The patch mostly fixes the ACPI irq breakage in the main tree (some bits haven't made it yet, apparently) and some per-CPU related fixes (those are just temporary workarounds; Rusty is working on the proper fix). There is one mildly interesting change: I moved per-CPU data area from region 5 to the end of region 7. This allows us to address this area via a simple "addl" (instead of movl or a GOT access). At the moment, this hardly makes a difference because the compiler can't take advantage of it. I have a prototype of a GCC patch which would change that though. Once GCC can take advantage of this feature, addressing CPU-local variables will become even cheaper. This patch hasn't received a huge amount of testing, but it does seem to work quite well for me on a 4-way Itanium 2 machine (rx5670) and the Ski simulator. Enjoy, --david
