-Subject: [PATCH] xen/MSI: don't open-code pass-through of enable bit
- modifications
-
-Without this the actual XSA-131 fix would cause the enable bit to not
-get set anymore (due to the write back getting suppressed there based
-on the OR of emu_mask, ro_mask, and res_mask).
-
-Note that the fiddling with the enable bit shouldn't really be done by
-qemu, but making this work right (via libxc and the hypervisor) will
-require more extensive changes, which can be postponed until after the
-security issue got addressed.
-
-This is a preparatory patch for XSA-131.
