From 579e633e764e6e5f7784b74e7df3e81fe11f40de Mon Sep 17 00:00:00 2001 From: Anton Blanchard Date: Thu, 29 Oct 2015 11:44:09 +1100 Subject: powerpc: create flush_all_to_thread() Create a single function that flushes everything (FP, VMX, VSX, SPE). Doing this all at once means we only do one MSR write.
