[Qemu-ppc] [PATCH 0/5] spapr_cpu_core: fixes and cleanups

[Greg Kurz]

This series is a follow-up to David's "Better handling of machine specific
per-cpu information" v3 patchset. It addresses issues mentioned at:

https://lists.nongnu.org/archive/html/qemu-ppc/2018-06/msg00514.html

This series fixes potential crashes and leaks in case of error during
CPU hotplug. It hence assumes that the machine_data pointer is set a
bit earlier as suggested at the above URL, for CPU hotplug to work.

Patch 1 is just code cleanup.

Patch 2 fixes a 2.12 regression.

Patch 3 fixes a long standing issue. It could possibly be fixed in
current master but this would require to rebase David's series on
top of it. Not sure it's worth the pain.

Patch 4 and 5 are some more cleanup.
