XIVE2 has the concepts of a Group of interrupts and a Crowd of interrupts
(where a crowd is a group of Groups). These patch sets are associated with:
 - NVGC tables
 - Group/Crowd level notification
 - Incrementing backlog countets
 - Backlog processing
 - NVPG and NVC Bar MMIO operations
 - Group/Crowd testing
 - ESB Escalation
 - Pool interrupt testing

version 2:
 - Removed printfs from test models and replaced with g_test_message()
 - Updated XIVE copyrights to use: 
   SPDX-License-Identifier: GPL-2.0-or-later
 - Set entire NSR to 0, not just fields
 - Moved rename of xive_ipb_to_pipr() into its own patch set 0002
 - Rename xive2_presenter_backlog_check() to 
   xive2_presenter_backlog_scan()
 - Squash patch set 11 (crowd size restrictions) into 
   patch set 9 (support crowd-matching)
 - Made xive2_notify() a static rou
