      Alright, this one is only triggered when slab debugging is enabled.  The
      slabs are assumed to be aligned on a HUGEPTE_TABLE_SIZE boundary.  The free
      path makes use of this assumption and uses the lowest nibble to pass around
      an index into an array of kmem_cache pointers.  With slab debugging turned
      on, the slab is still aligned, but the "working" object pointer is not.
      This would break the assumption above that a full nibble is available for
      the PGF_CACHENUM_MASK.
      
      The following patch reduces PGF_CACHENUM_MASK to cover only the two least
      significant bits, which is enough to cover the current number of 4 pgtable
      cache types.  Then use this constant to mask out the appropriate part of
      the huge pte pointer.

      [POWERPC] Fix might-sleep warning on removing cpus · 81b73dd9
      Haren Myneni authored
      Noticing the following might_sleep warning (dump_stack()) during kdump
      testing when CONFIG_DEBUG_SPINLOCK_SLEEP is enabled. All secondary CPUs
      will be calling rtas_set_indicator with interrupts disabled to remove
      them from global interrupt queue.

      To fix this issue, rtas_set_indicator_fast() is added so that will not
      wait for RTAS 'busy' delay and this new function is used for kdump (in
      xics_teardown_cpu()) and for CPU hotplug ( xics_migrate_irqs_away() and
      xics_setup_cpu()).
      
      Note that the platform architecture spec says that set-indicator
      on the indicator we're using here is not permitted to return the
      busy or extended busy status codes.

      [POWERPC] fix PMU initialization on pseries lpar · dcc42f48
      Sonny Rao authored
      We should not be calling power4_enable_pmcs() in
      pseries_lpar_enable_pmcs(); just doing the hypercall is sufficient.
      Prior to 2.6.15 we did not call power4_enable_pmcs() for an lpar.
      
      power4_enable_pmcs() tries to read the hid0 register which is no
      longer legal for an lpar in newer Power processors.
