From 662499d04b6bc73d0ecab0ab876bacd5bbe7d6a7 Mon Sep 17 00:00:00 2001 From: Kevin Hao Date: Sun, 14 Jul 2013 17:02:04 +0800 Subject: [PATCH] powerpc: Remove the redundant flush_fp_to_thread() in setup_sigcontext() In commit c6e6771b(powerpc: Introduce VSX thread_struct and CONFIG_VSX) we add a invocation of flush_fp_to_thread() before copying the FPR or VSR to users. But we already invoke the flush_fp_to_thread() in this function. So remove one of them.
