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!

MIPS: Refactor 'clear_page' and 'copy_page' functions. Remove usage of the '__attribute__((alias("...")))' hack that aliased to integer arrays containing micro-assembled instructions. This hack breaks when building a microMIPS kernel. It also makes the code much easier to understand. [ralf@linux-mips.org: Added back export of the clear_page and copy_page symbols so certain modules will work again. Also fixed build with CONFIG_SIBYTE_DMA_PAGEOPS enabled.] Signed-off-by: Steven J.
