Add capability for the user to clear all FP emu debugfs counters. This is achieved by having a special debugfs file "fpuemustats_clear" (under default location "/sys/kernel/debug/mips"). Each access to the file results in setting all counters to zero (it is enough, let's say, to issue a "cat /sys/kernel/debug/mips/fpuemustats_clear"). This functionality already exists for R2 emulation statistics, but was missing for FP emulation statistics. The implementation in this patch is consistent with its R2 emulation counterpart.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
