4.14-stable review patch. If anyone has any objections, please let me know.

commit 17270717e80de33a884ad328fea5f407d87f6d6a upstream.
This comment is actively wrong and confusing. It refers to the registers' stack offsets after the pt_regs has been constructed on the stack, but this code is *before* that.
At this point the stack just has the standard iret frame, for which no comment should be needed.
