This set of patches is to support building a pure microMIPS kernel
image using only instruction from the microMIPS ISA. The result is
a kernel binary reduction of more than 20% and an increase in the
speed of execution due to the smaller and faster instructions.

Steven J. Hill (9):
  MIPS: Add microMIPS configuration option.
  MIPS: Optimise core library functions for microMIPS.
  MIPS: Add support for the M14KE core.
  MIPS: Add microMIPS versions of breakpoints, BUG, etc.
  MIPS: Add support for microMIPS instructions.
  MIPS: Add support for microMIPS exception handling.
  MIPS: Support microMIPS/MIPS16e handling of delay slots.
  MIPS: Support microMIPS/MIPS16e unaligned accesses.
  MIPS: Support microMIPS/MIPS16e floating point.
