Here's a patch from Andrea's tree that uses IRQ_BALANCE_INTERVAL to
define how often interrupts are balanced, staying independent from HZ.

  It also makes sure that there _is_ a change to the configuration
before it actually writes it.  It reminds me of the mod_timer
optimization.

the attached patch updates a number of items:

 - adds cleanups suggested by Christoph Hellwig: needed unlikely()
   statements, a superfluous #define and line length problems.

 - splits up the global ptrace list into per-task ptrace lists. This was
   pretty straightforward, and this makes the worst-case exit() latency
   O(nr_children).

the per-task ptrace lists unearthed a bug that the previous code did not
take care of: tasks on the ptrace list have to be correctly reparented as
well. This patch passed my stresstests as well.

oh, setup.S. nasty indeed, bogus GDT limit.

This updates the CLONE_CLEARTID case to use futexes to make it easier
to wait for a thread exit.

glibc/pthreads had been updated to use the TID-futex, this removes an
extra system-call and it also simplifies the pthread_join() code.  The
pthreads testcode works just fine with the new kernel and does not work
with a kernel that does not do the futex wakeup, so it's working fine.

and the call trace instead.

This is the second part of "broken cfb* support in the 2.5.31-bk".  I
needed fbcon-cfb2 on one of my systems, and so I went through all
fbcon-* drivers and fixed them.

line_length, type, type_aux and visual were moved from display to
fb_info in last James Simmon's fbdev update.  Unfortunately lowlevel
support modules were not updated.

I want to find a way to get all those PageReserved tests out of
there, because they are very expensive.  But now is not the
time.

Make sure that the VC tty pointer is cleared when the tty is free'd.

bit of cleaning later.

a bit later

Note: I've also fixed several obvious "forgot to update" problems (changed
prototype of blk_init_queue(), etc.) but I hadn't touched the DMA-mapping
stuff, so it still doesn't work with 2.5; moreover, it misses a lot of fixes
done in 2.4, but that's fun for Alan - he's the maintainer

Well I didn't test that very well.  __page_cache_release() is doing a
__free_page() on a zero-ref page, so __free_pages() sends the refcount
negative and doesn't free it.  With patch #8, page_cache_release()
almost never frees pages, but it must have been leaking a little bit.
Lucky it showed up.

This fixes it, and also adds a missing PageReserved test in put_page().
Which makes put_page() identical to page_cache_release(), but there are
header file woes.  I'll fix that up later.

This trivial patch reorders the unlocking in rq_unlock()... I was
tired of getting stack dumps in my messages file.

isn't ready for it (either during early boot, or at shutdown)
