[PATCH] PCI: Introduce two new MSI infrastructure calls for masking/unmasking.
Certain platforms do not allow writes in the MSI-X bars
to setup or tear down vector values. To combat against
the generic code trying to write to that and either silently
being ignored or crashing due to the pagetables being marked r/o
this patch introduces a platform over-write.
Note that we keep two separate, non-weak, functions
default_mask_msi_irqs() and default_mask_msix_irqs() for the
behavior of the arch_mask_msi_irqs() and arch_mask_msix_irqs(),
as the default behavior is needed by x86 PCI code.
For Xen, which does not allow the guest to write to MSI-X
tables - as the hypervisor is solely responsible for setting
the vector values - we implement two nops.

I put the log info in https://bugzilla.kernel.org/show_bug.cgi?id=64581 and put this in my pci/misc branch for v3.13. I added the following to the changelog: This fixes a Xen guest crash when passing a PCI device with MSI-X to the guest. See the bugzilla for more details. [bhelgaas: add bugzilla info] Reference: https://bugzilla.kernel.org/show_bug.cgi?id=64581 Let me know if this needs any tweaking. Bjorn
