Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

char/mwave: make some arrays static const to make object code smaller Don't populate arrays on the stack but make them static. Makes the object code smaller. Also remove temporary variables that have hard coded array sizes and just use ARRAY_SIZE instead and wrap some lines that are wider than 80 chars to clean up some checkpatch warnings.
