[PATCH] ppc64: Remove lpqueue pointer from the paca on iSeries
The iSeries code keeps a pointer to the ItLpQueue in its paca struct. But
all these pointers end up pointing to the one place, ie. xItLpQueue.
So remove the pointer from the paca struct and just refer to xItLpQueue
directly where needed.
The only complication is that the spread_lpevents logic was implemented by
having a NULL lpqueue pointer in the paca on CPUs that weren't supposed to
process events. Instead we just compare the spread_lpevents value to the
processor id to get the same behaviour.
