The new-and-improved kernel-locking kerneldoc seems to be missing some end
tags which causes 'make foodocs' to die.  I'm not sure if it's because of
my not-bleeding-edge docbook utils or if it's a genuine error.  Since most
ending tags are present I tend to think it's an error.

Some places use cpu_online() where they should be using cpu_possible, most
commonly for tallying statistics.  This makes no difference without hotplug
CPU.

Use the for_each_cpu() macro in those places, providing good examples (and
making the external hotplug CPU patch smaller).

Anton: breaks PPC64, as it needs cpu_possible_mask, but fix is already
in Ameslab tree.

The for_each_cpu() and for_each_online_cpu() iterators take a mask, and
noone uses them that way (except for arch/i386/mach-voyager, which uses
for_each_cpu(cpu_online_mask).  Make them more usable iterators, by
dropping the "mask" arg.

This requires that archs provide a cpu_possible_mask: most do, but PPC64
doesn't, so it is broken by this patch.  The other archs use a #define to
define it in asm/smp.h.

Most places doing loops over cpus testing for cpu_online() should use
for_each_cpu: it is synonymous at the moment, but with the CPU hotplug
patch the difference becomes important.

Followup patches will convert users.

A non-critical corner case has come up for interactivity that I believe needs 
to be addressed. It is only extensive testing and examination that revealed
this, as this interactivity work is in maintenance mode.

Description:

  It is possible for a highly interactive task (like X) to cause large
  latencies in tasks that are less 'niced' (eg negative nice number
  compared to X which should normally run at nice 0) if they are fully
  cpu bound.  This occurs due to expiration of the cpu bound tasks.

  This patch addresses this by not reinserting interactive tasks into
  the active array if there is a better static priority task running but
  has been placed on the expired array.  This causes a substantial
  reduction in the maximum scheduling latency a task with a less nice
  value can have. 

  This also has the positive side effect of maintaining better cpu%
  proportions for tasks of different nice levels.

Testers will only be able to discern a difference with highly cpu bound tasks 
of normal scheduling policy at different nice levels. Test cases are doing 
something cpu intensive relatively -niced in the presence of an interactive
load (eg capturing and encoding video at nice -10 while using X nice 0, or 
something nice 0 vs nice +10) and so on. Because of the crossover of 10 
'nice' levels of dynamic priorities between interactive and cpu bound tasks
this patch will have a more noticable effect as the nice difference is
greater, especially 11 or more.

fasync_helper and kill_fasync are helpers for managing F_SETFL fcntl 
calls that change FASYNC and sending the necessary signals. The locking 
uses one global rwlock that's acquired for read in all kill_fasync
calls, and that causes cache line trashing. This is not necessary: if
the fasync list is empty, then there is no need to acquire the rwlock.
Tests with reaim on a 4-way pIII on STP showed an 80% reduction of the
time within kill_fasync.

CONFIG_EPOLL=n space reduction in struct file.

From: Bram Stolk <bram@sara.nl>

All modes that exceed the native resolution of a flatpanel are discarded.
However, a CRT has native resolution set to 0, and therefore, tridentfb.c
cannot be used with a CRT.
