From 6c35585273b26a580b2e2ad3d6a7db282308eec5 Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Mon, 5 Dec 2005 13:47:25 +0000 Subject: [PATCH] MIPS: DSP: eleminate used_dsp. used_dsp was meant to be used like used_math - but since the FPU context is small and lazy context switching is a stupid idea on multiprocessors this idea only got halfway implemented and those bits are were now breaking ptrace.
