[ Upstream commit 27eebb60357ed5aa6659442f92907c0f7368d6ae ]
If the 'brcm,irq-can-wake' property is specified, make sure we also
enable the corresponding parent interrupt we are attached to.

[ Upstream commit 0702bc4d2fe793018ad9aa0eb14bff7f526c4095 ]
When compiling bmips with SMP disabled, the build fails with:
drivers/irqchip/irq-bcm7038-l1.o: In function `bcm7038_l1_cpu_offline':
drivers/irqchip/irq-bcm7038-l1.c:242: undefined reference to `irq_set_affinity_locked'
make[5]: *** [vmlinux] Error 1
Fix this by adding and setting bcm7038_l1_cpu_offline only when actually
compiling for SMP. It wouldn't have been used anyway, as it requires
CPU_HOTPLUG, which in turn requires SMP.
Fixes: 34c535793bcb ("irqchip/bcm7038-l1: Implement irq_cpu_offline() callback")

Kernel source files need not include <linux/kconfig.h> 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.h
These two are used for host programs.

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!

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:

This is the main peripheral IRQ controller on the BCM7xxx MIPS chips;
it has the following characteristics:
- 64 to 160+ level IRQs
- Atomic set/clear registers
- Reasonably predictable register layout (N status words, then N
mask status words, then N mask set words, then N mask clear words)
- SMP affinity supported on most systems
- Typically connected to MIPS IRQ 2,3,2,3 on CPUs 0,1,2,3
This driver registers one IRQ domain and one IRQ chip to cover all
instances of the block. Up to 4 instances of the block may appear, as
it supports 4-way IRQ affinity on BCM7435.
The same block exists on the ARM BCM7xxx chips, but typically the ARM GIC
is used instead. So this driver is primarily intended for MIPS STB chips.
