Ping!  There has been no substantive feedback to this version of
the patch in the week since I posted it, which optimistically suggests
to me that people may be satisfied with it.  If that's true, Frederic,
I assume this would be pulled into your tree?

I have slightly updated the v9 patch series since this posting:

- Incorporated a fix to initialize cpu_isolation_mask early if no
  cpu_isolation= boot argument was given, to avoid crashing on
  CPUMASK_OFFSTACK platforms.

- Incorporated Mark Rutland's changes to convert arm64
  assembly to C code instead of using my own version.

Please avoid queuing these patches -- the first is already in the arm64
queue for 4.5 and the second was found to introduce a substantial
performance regression on the syscall entry/exit path. I think Mark had
an updated version to address that, so it would be easier not to have
an old version sitting in some other queue!

Cheers,
