xen: pvhvm: make it clearer that XEN_UNPLUG_* define bits in a bitfield 2010-08-23T11:01:35+00:00 Ian Campbell ian.campbell@citrix.com 2010-08-23T11:01:35+00:00 9c35e90c6fcf7f5baf27a63d9565e9f47633f299 by defining in terms of (1<<N). XEN_UNPLUG_UNNECESSARY and XEN_UNPLUG_NEVER are only used within the kernel and are not defined as a bit on the unplug IO port.

xen: pvhvm: rename xen_emul_unplug=ignore to =unnnecessary 2010-08-23T10:59:29+00:00 Ian Campbell ian.campbell@citrix.com 2010-08-23T10:59:29+00:00 1dc7ce99b091a11cce0f34456c1ffcb928f17edd It is not immediately clear what this option causes to become ignored. The actual meaning is that it is not necessary to unplug the emulated devices to safely use the PV ones, even if the platform does not support the unplug protocol. (pressumably the user will only add this option if they have ensured that their domain configuration is safe). I think xen_emul_unplug=unnecessary better captures this.
