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 _ASM_IRQ_VECTORS_LIMITS_H`

paravirt: increase IRQ limit When running with CONFIG_PARAVIRT, we may want lots of IRQs even if there's no IO APIC. Signed-off-by: Jeremy Fitzhardinge <jeremy@xensource.com> Cc: "Eric W.
