Subject: [PATCH 0/33] Make static

Hi,

The following patches make things static, found by sparse. They are only used in
the file where they are declared.

I first compiled the kernel using sparse. and piped output to
../logs/make_yes_log_20081203155529

Then I used the script below, but made some manual changes as well. I tested
changes with checkpatch, have built it successfully with allnoconfig,
allmodconfig and allyesconfig.

Thanks,

Roel
