[ltp] PnP Bios patch help

[Tod Harter]

What I hate is the fact that most patches assume you are applying them from 
OUTSIDE the source tree for the project. This -p0 vs -p1 thing is THE place 
where every neophyte gets tripped up, 100% chance. I have always thought 
Larry Wall should have made the '-p1' behaviour be the default, thus 
encouraging people to locate their patches INSIDE the source tree they were 
patching...

Well, that should be really easy, as Marty says. The default settings for 
most things build you a pretty sane kernel, though there are often some 
useful features they don't compile in. What I always do is I keep a copy of 
my old config.h file, then diff it with the one for the new kernel version 
I'm making. tkdiff is execellent for this by the way. That gives you a pretty 
instant view of what the variations are between your old running kernel 
config and the new one, and you can usually just merge the 2 with tkdiff. 
Beware though of distribution supplied kernel sources, they rarely match the 
actual running kernels :(.
