Linus Torvalds d144746478 Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus
Pull MIPS updates from Ralf Baechle:
 "MIPS updates:

   - All the things that didn't make 3.10.
   - Removes the Windriver PPMC platform.  Nobody will miss it.
   - Remove a workaround from kernel/irq/irqdomain.c which was there
     exclusivly for MIPS.  Patch by Grant Likely.
   - More small improvments for the SEAD 3 platform
   - Improvments on the BMIPS / SMP support for the BCM63xx series.
   - Various cleanups of dead leftovers.
   - Platform support for the Cavium Octeon-based EdgeRouter Lite.

  Two large KVM patchsets didn't make it for this pull request because
  their respective authors are vacationing"

Alexandre Bounine 2ec3ba69fa rapidio: convert switch drivers to modules
Rework RapidIO switch drivers to add an option to build them as loadable
kernel modules.

This patch removes RapidIO-specific vmlinux section and converts switch
drivers to be compatible with LDM driver registration method.  To simplify
registration of device-specific callback routines this patch introduces
rio_switch_ops data structure.  The sw_sysfs() callback is removed from
the list of device-specific operations because under the new structure its
functions can be handled by switch driver's probe() and remove() routines.

If a specific switch device driver is not loaded the RapidIO subsystem
core will use default standard-based operations to configure a switch.
Because the current implementation of RapidIO enumeration/discovery method
relies on availability of device-specific operations for error management,
switch device drivers must be loaded before the RapidIO
enumeration/discovery starts.

This patch also moves several common routines from enumeration/discovery
module into the RapidIO core code to make switch-specific operations
accessible to all components of RapidIO subsystem.

Paul Gortmaker 0a422f2b1d drivers/rapidio: idt_gen2.c is implicitly relying on getting stat.h
Upon the trial removal of the implicit presence of module.h,
lots of files showed up that were getting the sub-includes
by default without calling them out.  Fix them in advance.

Alexandre Bounine 0bf2461fdd rapidio: fix default routing initialization
Fix switch initialization to ensure that all switches have default routing
disabled.  This guarantees that no unexpected RapidIO packets arrive to
the default port set by reset and there is no default routing destination
until it is properly configured by software.

This update also unifies handling of unmapped destinations by tsi57x, IDT
Gen1 and IDT Gen2 switches.

Alexandre Bounine a93192a5d2 rapidio: use common destid storage for endpoints and switches
Change code to use one storage location common for switches and endpoints.
This eliminates unnecessary device type checks during basic access
operations.  Logic that assigns destid to RIO devices stays unchanged - as
before, switches use an associated destid because they do not have their
own.
