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.

- Add definition for SActive register
- Add most interrupt sources to default interrupt mask
- Write low 32 bits of FIS address to PxFB, where they belong
- Set command active bit in PxSACT before setting command issue bit in PxCI
- Announce Sub Class Code in driver info message [IDE, SATA or RAID]

and additionally, from me [jgarzik]:
- ignore ports-implemented bitmap for now; it's a write-only register

That's "cpu", not "cpy".

 - Add the PARISC tag (Thibaut Varene)
 - Mark some existing PA-RISC specific entries with it (Thibaut Varene)
 - Document pdcchassis (Thibaut Varene)

 - Fix "sti= parameter ignored by stifb" bug (Stuart Brady)
 - Fix the STI crash with HCRX-24 in 32bpp mode (Helge Deller)

100% cosmetic:  rename various symbols with 'sata' in them to 'ata',
in preparation for addition of support for a PATA controller.

This patch adds a few memory barriers, cleans up a little bit the
use of the "status" field in the rx & tx routines, and adds probing
for the external PHY to the driver.

This patch does an indentation fix to amd8111e_rx_poll() which was
incorrectly shifting left in the middle of a while() loop, thus
rendering the function difficult to read. There is no actual code
change.

Since bit 0 is only set when the MM is mapped onto the CPU, we can use
this rather than comparing the MM pointer with current->active_mm.
This simplifies the inline cache flushing and tlb code.

Christoph suggests letting the compiler choose.  No real compelling reason
to inline anyhow.  I had some vmlinux size numbers suggesting inline was
better, but re-running them on newer kernel is giving different results,
favoring uninline.  Best let compiler choose.  Un-inline __sigqueue_alloc.
