From 84564d1c76255ac6d5fb76c85818cb5961fad061 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 27 Apr 2018 09:10:12 +0200 Subject: Documentation/x86: remove a stray reference to pci-nommu.c This is just the minimal workaround. The file is mostly either stale and/or duplicative of Documentation/admin-guide/kernel-parameters.txt, but that is much more work than I'm willing to do right now.
