up->irq was just duplicating up->port.irq so
delete the former and only use the latter.  We
were not initializing up->port.irq so this would
cause port shutdown crashes when synchronize_irq()
was called.

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.

- 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

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.
