From: Kevin Hao Date: Sun, 14 Jul 2013 09:02:04 +0000 (+0800) Subject: powerpc: Remove the redundant flush_fp_to_thread() in setup_sigcontext() X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=662499d04b6bc73d0ecab0ab876bacd5bbe7d6a7;p=openwrt%2Fstaging%2Fblogic.git 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.
