From 377ffbcc536a5a6666dc077395163ab149c02610 Mon Sep 17 00:00:00 2001 From: Suresh Siddha Date: Fri, 24 Aug 2012 14:12:58 -0700 Subject: x86, fpu: remove unnecessary user_fpu_end() in save_xstate_sig() Few lines below we do drop_fpu() which is more safer. Remove the unnecessary user_fpu_end() in save_xstate_sig(), which allows the drop_fpu() to ignore any pending exceptions from the user-space and drop the current fpu.
