Kernel source files need not include explicitly
because the top Makefile forces to include it with:-include $(srctree)/include/linux/kconfig.h
This commit removes explicit includes except the following:
* arch/s390/include/asm/facilities_src.h
* tools/testing/radix-tree/linux/kernel.hThese two are used for host programs.

The probe functions in this driver is not exported or declared
so make it static to fix the following warning:drivers/irqchip/irq-brcmstb-l2.c:115:12: warning: symbol 'brcmstb_l2_intc_of_init' was not declared. Should it be static?

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!Signed-off-by: Thomas Gleixner

The irq argument of most interrupt flow handlers is unused or merily
used instead of a local variable. The handlers which need the irq

Chained irq handlers usually set up handler data as well. We now have
a function to set both under irq_desc->lock. Replace the two calls
with one.Search and conversion was done with coccinelle:

The IRQCHIP_DECLARE macro moved to to 'include/linux/irqchip.h', so
the local irqchip.h became an empty shell, which solely includes
include/linux/irqchip.hInclude the global header in all irqchip drivers instead of the local
header, so we can remove it.Signed-off-by: Joel Porquet

Wakeable interrupts might be pending at boot/init time, because wakeup
interrupts might have triggered a resume from S5. So don't clear such
wakeups.This means that any driver which requests a wakeable interrupt bit
should be prepared to handle an interrupt as soon as they call
request_irq(). (This is technically already the correct development
practice, but some drivers probably expect not to receive interrupts
until they have performed some I/O.)Signed-off-by: Brian Norris

Pull irq core updates from Thomas Gleixner:
"This is the first (boring) part of irq updates:- support for big endian I/O accessors in the generic irq chip
- cleanup of brcmstb/bcm7120 drivers so they can be reused for non
ARM SoCs- the usual pile of fixes and updates for the various ARM irq chips"

This effectively converts the __raw_ accessors to the non-__raw_
equivalents. To handle BE, we pass IRQ_GC_BE_IO, similar to what was
done in irq-bcm7120-l2.c.Since irq_reg_writel now takes an irq_chip_generic argument, writel must
be used for the initial hardware reset in the probe function. But that
operation never needs endian swapping, so it's probably not a big deal.Signed-off-by: Kevin Cernekee
