The patch removes all the uses of cpu_is_mx1(). Instead, it uses
the .id_table of platform_driver to distinguish the uart device type,
IMX1_UART and IMX21_UART. The IMX21_UART type runs on all i.mx
except i.mx1.
A couple of !cpu_is_mx1 logic gets turned into is_imx21_uart,
as the codes wrapped there are really IMX21 type uart specific.
It also removes macro MX1_UCR3_REF25 and MX1_UCR3_REF30 which are
not used anywhere.

After changing all consumers of atomics to include <linux/atomic.h>, we
ran into some compile time errors due to this dependency chain:
linux/atomic.h
-> asm/atomic.h
-> asm-generic/atomic-long.h
where atomic-long.h could use funcs defined later in linux/atomic.h
without a prototype. This patches moves the code that includes
asm-generic/atomic*.h to linux/atomic.h.
Archs that need <asm-generic/atomic64.h> need to select
CONFIG_GENERIC_ATOMIC64 from now on (some of them used to include it
unconditionally).
Compile tested on i386 and x86_64 with allnoconfig.

Building kernel 3.0 for an n2100 (plat-iop) results in:

Nothing here depends on the layout of pt_regs or task_struct, so this
can be fixed by adding forward struct declarations to asm/traps.h.

I've got hands on one ts-7300 board, which is equiped with 128MB RAM in two
64MB memory chips, so it's 16 banks/8MB each. Without this patch, the bootmem
init code complains about small NR_BANKS number and only lower 64MB is
accessible.

Commit 66a625a (ARM: mm: proc-macros: Add generic proc/cache/tlb struct
definition macros) introduced build errors when PM_SLEEP is not enabled.
The per-CPU do_suspend/do_resume functions are defined via the
preprocessor to constant 0. However, the macros which use these were
converted to assembly, resulting in undefined references to these
functions. Fix that by moving the ! ifdef section into proc-macros.S
and deleting it from all effected proc-*.S files.

Previously we just assumed there were CONFIG_NR_CPUS cpus present in

[arnd: clarified patch title]

Our selection of interrupts to consider for IRQ migration is sub-
standard. We were potentially including per-CPU interrupts in our
migration strategy, but omitting chained interrupts. This caused
some interrupts to remain on a downed CPU.
We were also trying to migrate interrupts which were not migratable,
resulting in an OOPS.
Instead, iterate over all interrupts, skipping per-CPU interrupts
or interrupts whose affinity does not include the downed CPU, and
attempt to set the affinity for every one else if their chip
implements irq_set_affinity().

Now that the GIC takes care of selecting a target interrupt from the
affinity mask, we don't need all this complexity in the core code
anymore. Just detect when we need to break affinity.

The irq_set_affinity() method can be called with masks which include
offline CPUs. This allows offline CPUs to have interrupts routed to
them by writing to /proc/irq/*/smp_affinity after hotplug has taken
a CPU offline. Fix this by ensuring that we select a target CPU
present in both the required affinity and the online CPU mask.
Ensure that we return IRQ_SET_MASK_OK (which happens to be 0) on
success to ensure generic code copies the new mask into the irq_data
structure.
