ppc patch queue 2021-08-27 First ppc pull request for qemu-6.2. As usual, there's a fair bit here, since it's been queued during the 6.1 freeze. Highlights are: * Some fixes for 128 bit arithmetic and some vector opcodes that use them * Significant improvements to the powernv to support POWER10 cpus (more to come though) * Several cleanups to the ppc softmmu code * A few other assorted fixes
