[PATCH 0/3] target/ppc: fix tlb flushing race

[Nicholas Piggin]

ppc broadcast tlb flushes should be synchronised with other vCPUs,
like all other architectures that support such operations seem to
be doing.

Fixing ppc removes the last caller of the non-synced TLB flush
variants, we can remove some dead code. I'd like to merge patch 1
for 9.0, and hold patches 2 and 3 until 9.1 to avoid churn (unless
someone prefers to remove the dead code asap).

Thanks,
Nick
