bd0b9ac405 genirq: Remove irq argument from irq flow handlers 
Most interrupt flow handlers do not use the irq argument. Those few
which use it can retrieve the irq number from the irq descriptor.

Remove the argument.

Search and replace was done with coccinelle and some extra helper
scripts around it. Thanks to Julia for her help!

e8d36d5dbb ARM: kill off set_irq_flags usage 
set_irq_flags is ARM specific with custom flags which have genirq
equivalents. Convert drivers to use the genirq interfaces directly, so we
can kill off set_irq_flags. The translation of flags is as follows:

IRQF_VALID -> !IRQ_NOREQUEST
IRQF_PROBE -> !IRQ_NOPROBE
IRQF_NOAUTOEN -> IRQ_NOAUTOEN

For IRQs managed by an irqdomain, the irqdomain core code handles clearing
and setting IRQ_NOREQUEST already, so there is no need to do this in
.map() functions and we can simply remove the set_irq_flags calls. Some
users also modify IRQ_NOPROBE and this has been maintained although it
is not clear that is really needed. There appears to be a great deal of
blind copy and paste of this code.

7f77c5c39d ARM: gemini: Fix race in installing GPIO chained IRQ handler 
The gemini code was installing its chained interrupt handler (which
enables the interrupt) before it was setting its data, which is bad if
the IRQ was previously pending.  Avoid this problem by converting it to
irq_set_chained_handler_and_data().

85649711a8 ARM: gemini: delete <mach/gpio.h> 
The Gemini has no need of a <mach/gpio.h> header as this is only
used by the machine-local gpio.c gpiochip driver, which is also
only using the irq_to_gpio() macro. Delete the file, move the single
macro into the driver and remove the NEED_MACH_GPIO_H flag.

662146b155 ARM: gemini: get platform to build again 
There is no defconfig file for gemini, which has lead to a lot
of bitrot. This makes the broken board files, the gpio implementation
and the reset logic work again, and fixes the build warnings
that got introduced with the changes to the readl/writel prototypes.
