[ANNOUNCE] 3.1.0-ck1

[ANNOUNCE] 3.1.0-ck1

[Con Kolivas]

These are patches designed to improve system responsiveness and interactivity 
with specific emphasis on the desktop, but suitable to any commodity hardware 
workload.

As it may take some time to get a kernel.org account, I have started hosting 
these patches exclusively on my site for now. 


Apply to 3.1.x:
http://ck.kolivas.org/patches/3.0/3.1/3.1.0-ck1/patch-3.1.0-ck1.bz2


Broken out tarball:
http://ck.kolivas.org/patches/3.0/3.1/3.1.0-ck1/3.1.0-ck1-broken-out.tar.bz2


Discrete patches:
http://ck.kolivas.org/patches/3.0/3.1/3.1.0-ck1/patches/


BFS by itself:
http://ck.kolivas.org/patches/bfs/


Web:
http://kernel.kolivas.org


Code blog when I feel like it:
http://ck-hack.blogspot.com/


Each discrete patch usually contains a brief description of what it does at 
the top of the patch itself.

Full patchlist:

3.1-sched-bfs-414.patch
sched-add-above-background-load-function.patch
mm-minimal_swappiness.patch
mm-enable_swaptoken_only_when_swap_full.patch
mm-drop_swap_cache_aggressively.patch
mm-kswapd_inherit_prio-1.patch
mm-background_scan.patch
mm-idleprio_prio-1.patch
mm-lru_cache_add_lru_tail-1.patch
mm-decrease_default_dirty_ratio.patch
kconfig-expose_vmsplit_option.patch
hz-default_1000.patch
hz-no_default_250.patch
hz-raise_max.patch
preempt-desktop-tune.patch
cpufreq-bfs_tweaks.patch
ck1-version.patch


This is mainly a resync with the linux-3.1 kernel apart from the minor 
improvements and cleanups that were committed to the BFS CPU scheduler.

Tried here with Mini2440 (=ARM arch) to compile:

[...]
In file included from kernel/sched.c:2:0:
kernel/sched_bfs.c: In function 'schedule':
kernel/sched_bfs.c:3224:4: error: implicit declaration of function 'prefetch'

This ^ one I tried to apply, but it fails with:
[...]
patching file include/linux/sched.h
Hunk #1 FAILED at 1600.
Hunk #2 FAILED at 1647.
2 out of 2 hunks FAILED -- rejects in file include/linux/sched.h

Perhaps you used the wrong -p or --strip option?

With that fix it compiles fine. Problem is that prefetch is defined in
ARM headers only for version > v5 (mini is v4).

Thanks for that. The prefetch is only of questionable advantage so it can be 
removed entirely. The following patch should fix it:
