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! 2005-04-16 22:20:36 +00:00			`#ifndef __ALPHA_PERCPU_H`

[PATCH] Alpha: increase PERCPU_ENOUGH_ROOM Module loading on Alpha was failing with error "Could not allocate 8 bytes percpu data". Looking at dmesg we have the below error "No per-cpu room for modules." Increase the PERCPU_ENOUGH_ROOM in a similar way as x86_64 Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@gmail.com> Cc: <Jay.Estabrook@hp.com> Cc: Richard Henderson <rth@twiddle.net> Cc: Ivan Kokshaysky <ink@jurassic.park.msu.ru> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> 2007-02-10 09:43:22 +00:00			`/*`
