Cover letter [PATCH 0/9][v6] Enable MSI for KVM

MSI patchset v6 is coming...

v5->v6

Addressed all comments from Avi on v5. I also set msi2intx=0 in non-x86 architecture machines.

And the TODO list after this patchset:

1. A independence IOCTL to deliver MSI message data/address and related info, so that kvm_set_irq() can deliver MSI message directly.

2. Merge MSI parsing process with IOAPIC. Also speed it up with bit ops.

3. Separate lock for IOAPIC, maybe also LAPIC.

Thanks!
