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.

- 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

 - 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

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.
