[Qemu-devel] [PULL 1/6] spapr: init CPUState->cpu_index with index relative to core-id

From: Igor Mammedov It will enshure that cpu_index for a given cpu stays the same regardless of the order cpus has been created/deleted and so it would be possible to migrate QEMU instance with out of order created CPU. Signed-off-by: Igor Mammedov Signed-off-by: David Gibson --- hw/ppc/spapr

[Qemu-devel] [PULL 2/6] Revert "spapr: Ensure CPU cores are added contiguously and removed in LIFO order"

This reverts commit 5cbc64de25973e9129c5a7897734a06ac64b9aff. Now that we have stable cpu_index values for pseries-2.7 (and future) machine types, we can now safely allow hotplug and unplug in any order. Conflicts: hw/ppc/spapr_cpu_core.c Some conflicts on revert due to some small change

[Qemu-devel] [PULL 4/6] ppc: Fix fault PC reporting for lve*/stve* VMX instructions

From: Benjamin Herrenschmidt We forgot to do gen_update_nip() for these like we do with other helpers. Fix this, but in a more efficient way by passing the RA to the accessors instead so the overhead is only taken on faults. Signed-off-by: Benjamin Herrenschmidt Signed-off-by: David Gibson ---
