I mean the linux kernel.  The spe_gang_context was defined in the libspe2
interface, but I'm pretty sure that it doesn't change any behavior.
IIRC, this was dicussed on the cbe-oss-dev mailing list, which was the
place for discussion of everything about Cell on Linux.

FWIW, you should be able to set the flag in opts like this:

  opts = gcell.jm_options(ph, 1)
  opts.gang_schedule = True
