The master abort check in ixp2000_pci_read_config() recently started
failing due to the compiler optimising out the read access following
the clearing of pci_master_aborts. Mark pci_master_aborts volatile to
force the compiler to reload it on every use.

This patch includes a number of small changes for integrating the
AT91SAM9261 and AT91SAM0260 support.
* Can only select support for one AT91 processor at a time.
* Remove most of the remaining static memory mapping for the
AT91RM9200.
* Reserve 1Mb of memory below the IO for mapping the internal SRAM
and any custom board-specific devices (ie, FPGA).
* The SAM9260 has more serial ports, so increase the maximum to 7.
* Define the standard chipselect addresses, and define other
addresses relative to those.
* CLOCK_TICK_RATE is different on the SAM926x's.

Remove ARM local cache of 4 struct thread_info.
Can cause oops under certain circumstances.
Russell indicated the original optimization was
required on older kernels to avoid thread starvation
on memory fragmentation, but may no longer be
required. I've updated the patch to 19rc4 and
ensured no <config.h> dain-bramage slipped in this
time (sorry about that).
Original description follows:
I was given some test results which pointed to an
Oops in alloc_thread_info (happened 2x), and after
looking at the code, I see that ARM has its own
local cache of 4 struct thread_info. There wasn't
any clear (to me) synchronization between the
alloc_thread_info and the free_thread_info.
I looked over the other arch, and they all simply
allocate them on an as needed basis, so I simplified
the ARM to do the same, based on the other arch
(e.g. PPC) and the folks doing the testing have
indicated that this fixed the oops.

show_mem() was not correctly handling holes in the memory
map. It was treating the freed sections of the map as
though they contained valid struct page entries. This
could cause incorrect debugging output or even a kernel
panic.
This patch keeps the struct meminfo around after system
initialization so that show_mem() can use it when
scanning memory. show_mem() now walks over each bank
of each online node, rather than assuming that each node
contains a single contiguous bank.

This is a rework of the ixp4xx irq_chip implementation. The use of
two irq_chip structures and potentially switching between them is a
violation of the intended use of the IRQ framework. The current
implementation does not work with current in-kernel spinlock debugging
or lockdep due to lock recursion problems caused by calling
set_irq_chip/handler from within the chip's set_irq_type().
This patch goes back to using one irq_chip structure and handling the
differences between edge/level, normal/GPIO interrupts inside the
ack/mask/unmask routines themselves.
