I don't care to have userland know about it. I'm just concerned with the
arch_has_block_step() definition being right. But, you did previously tell
me that userland can set its own MSR_SE via sigreturn or setcontext or
something. If it can set its own MSR_BE the same way, then perhaps
userland wants to know.
