The irq_desc array consumes quite a lot of space, and for systems
that don't need or can't have 512 irqs it's just wasted space.
The first 16 are reserved for ISA, so the minimum of 32 is really
16 - and no one has asked for more than 512 so leave that as the
maximum.

So at least you can see what kernel you're booting if you die
before the kernel prints it mid-way through start_kernel().

There's no way for us to express to firmware that we want a
discontiguous, or non-zero based, range of MSI-X entries. So we
must reject such requests.

The Axon MSI driver depends on more than just PCI_MSI, so add a
Kconfig fragment for it. Fixes randconfig build failures.

The RPA PCI hotplug driver calls EEH routines, so should depend on
EEH. Also PPC_PSERIES implies PPC64, so remove that.

Generic code needs PAGE_KERNEL_EXEC:
mm/vmalloc.c:
#ifndef PAGE_KERNEL_EXEC
# define PAGE_KERNEL_EXEC PAGE_KERNEL
#endif
Not having it breaks modules because we don't map the text executable.

Most of the code enabled by these options is __init, and it's much
more useful to actually run the tests.

sometimes be overly tolerant of broken device trees,
which is probably what happened.
It assumes a missing ranges == empty ranges, which means 1:1. See the
comment in of_translate_one(). And thank Apple ;)

a virtual irq number.
of_irq_to_resource() is doing the remapping for you.
You can turn on CONFIG_VIRQ_DEBUG and you'll get a file in debugfs that
