Hi there,
I've played around with Andrew Morton's script to remove trailing white spaces in kernel patches.
http://www.zip.com.au/~akpm/linux/patches/stuff/tpp.txt
I used it against the official patches from http://www.kernel.org and this is the result:
Kernelversion Size of the patch Size without trailing WS Number of trailing WS percent of patch
2.6.12 24539730 24531535 8195 0.0334%
