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!

[PATCH] frv: implement and export various things required by modules Export a number of features required to build all the modules. It also implements the following simple features: (*) csum_partial_copy_from_user() for MMU as well as no-MMU. (*) __ucmpdi2(). so that they can be exported too.
