      powerpc: Factoring mpic cpu id fetching into a function · d6a2639b
      由 Meador Inge 提交于 
      The following code snippet:

	unsigned int cpu = 0;
	if (mpic->flags & MPIC_PRIMARY)
		cpu = hard_smp_processor_id();

is seen in several places in the 'mpic.c' code.  This changeset factors
that pattern out into a helper function called 'mpic_processor_id'.

      powerpc: Make MPIC honor the "pic-no-reset" device tree property · dfec2202
      由 Meador Inge 提交于 
      This property, defined in the Open PIC binding, tells the kernel not to use
the reset bit in the global configuration register.  Additionally, its
presence mandates that only sources which are actually used (i.e. appear in
the device tree) should have their VECPRI bits initialized.

Although, "pic-no-reset" can be used for the same use cases that
"protected-sources" is covering, the "protected-sources" implementation was
left completely intact.  This is a more pragmatic approach as there are
already several existing systems which use protected sources.  If
"pic-no-reset" *and* "protected-sources" are both used, however, then
"pic-no-reset" takes precedence in terms of the init behavior and the
sanity checks done by protected sources will still take place.

      rapidio: fix hang on RapidIO doorbell queue full condition · 12a4dc43
      由 Thomas Taranowski 提交于 
      In fsl_rio_dbell_handler() the code currently simply acknowledges the QFI
queue full interrupt, but does nothing to resolve the queue full
condition.  Instead, it jumps to the end of the isr.  When a queue full
condition occurs, the isr is then re-entered immediately and continually,
forever.

The fix is to just fall through and read out current doorbell entries.
