Commit 8dc7a9c8 ("blackfin: Add export.h to files using
EXPORT_SYMBOL/THIS_MODULE") inserted some of the include statements into
sections protected by an unrelated #if CONFIG_... statement. This can cause,
depending on the configuration used, warnings like this one:

	arch/blackfin/mach-bf537/boards/stamp.c:2940: warning: data definition has no type or storage class
	arch/blackfin/mach-bf537/boards/stamp.c:2940: warning: type defaults to ‘int’ in declaration of ‘EXPORT_SYMBOL’
	arch/blackfin/mach-bf537/boards/stamp.c:2940: warning: parameter names (without types) in function declaration

This patch fixes it by moving the includes out of the #if protected sections.

IRQF_SHARED is not part of the IORESOURCE_IRQ bits. It's expressed by
IORESOURCE_IRQ_SHAREABLE.

IORESOURCE_IRQ_HIGHEDGE and IRQF_TRIGGER_HIGH are contradicting
values, an interrupt can hardly be configured for both level and edge
at the same time. This was introduced in commit 45138439(Blackfin
arch: flash memory map and dm9000 resources updating) of course

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.

Although they are marked inline, gcc may still make a function out of

tracer. This can cause undesirable results (kernel panic, triple faults,

The current save logic used in hibernation is to do a MMR load (base +
offset) into a register, and then push that onto the stack.  Then when
restoring, pop off the stack into a register followed by a MMR store
(base + offset).  These use plenty of 32bit insns rather than 16bit,
are pretty long winded, and full of pipeline bubbles.

So, by taking advantage of MMRs that are contiguous, the multi-register
push/pop insn, and register abuse, we can shrink this code considerably.

When saving, the new logic does a lot of loads into the data and pointer
registers before executing a single multi-register push insn.  Then when
restoring, we do a single multi-register pop insn followed by a lot of
stores.  Overall, this allows us to cut the insn count by ~30%, the code
size by ~45%, and drastically reduce the register hazards that trigger
bubbles in the pipeline.

EVT0 is for emulation, EVT1 is for reset, and EVT4 is the "global int

core-memory scratch, but that's just crazy talk).
