From 36fe6175be15d33fec7c6aa53e6e202ad44f0b25 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Thu, 23 Apr 2015 12:08:58 +0200 Subject: [PATCH] x86/fpu: Change __thread_clear_has_fpu() to 'struct fpu' parameter We do this to make the code more readable, and also to be able to eliminate task_struct usage from most of the FPU code.
