The patch below makes some needlessly global code static.

The most interesting part is that dquot_cachep can become static, since 
it isn't used outside of dquot.c .

When a thread stops for ptrace exit tracing, it cannot be resumed by
SIGKILL.  Once PF_EXITING is set, SIGKILL will not cause a wakeup from stop
(see wants_signal in kernel/signal.c).  This patch moves the ptrace stop
for exit tracing before the setting of PF_EXITING.

Upon reevaluation we think it is indeed safe to permit the race between
a ptrace call and the traced thread waking up, as long as it will never
get back to user mode.  This patch makes SIGKILL wake up threads in
TASK_TRACED.  That alone resolves most of the deadlock issues that
became possible with the introduction of TASK_TRACED, getting us back to
the killing behavior of 2.6.8 and before. 

This patch also further cleans up ptrace detaching, so that threads are
left in TASK_STOPPED only if a job control stop is actually in effect,
and otherwise resume.  This removes the past nuisances requiring a
SIGCONT to resume a thread even when it had a pending SIGKILL.

Patch from Richard Purdie

The Sharp SL-C7xx series of PDAs (Corgi, Shepherd, Husky) don't set
the machine type upon startup. Fixing this isn't possible as the
devices have been produced and the bootloaders are in ROM. 

This header code detects the differences between them and sets the
machine type accordingly. By doing this one kernel can support the
series of PXA25x machines.

The code also detects Poodle (Sharp SL-5600) which is also a PXA25x
device allowing a common kernel to support that device as well. (The
base machine code is under development for this device).

Patch from Ben Dooks

If we read the INTPEND register and get the wrong
result (details below) then it looks like a possible
loop to go back and re-read it after calculating
the possible correct value for it.

It seems that the INTPEND register, which should
show the unique number of the interrupt that we
need to handle. However, it seems that this register
can show the wrong interrupt under certain conditions.

Shannon's research shows that it is very possible that
the occurence of an external interrupt can end up
merging with the base interrupt number, causing
the wrong result in the register.

This patch also fixes the end position of the #ifdef
block and ensures as many registers as possible are
stacked before calling printk() for debug.

The __ptrace_unlink code that checks for TASK_TRACED fixed the problem of a
thread being left in TASK_TRACED when no longer being ptraced. 

However, an oversight in the original fix made it fail to handle the
case where the child is ptraced by its real parent.

Fixed thus.

As Alan says:

  "The '1.8' version is for the Moxa mxser driver.  Moxa haven't
   released any 2.6 driver for the ancient 'smartio' hardware"

so the smartio driver stil remains valid.

The grows-up and grows-down cases had all the same issues, but
differered in the details. Additionlly, historical evolution of
the tests had caused the result to be pretty unreadable with some
rather long and complex conditionals.

Fix it all up in a more readable helper function.

This also adds the missing RLIMIT_MEMLOCK test.

We use a non-atomic kmap() to clear the page, which cannot be
used from atomic contexts.

It doesn't do the virtual cache synchronization that clear_user_highpage()
does.

Pointed out by Hugh Dickins.

This not only makes sense, it fixes DEBUG_PAGEALLOC together with
the new page zeroing, since we must map the page before we zero it.

As per Chris Wright.
