Bug description:
  ---Problem Description---
  Recursive PHB error from EEH recovery on Shiner adapter
    
  ---uname output---
  Ubuntu 14.04.3 LTS (3.19.0-30)
   
  Machine Type = Firestone 
    
  ---Steps to Reproduce---
   When injecting EEH error (frozen PE) to BCM57800 on ubuntu 14.04.3, the EEH error is recovered automatically. However I saw recursive fenced PHB error during the recovery, which isn't the expected behaviour. After checking the ubuntu's kernel source repository, I found one patch, which as merged to powerpc/next branch recently, is missed as below. This bug is opened to tracking the backporting. Please help to mirror to Canonical accordingly, thanks!
