Subject: RE: [PATCH hyperv-next v3 05/15] Drivers: hv: Rename fields for SynIC
 message and event pages

Slight tweak -- tie this to having two SynICs:

Confidential VMBus requires interacting with two SynICs -- one
provided by the host hypervisor, and one provided by the paravisor.
Each SynIC requires its own message and event pages.

Rename the existing host-accessible SynIC message and event pages
with the "hyp_" prefix to clearly distinguish them from the paravisor
ones. The field name is also changed in mshv_root.* for consistency.

No functional change.
