[PATCH 00/26] target/ppc: TCG improvements and fixes

[Nicholas Piggin]

This is mostly TCG core emulation improvements and fixes. I
got the chiptod model in there because it's intertwined with
TFMR SPR.

Other non-TCG patches are spapr MSR entry point change which
goes together with the other machine check / MSR[ME] fixes.
And Saif's gdb patches, as well as some SPR renaming.

Will probably a bit more similar patches too, e.g., Dan's SPR
patches, but I'll just get this out for review before
upstreaming it.

Thanks,
Nick
