Subject: x86/head: Remove confusing comment
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9cf5a88b165e203d8c7d5284640ea6aa61baf78a;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

x86/head: Remove confusing comment

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.
