I'm fairly sure its not; its a rather invasive series; see:

2432e1364bbe x86: Nuke the supervisor_stack field in i386 thread_info
b807902a88c4 x86: Nuke GET_THREAD_INFO_WITH_ESP() macro for i386
0788aa6a23cb x86: Prepare removal of previous_esp from i386 thread_info structure
198d208df437 x86: Keep thread_info on thread stack in x86_32

Let me see if there's anything 'simpler' we can stuff in .13+
