+What:  Ability for non root users to shm_get hugetlb pages based on mlock

+When:  2.6.31
+Why:   Non root users need to be part of /proc/sys/vm/hugetlb_shm_group or
+       have CAP_IPC_LOCK to be able to allocate shm segments backed by

+What:  fakephp and associated sysfs files in /sys/bus/pci/slots/
+When:  2011
+Why:   In 2.6.27, the semantics of /sys/bus/pci/slots was redefined to
+       represent a machine's physical PCI slots. The change in semantics
+       had userspace implications, as the hotplug core no longer allowed
+       drivers to create multiple sysfs files per physical slot (required
+       for multi-function devices, e.g.). fakephp was seen as a developer's
+       tool only, and its interface changed. Too late, we learned that
+       there were some users of the fakephp interface.
+
+       In 2.6.30, the original fakephp interface was restored. At the same
+       time, the PCI core gained the ability that fakephp provided, namely
+       function-level hot-remove and hot-add.
+
+       Since the PCI core now provides the same functionality, exposed in:
+
+               /sys/bus/pci/rescan
+               /sys/bus/pci/devices/.../remove
+               /sys/bus/pci/devices/.../rescan
+
+       there is no functional reason to maintain fakephp as well.
+
+       We will keep the existing module so that 'modprobe fakephp' will
+       present the old /sys/bus/pci/slots/... interface for compatibility,
+       but users are urged to migrate their applications to the API above.
+
+       After a reasonable transition period, we will remove the legacy
+       fakephp interface.
