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!

sanitize <linux/prefetch.h> usage Commit e66eed651fd1 ("list: remove prefetching from regular list iterators") removed the include of prefetch.h from list.h, which uncovered several cases that had apparently relied on that rather obscure header file dependency. So this fixes things up a bit, using grep -L linux/prefetch.h $(git grep -l '[^a-z_]prefetchw*(' -- '*.[ch]') grep -L 'prefetchw*(' $(git grep -l 'linux/prefetch.h' -- '*.[ch]') to guide us in finding files that either need <linux/prefetch.h> inclusion, or have it despite not needing it. There are more of them around (mostly network drivers), but this gets many core ones.

asm-generic: xor: mark static functions as __maybe_unused The asm-generic/xor.h header file is nasty and defines static functions that are not inline. The header file is include by the ARM version of asm/xor.h, which uses some but not all of the symbols defined there. Marking the extraneous functions as __maybe_unused lets gcc drop them without complaining. Without this patch, building iop13xx_defconfig results in: include/asm-generic/xor.h:696:34: warning: 'xor_block_8regs_p' defined but not used [-Wunused-variable] include/asm-generic/xor.h:704:34: warning: 'xor_block_32regs_p' defined but not used [-Wunused-variable] Signed-off-by: Arnd Bergmann <arnd@arndb.de> Cc: Herbert Xu <herbert@gondor.apana.org.au> Cc: Dan Williams <dan.j.williams@gmail.com> Cc: Neil Brown <neilb@suse.de>

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!
