1. define PXA_GPIO_IRQ_BASE to be right after the internal IRQs,
and define PXA_GPIO_IRQ_NUM to be 128 for all PXA2xx variants
2. make the code specific to the high IRQ numbers (32..64) to be
PXA27x specific
3. add a function pxa_init_irq_high() to initialize the internal
high IRQ chip, the invoke of this function could be moved to
PXA27x specific initialization code

1. PXA_IRQ_SKIP is defined to be 7 on PXA25x so that the first IRQ
starts from zero. This makes IRQ numbering inconsistent between
PXA25x and PXA27x. Remove this macro so that the same IRQ_XXXXX
definition has the same value on both PXA25x and PXA27x.
2. make IRQ_SSP3..IRQ_PWRI2C valid only if PXA27x is defined, this
avoids unintentional use of these macros on PXA25x

Lots of places in arch/arm were needlessly including linux/ptrace.h,
resumably because we used to pass a struct pt_regs to interrupt
handlers. Now that we don't, all these ptrace.h includes are
redundant.

Untested, but this should fix up the bulk of the totally mechanical
issues, and should make the actual detail fixing easier.

Patch from David Brownell
ARM genirq cleanups/updates:
- Start switching platforms to newer APIs
* use "irq_chip" name, not "irqchip"
* providing irq_chip.name
- Show irq_chip.name in /proc/interrupts, like on x86.
This update a bit more than half of the ARM code. The irq_chip.name
values were chosen to match docs (if I have them) or be otherwise
obvious ("FPGA", "CPLD", or matching the code).

Patch from Guennadi Liakhovetski
Currently probe_irq_on() on PXA will silently reconfigure all output GPIOs, that are not configured as alternate functions, for input. Avoid that. Upon CPU reset all GPIOs are configured as inputs, so, if a GPIO is configured as output, it has been done so intentionally.

This is part of Thomas Gleixner's generic IRQ patch, which converts
ARM to use the generic IRQ subsystem. Here, we wrap calls to
desc->handler() in an inline function, desc_handle_irq(). This
reduces the size of Thomas' patch since the changes become more
localised.

This is part of Thomas Gleixner's generic IRQ patch, which converts
ARM to use the generic IRQ subsystem. Here, we rename two of the
irq_chip methods - wake becomes set_wake, and type becomes set_type.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
