[Qemu-devel] [PATCH 2/3] s390x/css: advertise unrestricted cssids

[Halil Pasic <pasic@linux.vnet.ibm.com>]

Let us advertise the changes introduced by "s390x/css: unrestrict cssids"
to the management software (so it can tell are cssids unrestricted or
restricted).

Signed-off-by: Halil Pasic <pasic@linux.vnet.ibm.com>

Boris says having the property on the virtual-css-bridge is good form
Libvirt PoV. @Shalini: could you verify that things work out fine
(provided we get at least a preliminary blessing from Connie).

Consider squashing into "s390x/css: unrestrict cssids".
