POWER8 and POWER9 have 12-bit LPIDs. Change LPID_RSVD to support up to (4096 - 2) guests on these processors. POWER7 is kept the same with a limitation of (1024 - 2), but it might be time to drop KVM support for POWER7. Tested with 2048 guests * 4 vCPUs on a witherspoon system with 512G RAM and a bit of swap. Signed-off-by: Cédric Le Goater <clg@kaod.org>
Thanks, patch applied to my kvm-ppc-next branch. Paul.
