Hi Kosaki,

Sorry this is slightly off topic, I am newbie and want to test out your 
patch series. I am using alpine as email client to save your patches to
/usr/src/linux-2.6/patches:

#ls -l /usr/src/linux-2.6/patches/

-rw------- 1 root src  6682 2009-07-09 10:24 km1.patch
-rw------- 1 root src  6980 2009-07-09 10:24 km2.patch
-rw------- 1 root src  9871 2009-07-09 10:24 km3.patch
-rw------- 1 root src 12539 2009-07-09 10:24 km4.patch
-rw------- 1 root src 11499 2009-07-09 10:24 km5.patch

Then I apply your patches using git-am, I got:

---------------
/usr/src/linux-2.6# git checkout experimental
Switched to branch "experimental"

/usr/src/linux-2.6# git am ./patches/km1.patch

Is there any better way that you could recommend to me to apply your 
patches cleanly? Thanks.
