258What: GPIO autorequest on gpio_direction_{input,output}() in gpiolib
259When: February 2010
260Why: All callers should use explicit gpio_request()/gpio_free().
261 The autorequest mechanism in gpiolib was provided mostly as a
262 migration aid for legacy GPIO interfaces (for SOC based GPIOs).
263 Those users have now largely migrated. Platforms implementing
264 the GPIO interfaces without using gpiolib will see no changes.

324What: Ability for non root users to shm_get hugetlb pages based on mlock
325 resource limits
326When: 2.6.31
327Why: Non root users need to be part of /proc/sys/vm/hugetlb_shm_group or
328 have CAP_IPC_LOCK to be able to allocate shm segments backed by
329 huge pages. The mlock based rlimit check to allow shm hugetlb is
330 inconsistent with mmap based allocations. Hence it is being
331 deprecated.

408What: fakephp and associated sysfs files in /sys/bus/pci/slots/
409When: 2011
410Why: In 2.6.27, the semantics of /sys/bus/pci/slots was redefined to
411 represent a machine's physical PCI slots. The change in semantics
412 had userspace implications, as the hotplug core no longer allowed
413 drivers to create multiple sysfs files per physical slot (required
414 for multi-function devices, e.g.). fakephp was seen as a developer's
415 tool only, and its interface changed. Too late, we learned that
416 there were some users of the fakephp interface.
417
418 In 2.6.30, the original fakephp interface was restored. At the same
419 time, the PCI core gained the ability that fakephp provided, namely
420 function-level hot-remove and hot-add.
421
422 Since the PCI core now provides the same functionality, exposed in:
423
424 /sys/bus/pci/rescan
425 /sys/bus/pci/devices/.../remove
426 /sys/bus/pci/devices/.../rescan
427
428 there is no functional reason to maintain fakephp as well.
429
430 We will keep the existing module so that 'modprobe fakephp' will
431 present the old /sys/bus/pci/slots/... interface for compatibility,
432 but users are urged to migrate their applications to the API above.
433
434 After a reasonable transition period, we will remove the legacy
435 fakephp interface.
