  selftests/powerpc: Fix compilation issue due to asm label (2018-11-01 10:06:03 +1100)

- ------------------------------------------------------------------
powerpc fixes for 4.20 #2

Some things that I missed due to travel, or that came in late.

Two fixes also going to stable:

 - A revert of a buggy change to the 8xx TLB miss handlers.

 - Our flushing of SPE (Signal Processing Engine) registers on fork was broken.

Other changes:

 - A change to the KVM decrementer emulation to use proper APIs.

 - Some cleanups to the way we do code patching in the 8xx code.

 - Expose the maximum possible memory for the system in /proc/powerpc/lparcfg.

 - Merge some updates from Scott: "a couple device tree updates, and a fix for a
   missing prototype warning."

A few other minor fixes and a handful of fixes for our selftests.

Thanks to:
  Aravinda Prasad, Breno Leitao, Camelia Groza, Christophe Leroy, Felipe Rechia,
  Joel Stanley, Naveen N. Rao, Paul Mackerras, Scott Wood, Tyrel Datwyler.
