[PATCH v99,00/13] Add support for pure microMIPS kernel.

["Steven J. Hill" <sjhill@mips.com>]

From: "Steven J. Hill" <sjhill@mips.com>

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

Douglas Leung (1):
  MIPS: microMIPS: Add vdso support.

Steven J. Hill (12):
  MIPS: microMIPS: Add support for microMIPS instructions.
  MIPS: Whitespace clean-ups after microMIPS additions.
  MIPS: microMIPS: Floating point support for 16-bit instructions.
  MIPS: microMIPS: Add support for exception handling.
  MIPS: microMIPS: Support handling of delay slots.
  MIPS: microMIPS: Add unaligned access support.
  MIPS: microMIPS: Add configuration option for microMIPS kernel.
  MIPS: microMIPS: Work-around for assembler bug.
  MIPS: microMIPS: Optimise 'memset' core library function.
  MIPS: microMIPS: Optimise 'strncpy' core library function.
  MIPS: microMIPS: Optimise 'strlen' core library function.
  MIPS: microMIPS: Optimise 'strnlen' core library function.
