From 9eff02e2042f96fb2aedd02e032eca1c5333d767 Mon Sep 17 00:00:00 2001 From: Jesse Barnes Date: Fri, 24 Oct 2008 10:32:33 -0700 Subject: PCI: check mmap range of /proc/bus/pci files too /proc/bus/pci allows you to mmap resource ranges too, so we should probably be checking to make sure the mapping is somewhat valid. Uses the same code as the recent sysfs mmap range checking patch from Linus.
