[patch 0/8] PCI/MSI, x86: Cure a couple of inconsistencies

[Thomas Gleixner]

A recent discussion about the PCI/MSI management for virtio unearthed a
violation of the MSI-X specification vs. writing the MSI-X message: under
certain circumstances the entry is written without being masked.

While looking at that and the related violation of the x86 non-remapped
interrupt affinity mechanism a few other issues were discovered by
inspection.

The following series addresses these.

Note this does not fix the virtio issue, but while staring at the above
problems I came up with a plan to address this. I'm still trying to
convince myself that I can get away without sprinkling locking all over the
place, so don't hold your breath that this will materialize tomorrow.

The series is also available from git:

Thanks,
