2012-10-29Fix reading of number of interrupts for IO-APICsNico Huber
The number read from the io-apic register represents the index of the highest interrupt redirection entry, i.e. the number of interrupts minus one.

2012-04-23Unbreak boards where chipset can select between FSB and serial APIC busRudolf Marek
Commit d4d5e4d3e10da06a83d57a147bd58a733381de18 contains #ifdef instead of #if, making the FSB/serial bus selection for APIC always select serial bus. The bug is harmless on most chipsets because the bit is often RO, but it breaks at least on VIA K8T890.

2012-03-16Via Epia-N and C3: Set ioapic delivery type in KconfigPatrick Georgi
The original comment says it's a Via C3 and not Epia requirement to deliver IOAPIC interrupts on APIC serial bus.
