        ftp://ftp.kernel.org/pub/linux/kernel/people/rml/sched/ingo-O1/sched-O1-rml-2.4.19-rc1-1.patch

and mirrors. Aside from the resync to 2.4.19-rc1, the following changes
are new since the last release (most all pulled from 2.5):

        - reintroduce sync wake ups
        - whitespace cleanup, trivial cleanups
        - remove frozen lock and introduce new arch-specific
          switch_mm() logic
        - new rq_lock and rq_unlock methods
        - wake_up optimization
        - nr_uninterruptible optimization for count_active_tasks
        - merge the task CPU affinity system calls
        - sched_yield bugfix
        - minor fixes

Compiles on x86 UP and SMP.

Since Ingo recently posted 2.4-ac resyncs, I will refrain.

As I am the one doing these 2.4 patches, I will invariably be asked
whether I intend for the O(1) scheduler to be merged into 2.4. The
answer is a strong NO.

Enjoy,

        Robert Love
