4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Josh Poimboeuf <jpoimboe@redhat.com>
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.
