-From: Jan Beulich <jbeulich@suse.com>
-Subject: x86/MSI: disallow redundant enabling
-
-At the moment, Xen attempts to allow redundant enabling of MSI by
-having pci_enable_msi() return 0, and point to the existing MSI
-descriptor, when the msi already exists.
-
-Unfortunately, if subsequent errors are encountered, the cleanup
-paths assume pci_enable_msi() had done full initialization, and
-hence undo everything that was assumed to be done by that
-function without also undoing other setup that would normally
-occur only after that function was called (in map_domain_pirq()
-itself).
-
-Rather than try to make the redundant enabling case work properly, just
-forbid it entirely by having pci_enable_msi() return -EEXIST when MSI
-is already set up.
-
-This is part of XSA-237.
