Subject: [PATCH v2 0/6] MIPS: math-emu: FP emulation fixes and improvements

From: Aleksandar Markovic <aleksandar.markovic@...tec.com>

v1->v2:

   - corrected a number of spelling and other minor mistakes in commit
     messages
   - rebased to the latest code

This series includes:

  - a fix for certain SIGILL program crashes on issuing a valid CMP
    instruction
  - a fix for RINT emulation inaccuracies
  - a fix for the output of CLASS.D instruction emulation
  - several FP emulation debugfs statistics improvements

The patches in this series are logically and physically independent on
the patches previously sent in "Misc" series. This means that these
two series can be applied independently, in any order.

Aleksandar Markovic (6):
  MIPS: math-emu: CMP.Sxxx.<D|S>: Prevent occurrences of SIGILL crashes
  MIPS: math-emu: RINT.<D|S>: Fix several problems by reimplementation
  MIPS: math-emu: CLASS.D: Zero bits 32-63 of the result
  MIPS: math-emu: Add FP emu debugfs statistics for branches
  MIPS: math-emu: Add FP emu debugfs clear functionality
  MIPS: math-emu: Add FP emu debugfs stats for individual instructions
