+Subject: [PATCH] Fix CONFIG_X86_DEBUG_FPU build failure
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+When CONFIG_X86_DEBUG_FPU is defined the alternatives_patched symbol
+is pulled in as a dependency which results in a build failure.  To
+prevent this undefine CONFIG_X86_DEBUG_FPU to disable the WARN_ON_FPU()
+macro and rely on WARN_ON_ONCE debugging checks which were previously
+added.
