From: Josh Poimboeuf jpoimboe@redhat.com Date: Mon, 18 Sep 2017 21:43:31 -0500 Subject: x86/head: Remove confusing comment
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.
