The patch is against linux-2.1.131-ac3:
ftp://e-mind.com/pub/linux/arca-tree/arca-47-against-2.1.131-ac3.diff.gz
Differences between linux-2.1.131-ac3:
o get_wchan() moved in arch specific section and CTRL+SCROLL-LOCK
use get_wchan() to get the PC filed information. Due this change
the arca-47 kernel compile only on i386 and alpha (alpha is just
uptodate too).
o fixed a little bug in a emergency SMP code in irq.c (Ingo and
Linus)
o idle task reschedule fix (SCHED_YIELD was not enough)
o fixed APM that would go in ap_do_idle() even if the CPU is been
busy for a lot of time
o jiffies wrap update (note 2.1.131 ac3 in hp100 has some jiffy
wrap bug caused by me that I fixed some weeks ago after a bug
report)
o reversed a patch (that I think it' s buggy) in ac3 in the 3c509
device driver
o aic7xxx experimental timer handler and a mod_timer cleanup
o fixed scsi code to not hang after ~0UL sec after the first
scsi reset
o ppa reset handler set (avoid kernel crash in case of reset of the
ppa host forced by the scsi midlevel driver)
o reimplemented time to jiffies functions handling all kind
of overflows, it fixes also a schedule_timeout() printk flood
due to an overflow in timeout = (timeout*HZ+999)/1000+1; in poll()
o removed unused flag from the mmstruct since we don't do aging
anymore
o reversed some changes in 2.1.130 that was causing an excessive
swapout, the changes would make sense if we would run
shrink_mmap() after every swapout.
o new delayed ack heuristic invented by me to handle better
performance on congestioned networks
o in shrink_mmap() I stop trying to free pages if I just tried
on a lot of freeable pages (and not not freeables ones)
o my own kswapd implementation that runs in background and
schedule() as a normal process but with dynamic priority
o anti swap cache garbage patch, probably it make no differences
but works fine
o give a sense to swap cache statistics
o little vmalloc fix
o kernel compile without sysctl
o some minor things
