Subject[patch] Real-Time Preemption, -RT-2.6.9-rc4-mm1-U9

i have released the -U9 Real-Time Preemption patch, which can be
downloaded from:

http://redhat.com/~mingo/realtime-preempt/

this too is a fixes-only release. It includes more driver fixes and
improvements from Thomas Gleixner.

Changes since -U8.1:

- USB semaphore->completion conversion from Thomas Gleixner

- netconsole fixes from Michal Schmidt

- fbcon fixes

- added counted semaphores, this is now used by firewire, XFS and ACPI.
This could fix the firewire breakage - but testing would be welcome.

- PREEMPT_ACTIVE irqs-enabled critical path removal.

- fixed irqs-off raw spinlock primitives on UP: they enabled irqs
before enabling preemption, creating a window for an interrupt to
slip in and increase the critical path.

- made the deadlock detector not crash the current process - it will
just hang. This produces far nicer log output while still not
endangering stability. Also, fixed a bug in the detector that happens
if the trace buffer overflows.

- made the atomic-counter-underflow detector non-fatal as well, for the
same reasons.

to create a -U9 tree from scratch, the patching order is:
