Subject[patch] Real-Time Preemption, -RT-2.6.9-mm1-U10.2

i have released the -U10.2 Real-Time Preemption patch, which can be
downloaded from:

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

this is a fixes-only release.

Changes since -U10:

- fixed a big bug present ever since: the BKL got dropped when a
spinlock-mutex was acquired and it scheduled away. This reduced the
locking efficiency of the BKL. A number of outstanding problems could
be affected, in particular this should fix the tty locking breakage
reported by Alexander Batyrshin and Adam Heath. UP and SMP systems
are affected too, with SMP systems having a higher chance to trigger
this condition.

- tulip.c breakage fix from Thomas Gleixner

- tg3 and 3c59x fixes.

- made the hardirq threads SCHED_FIFO by default. They get priorities
between 25 and 50, depending on the irq #. (this is pretty random but
i found no better scheme.) Made the softirq thread SCHED_FIFO by
default as well, albeit this probably will have to change. These
changes should make it easier to debug a hung system.

to create a -U10.2 tree from scratch, the patching order is:

http://kernel.org/pub/linux/kernel/v2.6/linux-2.6.9.tar.bz2
+ http://kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.9/2.6.9-mm1/2.6.9-mm1.bz2
+ http://redhat.com/~mingo/realtime-preempt/realtime-preempt-2.6.9-mm1-U10.2
