---------------------------
What: PCMCIA control ioctl (needed for pcmcia-cs [cardmgr, cardctl])
-When: November 2005
+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 makes further cleanups and integration of the
+ 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/
-Who: Dominik Brodowski <linux@brodo.de>
+
+ 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.
+Who: Dominik Brodowski <linux@dominikbrodowski.net>
---------------------------
----------------------------
-What: adt7473 hardware monitoring driver
-When: February 2010
-Why: Obsoleted by the adt7475 driver.
-Who: Jean Delvare <khali@linux-fr.org>
-
----------------------------
What: Support for lcd_switch and display_get in asus-laptop driver
When: March 2010
Why: These two features use non-standard interfaces. There are the
----------------------------
-
What: corgikbd, spitzkbd, tosakbd driver
When: 2.6.35
Files: drivers/input/keyboard/{corgi,spitz,tosa}kbd.c
----------------------------
-
-----------------------------
+What: KVM memory aliases support
+When: July 2010
+Why: Memory aliasing support is used for speeding up guest vga access
+ through the vga windows.
+
+ Modern userspace no longer uses this feature, so it's just bitrotted
+ code and can be removed with no impact.
+Who: Avi Kivity <avi@redhat.com>
+
+----------------------------
+
+What: KVM kernel-allocated memory slots
+When: July 2010
+Why: Since 2.6.25, kvm supports user-allocated memory slots, which are
+ much more flexible than kernel-allocated slots. All current userspace
+ supports the newer interface and this code can be removed with no
+ impact.
+Who: Avi Kivity <avi@redhat.com>
+
+----------------------------
+
+What: KVM paravirt mmu host support
+When: January 2011
+Why: The paravirt mmu host support is slower than non-paravirt mmu, both
+ on newer and older hardware. It is already not exposed to the guest,
+ and kept only for live migration purposes.
+Who: Avi Kivity <avi@redhat.com>
+
+----------------------------
+
+What: "acpi=ht" boot option
+When: 2.6.35
+Why: Useful in 2003, implementation is a hack.
+ Generally invoked by accident today.
+ Seen as doing more harm than good.
+Who: Len Brown <len.brown@intel.com>
++
++----------------------------
++
+ What: iwlwifi 50XX module parameters
+ When: 2.6.40
+ Why: The "..50" modules parameters were used to configure 5000 series and
+ up devices; different set of module parameters also available for 4965
+ with same functionalities. Consolidate both set into single place
+ in drivers/net/wireless/iwlwifi/iwl-agn.c
+
+ Who: Wey-Yi Guy <wey-yi.w.guy@intel.com>
+
+ ----------------------------
+
+ What: iwl4965 alias support
+ When: 2.6.40
+ Why: Internal alias support has been present in module-init-tools for some
+ time, the MODULE_ALIAS("iwl4965") boilerplate aliases can be removed
+ with no impact.
