[PATCHSET] Linux 2.4.18-rc4-jam2

[J.A. Magallon]

Hi, lkml readers.

After one other session of patch messing, here is rc4-jam2. Main update
is vm-25 -> vm-27 from Andrea. Get it as usual at:

http://giga.cps.unizar.es/~magallon/linux/kernel/2.4.18-rc4-jam2/

and as not so usual at:

http://giga.cps.unizar.es/~magallon/linux/kernel/2.4.18-rc4-jam2.tar.gz

I have reordered the patches to make easier to test cleanly subsystems:
- 0* is VM update. It applies cleanly (and after a compiler.h addendum,
  builds cleanly) on 18-rc4, for people that only want to test AA-vm
  vs RMAP-vm (hint, hint...)
- 1* are tiny smp enhancements, that I think are safe.
- 2* are O1 scheduler and low-latency
- 3* are SCSI-IDE updates.
- 5* mixed things...
- 6* sensors
- 7* bproc
- 8* miscelanea

Fore serious tests, I would not apply anything >=50, unless you are
interested on something there.

Good luck. My box lives (see signature).

Some recent jam patchsets next to -aa at:
http://home.earthlink.net/~rwhron/kernel/jam.html

There is a lot of common code in the kernels tested, but there are
a few notables:
-aa about 30% faster on the Open Source Database Benchmark
-aa 10-20% faster on tests involving lots of forks.
-jams about 15% faster on tbench
Lots of variation in tiobench.

The tiobench numbers are the most intriguing.  
Hoping someone can make sense of them.

What's this?

Beowulf Process Space (http://bproc.sourceforge.net/).
A kernel set of patches and modules to make a cluster look like
a single box wrt process management (SSI, single system image),
and allow efficient process migration between boxes. This is
just the part that patches the kernel.

Note this location is not an official one for BProc, but just my
hack to have the patch applying on recent development kernels,
and can be broken in some hidden way.
