Fix the conditions for enabling x2apic on guests without interrupt remapping, and support 15-bit Extended Destination ID to allow 32768 CPUs without IR on hypervisors that support it. Make the I/OAPIC code generate its RTE directly from the MSI message created by the parent irqchip, and fix up a bunch of magic mask/shift macros to use bitfields for MSI messages and I/OAPIC RTEs while we're at it. v3: • Lots of bitfield cleanups from Thomas. • Disable hyperv-iommu if 15-bit extension is present. • Fix inconsistent CONFIG_PCI_MSI/CONFIG_GENERIC_MSI_IRQ in hpet.c • Split KVM_FEATURE_MSI_EXT_DEST_ID patch, half of which is going upstream through KVM tree (and the other half needs to wait, or have an #ifdef) so is left at the top of the tree. v2: • Minor cleanups. • Move __irq_msi_compose_msg() to apic.c, make virt_ext_dest_id static. • Generate I/OAPIC RTE directly from parent irqchip's MSI messages. • Clean up HPET MSI support into hpet.c now that we can.
