Here's my first pull request for qemu-5.2, which has quite a few
 accumulated things.  Highlights are:
 
  * Preliminary support for POWER10 (Power ISA 3.1) instruction emulation
  * Add documentation on the (very confusing) pseries NUMA configuration
  * Fix some bugs handling edge cases with XICS, XIVE and kernel_irqchip
  * Fix icount for a number of POWER registers
  * Many cleanups to error handling in XIVE code
  * Validate size of -prom-env data
