[Qemu-devel] [PATCH v2 0/4] spapr/xics: fix migration of older machine types

[Greg Kurz]

v2: - some patches from v1 are already merged in ppc-for-2.10
    - added a new fix to a potential memory leak (patch 1)
    - consolidate dt_id computation (patch 3)
    - see individual changelogs for patch 2 and 4

This series is based on:

https://github.com/dgibson/qemu.git ppc-for-2.10

I could successfully migrate from QEMU 2.9 and back, including when the guest
has different threads per core than the host and hotplugging cores between
each migration attempt.
