on early revision of EXYNOS4 SoCs. All UniversalC210 boards are

ARM / mach-shmobile: Use preset_lpj with calibrate_delay()
Update the mach-shmobile shared delay calibration code for late
timers. All existing in-tree non-DT socs are however using early
timers today and they are unaffected by this change.
The patch modifies shmobile_setup_delay() from using lpj_fine
to preset_lpj. This change allows us to preset the worst case
loops-per-jiffy value to all CPU cores on the system.
The old code which made use of lpj_fine did not affect the
secondary CPU cores which made it impossible to boot on SMP
without early timers.

gpio: pch9: Use proper flow type handlers
Jean-Francois Dagenais reported:
Configuring a gpio pin with the gpio-pch driver with
"IRQF_TRIGGER_LOW | IRQF_ONESHOT" generates an interrupt storm for
threaded ISR until the ISR thread actually gets to physically clear
the interrupt on the triggering chip!! The immediate observable
symptom is the high CPU usage for my ISR thread task and the
interrupt count in /proc/interrupts incrementing radically.
The driver is wrong in several ways:
1) Using handle_simple_irq() does not provide proper flow control
handling. In the case of oneshot threaded handlers for the
demultiplexed interrupts this results in an interrupt storm because
the simple handler does not deal with masking/unmasking. Even
without threaded oneshot handlers an interrupt storm for level type
interrupts can easily be triggered when the interrupt is disabled
and the interrupt line is activated from the device.
2) Acknowlegding the demultiplexed interrupt before calling the
handler is wrong for level type interrupts.
3) The set_type function unconditionally enables the interrupt. It's
supposed to set the type and nothing else. The unmasking is done by
the core code.
Move the acknowledge code into a separate function and add it to the
demux irqchip callbacks.
Remove the unconditional enabling from the set_type() callback and set
the proper flow handlers depending on the selected type (level/edge).

really makes senses to go ahead and drop this extra cruft to avoid any

powerpc/irq: Fix another case of lazy IRQ state getting out of sync
So we have another case of paca->irq_happened getting out of
sync with the HW irq state. This can happen when a perfmon
interrupt occurs while soft disabled, as it will return to a
soft disabled but hard enabled context while leaving a stale
PACA_IRQ_HARD_DIS flag set.
This patch fixes it, and also adds a test for the condition
of those flags being out of sync in arch_local_irq_restore()
when CONFIG_TRACE_IRQFLAGS is enabled.
This helps catching those gremlins faster (and so far I
can't seem see any anymore, so that's good news).
