[PATCH 00/26] KVM: PPC: Mid-August patch queue

[Alexander Graf]

Howdy,

This is my local patch queue with stuff that has accumulated over the last
weeks on KVM for PPC with some last minute fixes, speedups and debugging help
that I needed for the KVM Forum ;-).

The highlights of this set are:

  - Converted most important debug points to tracepoints
  - Flush less PTEs (speedup)
  - Go back to our own hash (less duplicates)
  - Make SRs guest settable (speedup for 32 bit guests)
  - Remove r30/r31 restrictions from PV hooks (speedup!)
  - Fix random breakages
  - Fix random guest stalls
  - 440GP host support (Thanks Hollis!)

Keep in mind that this is the first version that is stable on PPC32 hosts.
All versions prior to this could occupy otherwise used segment entries and
thus crash your machine :-).

After finally meeting Avi again, we also agreed to give pulls a try. So
here we go - this is my tree online:

Have fun with more accurate, faster and less buggy KVM on PowerPC!
