Hello,
This series has originated from the failure discovered by osstest in:
https://lore.kernel.org/xen-devel/E1l1vyr-00074y-8j@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx/
The commit pointed by osstest is correct, but it triggers an underlying
shortcoming of the vPCI MSI handling which is fixed in patch 3.
Patches 1 and 2 are small bugfixes found in the process of diagnosing
the issue.
Thanks, Roger.
Roger Pau Monne (3):
x86/irq: remove duplicated clear_domain_irq_pirq calls
x86/irq: don't disable domain MSI IRQ on force unbind
x86/vmsi: tolerate unsupported MSI address/data fields
