---------------------------
-What: PCMCIA control ioctl (needed for pcmcia-cs [cardmgr, cardctl])
-When: 2.6.35/2.6.36
-Files: drivers/pcmcia/: pcmcia_ioctl.c
-Why: With the 16-bit PCMCIA subsystem now behaving (almost) like a
- normal hotpluggable bus, and with it using the default kernel
- infrastructure (hotplug, driver core, sysfs) keeping the PCMCIA
- control ioctl needed by cardmgr and cardctl from pcmcia-cs is
- unnecessary and potentially harmful (it does not provide for
- proper locking), and makes further cleanups and integration of the
- PCMCIA subsystem into the Linux kernel device driver model more
- difficult. The features provided by cardmgr and cardctl are either
- handled by the kernel itself now or are available in the new
- pcmciautils package available at
- http://kernel.org/pub/linux/utils/kernel/pcmcia/
-
- For all architectures except ARM, the associated config symbol
- has been removed from kernel 2.6.34; for ARM, it will be likely
- be removed from kernel 2.6.35. The actual code will then likely
- be removed from kernel 2.6.36.

What: sys_sysctl
When: September 2010
Option: CONFIG_SYSCTL_SYSCALL
---------------------------
+What: /proc/<pid>/oom_adj
+When: August 2012
+Why: /proc/<pid>/oom_adj allows userspace to influence the oom killer's
+ badness heuristic used to determine which task to kill when the kernel
+ is out of memory.
+
+ The badness heuristic has since been rewritten since the introduction of
+ this tunable such that its meaning is deprecated. The value was
+ implemented as a bitshift on a score generated by the badness()
+ function that did not have any precise units of measure. With the
+ rewrite, the score is given as a proportion of available memory to the
+ task allocating pages, so using a bitshift which grows the score
+ exponentially is, thus, impossible to tune with fine granularity.
+
+ A much more powerful interface, /proc/<pid>/oom_score_adj, was
+ introduced with the oom killer rewrite that allows users to increase or
+ decrease the badness() score linearly. This interface will replace
+ /proc/<pid>/oom_adj.
+
+ A warning will be emitted to the kernel log if an application uses this
+ deprecated interface. After it is printed once, future warnings will be
+ suppressed until the kernel is rebooted.
+
+---------------------------
+
What: remove EXPORT_SYMBOL(kernel_thread)
When: August 2006
Files: arch/*/kernel/*_ksyms.c
Why: Should be implemented in userspace, policy daemon.
Who: Johannes Berg <johannes@sipsolutions.net>
----------------------------
-
-What: CONFIG_INOTIFY
-When: 2.6.33
-Why: last user (audit) will be converted to the newer more generic
- and more easily maintained fsnotify subsystem
-Who: Eric Paris <eparis@redhat.com>
-
----------------------------
What: sound-slot/service-* module aliases and related clutters in
----------------------------
-What: xtime, wall_to_monotonic
-When: 2.6.36+
-Files: kernel/time/timekeeping.c include/linux/time.h
-Why: Cleaning up timekeeping internal values. Please use
- existing timekeeping accessor functions to access
- the equivalent functionality.
-Who: John Stultz <johnstul@us.ibm.com>
-
-----------------------------
-
What: KVM paravirt mmu host support
When: January 2011
Why: The paravirt mmu host support is slower than non-paravirt mmu, both
----------------------------
+What: PCI DMA unmap state API
+When: August 2012
+Why: PCI DMA unmap state API (include/linux/pci-dma.h) was replaced
+ with DMA unmap state API (DMA unmap state API can be used for
+ any bus).
+Who: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp>
+
+----------------------------
+
+What: DMA_xxBIT_MASK macros
+When: Jun 2011
+Why: DMA_xxBIT_MASK macros were replaced with DMA_BIT_MASK() macros.
+Who: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp>
+
+----------------------------
+
+ What: iwlwifi disable_hw_scan module parameters
+ When: 2.6.40
+ Why: Hareware scan is the prefer method for iwlwifi devices for
+ scanning operation. Remove software scan support for all the
+ iwlwifi devices.
