From 35ff802af1c49dab21af8ef47b492ff952831d72 Mon Sep 17 00:00:00 2001 From: Guo Ren Date: Mon, 31 Dec 2018 01:19:29 +0800 Subject: csky: fixup remove vdsp implement for kernel. The vr regs for vdsp only saved in task_switch not in every exception trap-in. The memcpy with vdsp instructions will destroy the vr regs for user space applications.
