  Subject: [PATCH] powerpc/eeh: Remove EEH_PE_PRI_BUS in full hotplug recovery

  commit 59ae8c6d5b45 ("powerpc/eeh: Fix invalid cached PE primary
  bus") was wrongly backporting upstream commit a3aa256b7258: It
  should clear the PE's flag (EEH_PE_PRI_BUS) in full hotplug instead
  of partial hotplug scenario.

  This fixes the issue by clearing EEH_PE_PRI_BUS in full hotplug
  scenario only.

  Seems like this is easily recreatable. Mike Vageline just hit the
  issue by doing couple of PERST on a FlashGT card.

  Here is the note from him -
  I had downloaded 0908, then perst, modprob'd to verify 0908, then rmmod, then 
perst to factory, modprob'd, verified it was 0903, rmmod, then perst again to 
user... xmon
