Maybe worth to pick the following patch when it gets merged:

http://patchwork.ozlabs.org/patch/869873/

It fixes a 2.11 regression with RAM postcopy.

Patch 54 "target/ppc/spapr: Add H-Call  H_GET_CPU_CHARACTERISTICS" has a
trivial but potentially embarrassing bug (QEMU aborts if the host supports
KVM_PPC_CPU_CHAR_BCCTRL_SERIALISED and cap-ibs="fixed" is used).

A patch was sent to the list:

http://patchwork.ozlabs.org/patch/868426/

AFAIK David Gibson (Cc'd) is away and I don't know when this patch
will be merged.

Cheers,
