This is the updated patchset that fixes issues reported during the last
merge to upstream-sfr.

The first patch is a new change that moves the TLB handlers from arrays
in .data to functions defined in tlb-funcs.S to fix the microMIPS issue

The second patch has the changes to use scratch registers when
MIPS_PGD_C0_CONTEXT is not defined - this has not changed.

The third has a fix for the compile error  on IP27 platform.

Jonas already has posted for
the other issue (crash on bcm63xx and mti platforms)


Jayachandran C (3):
  MIPS: Move generated code to .text for microMIPS
  MIPS: mm: Use scratch for PGD when !CONFIG_MIPS_PGD_C0_CONTEXT
  MIPS: Move definition of SMP processor id register to header file
