Hello, The following series aims to change the default x2APIC Destination mode from Logical to Physical. This is done in order to cope with boxes that don't have a huge amount of CPUs, but do have a non trivial amount of PCI devices using MSI(-X).
The default x2APIC destination mode can now be set from Kconfig, and will default to phys in order to reliable boot on all boxes. Further patches are a bit of cleanup related to the interrupt limits reported at boot, and making those values more realistic. Thanks, Roger.
