This series includes a few improvements to floating point support. The
first 2 patches add support for missing instructions to the FPU
emulator. The 3rd is a small cleanup. The 4th introduces support for
O32 binaries using 64-bit floating point. The 5th modifies the FPU
emulator to stop executing code from the user stack. The 6th & final
patch is not strictly FP-related but is a consequence of the 5th patch,
and allows us to mark the stack & allocated heap memory as
non-executable by default.

Leonid Yegoshin (1):
  mips: mfhc1 & mthc1 support for the FPU emulator

Paul Burton (4):
  mips: remove unused {en,dis}able_fpu macros
  mips: support for 64-bit FP with O32 binaries
  mips: use per-mm page to execute FP branch delay slots
  mips: non-exec stack & heap when non-exec PT_GNU_STACK is present

Steven J. Hill (1):
  mips: microMIPS: mfhc1 & mthc1 support for the FPU emulator
