SubjectLinux-2.5.28

The most fundamental part of this has already been discussed a lot and
posted to the kernel list, including a lot of fixes (all hopefully
integrated). That's obviously the removal of the global irq lock. In the
short term (famous last words) that breaks a number of SMP configurations,
but fixing them should not be horribly hard.

A lot of other stuff here too - the regular USB updates, fbdev updates,
m68k and ppc64 updates, IDE fix, and a sync-up with Al. Serial lawyer all
shook up (the irq lock kind of forced that one, but it's certainly been
pending long enough..)

Go wild,

Linus

The original fix sent to Ingo for stop_tx didn't take account that
the start_tx and stop_tx methods can be called from the device
specific code under the port spinlock. Consequently, we move the
spinlock to the callers of these methods. Documentation updated to
reflect the change.
