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 18:20:36 -04:00			`#ifndef __ASM_MACH_APICDEF_H`

[PATCH] x86: convert bigsmp to use flat physical mode When we bring up a new CPU via INIT/startup IPI messages, the CPU that's coming up sends a xTPR message to the chipset. Intel chipsets (at least) don't provide any architectural guarantee on what the chipset will do with this message. For example, the E850x chipsets uses this xTPR message to interpret the interrupt operating mode of the platform. When the CPU coming online sends this message, it always indicates that it is in logical flat mode. For the CPU hotplug case, the platform may already be functioning in cluster APIC mode at this time, the chipset can get confused and mishandle I/O device and IPI interrupt routing. The situation eventually gets corrected when the new CPU sends another xTPR update when we switch it to cluster mode, but there's a window during which the chipset may be in an inconsistent state. This patch avoids this problem by using the flat physical interrupt delivery mode instead of cluster mode for bigsmp (>8 cpu) support.
