 - if you happen to come by patches that you think may be of use, test them on your own ~ and then, if interested, you can pass them along to L_Pa, if that floats your boat ;)

 - I've included a Patch from Zen-kernel (which is applied) to allow users who may want additional C/CXXFLAG optimizations for their kernel. I don't recommend you use this, unless you know how. Particularly, do not mess with LDFLAGS. It may be useful at a later date for things Like -flto (lik-time optimizations in GCC), but not until some support (elsewhere) is added for that.  The C/CXXFLAGS can be useful though.

 - Some patches are non-applied by default, such as reverting stable page writes in EXT4 (which i have been reverting throughout the 3.0+ rt-kernel development, in order to avoid some performance penalties on my systems). I don't recommended using the patch, unless you understand the risks; it is a performance hack and sacrifices a little bit of data-integrity for a nice perfomance gain. therefore, it _could_ be dangerous for some use cases.
