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

Browse Source 
Pull MIPS fixes from Ralf Baechle:
 "A fair number of fixes across the field.  Nothing terribly
  complicated; the one liners in below changelog should be fairly
  descriptive.

  Noteworthy is the SB1 change which the result of changes to binutils
  resulting in one big gas warning for most files being assembled as
  well as the asid_cache and branch emulation fixes which fix corruption
  or possible uninteded behaviour of kernel or application code.  The
  remainder of fixes are more platforms or subsystem specific"

* 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus:
  MIPS: R46000: Fix Micro-assembler field overflow for R4600 V2
  MIPS: ptrace: Avoid smp_processor_id() in preemptible code
  MIPS: Lemote 2F: cs5536: mfgpt: use raw locks
  MIPS: SB1: Fix excessive kernel warnings.
  MIPS: RC32434: fix broken PCI resource initialization
  MIPS: malta: memory.c: Initialize the 'memsize' variable
  MIPS: Fix typo when reporting cache and ftlb errors for ImgTec cores
  MIPS: Fix inconsistancy of __NR_Linux_syscalls value
  MIPS: Fix branch emulation of branch likely instructions.
  MIPS: Fix a typo error in AUDIT_ARCH definition
  MIPS: Change type of asid_cache to unsigned long
