  SVN rev 191455 on 2009-04-24 08:57:54Z by raj
  
  Zero PCB during early AIM PowerPC init.
  
  When memory is not zero'ed by firmware, uninitialized PCB can have bogus
  contents, which appear as a saved onfault condition, Altivec context to
  restore etc. and lead to corruption/crashes. This commit fixes such issues.
