From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: "Steven Rostedt (VMware)" Date: Thu, 12 Oct 2017 18:06:19 -0400 Subject: [PATCH] x86/fpu/debug: Remove unused 'x86_fpu_state' and 'x86_fpu_deactivate_state' tracepoints MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit CVE-2017-5754 Commit: d1898b733619 ("x86/fpu: Add tracepoints to dump FPU state at key points") ... added the 'x86_fpu_state' and 'x86_fpu_deactivate_state' trace points, but never used them. Today they are still not used. As they take up and waste memory, remove them.
