Subject: [PATCH] x86/mm: kill stray kernel fault handling comment


I originally tried to send this a couple days ago, but does not
appear to have made it to LKML.  Sorry if it's a duplicate.

I originally had matching user and kernel comments, but the kernel
one got improved.  Some errant conflict resolution kicked the commment
somewhere wrong.  Kill it.

Fixes: aa37c51b94 ("x86/mm: Break out user address space handling")
