    powerpc: Copy only required pieces of the mm_context_t to the paca
    
    Currently we copy the whole mm_context_t to the paca but only access a
    few bits of it.  This is wasteful of space paca and also takes quite
    some time in the hot path of context switching.
    
    This patch pulls in only the required bits from the mm_context_t to
    the paca and on context switch, copies only those.
    
    Benchmarking this (On top of Anton's recent MSR context switching
    changes [1]) using processes and yield shows an improvement of almost
    3% on POWER8:
    
      http://ozlabs.org/~anton/junkcode/context_switch2.c
      ./context_switch2 --test=yield --process 0 0
