In m68k/m68knommu assembly files, the same value is called sometimes
PT_OFF_VECTOR, but more frequently PT_OFF_FORMATVEC. Standardize
name to PT_OFF_FORMATVEC.

m68k{nommu}/asm-offsets.c define many constants which are not used
anymore anywhere; remove IRQ_DEVID, IRQ_HANDLER, IRQ_NEXT, STAT_IRQ,
TASK_ACTIVE_MM, TASK_BLOCKED, TASK_FLAGS, TASK_PTRACE, TASK_STATE,
TASK_THREAD_INFO, TI_CPU, TI_EXECDOMAIN and TI_TASK.

Fix the IRQ flag handling naming. In linux/irqflags.h under one configuration,
it maps:
local_irq_enable() -> raw_local_irq_enable()
local_irq_disable() -> raw_local_irq_disable()
local_irq_save() -> raw_local_irq_save()
...
and under the other configuration, it maps:
raw_local_irq_enable() -> local_irq_enable()
raw_local_irq_disable() -> local_irq_disable()
raw_local_irq_save() -> local_irq_save()
...
This is quite confusing. There should be one set of names expected of the
arch, and this should be wrapped to give another set of names that are expected
by users of this facility.
Change this to have the arch provide:
flags = arch_local_save_flags()
flags = arch_local_irq_save()
arch_local_irq_restore(flags)
arch_local_irq_disable()
arch_local_irq_enable()
arch_irqs_disabled_flags(flags)
arch_irqs_disabled()
arch_safe_halt()
Then linux/irqflags.h wraps these to provide:
raw_local_save_flags(flags)
raw_local_irq_save(flags)
raw_local_irq_restore(flags)
raw_local_irq_disable()
raw_local_irq_enable()
raw_irqs_disabled_flags(flags)
raw_irqs_disabled()
raw_safe_halt()
with type checking on the flags 'arguments', and then wraps those to provide:
local_save_flags(flags)
local_irq_save(flags)
local_irq_restore(flags)
local_irq_disable()
local_irq_enable()
irqs_disabled_flags(flags)
irqs_disabled()
safe_halt()
with tracing included if enabled.
The arch functions can now all be inline functions rather than some of them
having to be macros.

Commit f159ee782990aacb5494738c98f13a2aa61dbb4a ("locking,
m68k/asm-offsets: Rename pt_regs offset defines") breaks the
m68knommu entry code that relies on these define names.
Fix the files to match the new define names.

As the subject says this patch adds the support for kernel preemption
on m68knommu Coldfire. I thing the same changes could be applied to
68360 & 68328 but since I don't have the HW for testing, I don't touch it.

Recently a few direct accesses to the thread_info in the task structure snuck
back, so this wraps them with the appropriate wrapper.

Move some of the m68knommu platform specific irq core support
to its own header, irqnode.h. Having it in asm-m68knommu/irq.h
causes some build pain, since it is included in a number of
common code places (and not all the required definitions will
be included at these places).

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!
