The ioresources_init function in kernel/resource.c in the Linux kernel
through 4.7, as used in Android before 2016-08-05 on Nexus 6 and 7 (2013)
devices, uses weak permissions for /proc/iomem, which allows local users to
obtain sensitive information by reading this file, aka Android internal bug
28814213 and Qualcomm internal bug CR786116. NOTE: the permissions may be
intentional in most non-Android contexts.
