Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus

Pull MIPS updates from Ralf Baechle:
 - Minor updates and fixes to the Octeon ethernet driver in staging
 - A fix to VGA_MAP_MEM() for 64 bit platforms
 - Fix a workaround for 74K/1074K processors
 - The symlink arch/mips/boot/dts/include/dt-bindings was pointing to a
   a file with a name ending in \n.  I think this may have been caused
   by a git bug with with patches sent by email
 - A build fix for VGA console on BCM1480-based systems
 - Fix PCI device access via "/sys/bus/pci/.../resource0" or similar
   work for Alchemy platforms
 - Fix potential data leak on MIPS R5 cores.  This doesn't add proper
   support for any R5 features, just ensures a kernel without such
   support will be secure to run
 - Adding a macros for the CP0 Config5 register to be used by the R5 fix
 - Make get_cycles() actually return something useful where possible
   This also requires a preparatory patch for performance sake
 - Fix a warning about the use of smp_processor_id() in preemptible
   code.  Again this includes a preparatory patch adding the
   infrastructure to be used by the actual patch
 - Finally remove pointless one-line comment

  MIPS: Fix invalid symbolic link file
  MIPS: PCI: pci-bcm1480: Include missing vt.h header
  MIPS: Disable usermode switching of the FR bit for MIPS R5 CPUs.
  MIPS: Add MIPS R5 config5 register.
  MIPS: PCI: Use pci_resource_to_user to map pci memory space properly
  MIPS: 74K/1074K: Correct erratum workaround.
  MIPS: Cleanup CP0 PRId and CP1 FPIR register access masks
  MIPS: Remove useless comment about kprobe from arch/mips/Makefile
  MIPS: Fix VGA_MAP_MEM macro.
