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. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Thomas Gleixner <tglx@linutronix.de>
