2007-05-02[PATCH] x86: default to physical mode on hotplug CPU kernelsIngo Molnar
Default to physical mode on hotplug CPU kernels. Furher simplify and clean up the APIC initialization code.

2006-12-07[PATCH] x86: fix the irqbalance quirk for E7320/E7520/E7525Siddha, Suresh B
Move the irqbalance quirks for E7320/E7520/E7525(Errata 23 in http://download.intel.com/design/chipsets/specupdt/30304203.pdf) to early quirks. And add a PCI quirk for these platforms to check(which happens very late during the boot) if the APIC routing is indeed set to default flat mode. This fixes the breakage(in x86_64) of this quirk due to cpu hotplug which selects physical mode instead of the logical flat(as needed for this errata workaround).

2006-09-26[PATCH] i386: Allow to use GENERICARCH for UP kernelsAndi Kleen
There are some machines around (large xSeries or Unisys ES7000) that need physical IO-APIC destination mode to access all of their IO devices. This currently doesn't work in UP kernels as used in distribution installers. This patch allows to compile even UP kernels as GENERICARCH which allows to use physical or clustered APIC mode.

2005-06-23[PATCH] Do not enforce unique IO_APIC_ID check for xAPIC systems (i386)Natalie Protasevich
This patch is per Andi's request to remove NO_IOAPIC_CHECK from genapic and use heuristics to prevent unique I/O APIC ID check for systems that don't need it. The patch disables unique I/O APIC ID check for Xeon-based and other platforms that don't use serial APIC bus for interrupt delivery. Andi stated that AMD systems don't need unique IO_APIC_IDs either.

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!
