle.
Let's fix the issue by setting vcsi to always-on for now. Later on we may
want to claim the vcsi regulator also in the PM code if needed.

Add kernel AUX area sampling definitions, which brings perf_event.h into
line with the kernel version.
New sample type PERF_SAMPLE_AUX requests a sample of the AUX area
buffer. New perf_event_attr member 'aux_sample_size' specifies the
desired size of the sample.
Also add support for parsing samples containing AUX area data i.e.
PERF_SAMPLE_AUX.
Committer notes:
I squashed the first two patches in this series to avoid breaking
automatic bisection, i.e. after applying only the original first patch
in this series we would have:
# perf test -v parsing
26: Sample parsing :
--- start ---
test child forked, pid 17018
sample format has changed, some new PERF_SAMPLE_ bit was introduced - test needs updating
test child finished with -1
---- end ----

The per-SoC devtype structures can contain their own callbacks that
overwrite mpc8xxx_gpio_devtype_default.
The clear intention is that mpc8xxx_irq_set_type is used in case the SoC
does not specify a more specific callback. But what happens is that if
the SoC doesn't specify one, its .irq_set_type is de-facto NULL, and
this overwrites mpc8xxx_irq_set_type to a no-op. This means that the
following SoCs are affected:
- fsl,mpc8572-gpio
- fsl,ls1028a-gpio
- fsl,ls1088a-gpio
On these boards, the irq_set_type does exactly nothing, and the GPIO
controller keeps its GPICR register in the hardware-default state. On
the LS1028A, that is ACTIVE_BOTH, which means 2 interrupts are raised
even if the IRQ client requests LEVEL_HIGH. Another implication is that
the IRQs are not checked (e.g. level-triggered interrupts are not
rejected, although they are not supported).
