Stefan Hajnoczi 179938097d ppc patch queue for 2022-10-29:
This queue has the second part of the ppc4xx_sdram cleanups, doorbell
 instructions for POWER8,  new pflash handling for the e500 machine and a
 Radix MMU regression fix.
 
 It also has a lot of performance optimizations in the PowerPC emulation
 done by the researchers of the Eldorado institute. Between using gvec
 for VMX/VSX instructions, a full rework of the interrupt model and PMU
 optimizations, they managed to drastically speed up the emulation of
 powernv8/9/10 machines.  Here's an example with avocado tests:
 
 - with master:
 
 tests/avocado/boot_linux_console.py:BootLinuxConsole.test_ppc_powernv8:
 PASS (38.89 s)
 tests/avocado/boot_linux_console.py:BootLinuxConsole.test_ppc_powernv9:
 PASS (43.89 s)
 
 - with this queue applied:
 
 tests/avocado/boot_linux_console.py:BootLinuxConsole.test_ppc_powernv8:
 PASS (21.23 s)
 tests/avocado/boot_linux_console.py:BootLinuxConsole.test_ppc_powernv9:
 PASS (22.58 s)
 
 Other ppc machines, like pseries, also had a noticeable performance
 boost.
