Run FP32 & FPXX code with hybrid FPRs


Linux Kernel Configuration
└─>Kernel hacking
└─>Run FP32 & FPXX code with hybrid FPRs
In linux kernel since version 3.19 (release Date: 2015-02-08)  
The hybrid FPR scheme is normally used only when a program needs to
execute a mix of FP32 & FP64A code, since the trapping & emulation
that it entails is expensive. When enabled, this option will lead
to the kernel running programs which use the FP32 & FPXX FP ABIs
using the hybrid FPR scheme, which can be useful for debugging

If unsure, say N.
