HP300 DIO bus updates from Kars de Jong:
  - Removed kludges for internal HPIB, no need to handle it as a DIO device
  - Removed dio_scodetoviraddr() and introduced dio_scodetophysaddr() instead,
    to be able to support DIO-II
  - Removed trailing white space
  - Changed error return code of dio_find() from 0 to -1, since select code 0
    is a valid select code

 - Fix SMP f_list corruption problem.

   This was rather subtle.  It turns out that gcc was doing a small
   amount of reordering around the file_lock because it doesn't see our
   spinlock implementation as being a barrier.  To fix this I

   - Added the appropriate barriers to all the spinlocks.
   - Removed the atomic opencoded spinlock and redid it as a proper one.

   SMP now seems stable on a 2xA500 and has survived a 10 hour 35 loop

   usually fell over in the first loop).

Patch from Liam Girdwood

This patch adds support the PXA250, 255, 26x and 27x SSP ports. It
provides a generic core for simple IO-based SSP applications and allows
easy port setup for DMA access.

Depends on register definitions in patch 2084/1

build error. Since the "extern const UQItype __clz_tab[]" definition

 endian

Patch from Lennert Buytenhek

When you issue the mnfd opcode to negate a double, nwfpe is supposed
to flip the most significant bit of your double, which is the sign
bit.  However, on big endian systems, it ended up flipping the most
significant bit of the least significant sub-u32, which is one of the
mantissa bits.

On my system this was manifesting itself as sed regression tests
failing, and ntpd/ntpdate consistently adjusting the system clock
into the wrong direction.

In pretty much all of NWFPE, doubles are stored in u64s and
manipulations on those doubles are done by using u64 bitops.  But
for negation and fabs() it was poking into one of the sub-u32s
directly instead of XORing the u64 with 0x8000000000000000 resp.
ANDing with 0x7fffffffffffffff.

Since on big-endian, 'native u64 order' means that the most
significant byte (containing bits 63-56) is kept at the lowest
byte address, the sign bit is the MSB of the first sub-u32,
instead of the MSB of the second one as is the case on little
endian.

 conditional on ARCH_H720X

Patch from G N Barzini

Currently under "System Type" you are always offered "h720x
Implementations" regardless of the system type selected. The fix for
this in the other Kconfig files seems to be enclose their contents
conditional in 'if ARCH_FOO'/'endif'. This patch does that.

Patch from Ben Dooks

This patch fixes the following problems:

- panic() in reset should be warning print, so that the
  system can then be soft-reset if this ever happens

- arch_idle() can now be over-ridden for purposes of
  implementing dyanmic voltage scaling (DVS) or any
  other form of idling

- Add iomd, keyboard and acornfb platform devices.
- Convert rpckbd to use centrally registered platform device.
- Convert acornfb to use a platform device.

m68k used to do this by hand, but it really ends up being needed
for any environment that does cross-builds, so just do it
unconditionally.

This should mean that you never need to cross-build sparse or
have any other hacks for checking a cross-built environment.

This way you can do a checking run on UP too - even if the
locks don't actually _matter_, they should still be right,
I'd hope.

In particular, a function that is called with a lock held, and
releases it only to re-acquire it needs to be annotated as such,
since otherwise sparse will complain about an unexpected unlock,
even though "globally" the lock is constant over the call.

This annotates the scheduler routines for locking, telling
what locks a function releases or acquires, allowing sparse
to check the lock usage (and documenting it at the same time).

and atomic_dec_and_lock.

This means that we now have all of the spinlock context counting
infrastructure in place, and you can check-compile the kernel with 
sparse -Wcontext.

We rename the actual architecture-specific low-level implementation
to have a prepended underscore: "_atomic_dec_and_lock()".

This extra macro indirection is so that we can make the macro do
the lock context counting. That will be the next patch.
