Subject: [PATCH 4.14 119/140] x86/mm: Remove stale comment about KMEMCHECK

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

------------------

From: Jann Horn <jannh@...gle.com>

commit 3b3a9268bba62b35a29bafe0931715b1725fdf26 upstream.

This comment referred to a conditional call to kmemcheck_hide() that was
here until commit 4950276672fc ("kmemcheck: remove annotations").

Now that kmemcheck has been removed, it doesn't make sense anymore.
