+What: USER_SCHED
+When: 2.6.34
+
+Why: USER_SCHED was implemented as a proof of concept for group scheduling.
+ The effect of USER_SCHED can already be achieved from userspace with
+ the help of libcgroup. The removal of USER_SCHED will also simplify
+ the scheduler code with the removal of one major ifdef. There are also
+ issues USER_SCHED has with USER_NS. A decision was taken not to fix
+ those and instead remove USER_SCHED. Also new group scheduling
+ features will not be implemented for USER_SCHED.

+
+What: PRISM54
+When: 2.6.34
+
+Why: prism54 FullMAC PCI / Cardbus devices used to be supported only by the
+ prism54 wireless driver. After Intersil stopped selling these
+ devices in preference for the newer more flexible SoftMAC devices
+ a SoftMAC device driver was required and prism54 did not support
+ them. The p54pci driver now exists and has been present in the kernel for
+ a while. This driver supports both SoftMAC devices and FullMAC devices.
+ The main difference between these devices was the amount of memory which
+ could be used for the firmware. The SoftMAC devices support a smaller
+ amount of memory. Because of this the SoftMAC firmware fits into FullMAC
+ devices's memory. p54pci supports not only PCI / Cardbus but also USB
+ and SPI. Since p54pci supports all devices prism54 supports
+ you will have a conflict. I'm not quite sure how distributions are
+ handling this conflict right now. prism54 was kept around due to
+ claims users may experience issues when using the SoftMAC driver.
+ Time has passed users have not reported issues. If you use prism54
+ and for whatever reason you cannot use p54pci please let us know!

What: IRQF_SAMPLE_RANDOM

---------------------------
-What: libata spindown skipping and warning
-When: Dec 2008
-Why: Some halt(8) implementations synchronize caches for and spin
- down libata disks because libata didn't use to spin down disk on
- system halt (only synchronized caches).
- Spin down on system halt is now implemented. sysfs node
- /sys/class/scsi_disk/h:c:i:l/manage_start_stop is present if
- spin down support is available.
- Because issuing spin down command to an already spun down disk
- makes some disks spin up just to spin down again, libata tracks
- device spindown status to skip the extra spindown command and
- warn about it.
- This is to give userspace tools the time to get updated and will
- be removed after userspace is reasonably updated.

What: i386/x86_64 bzImage symlinks
When: April 2010

What (Why):
- - include/linux/netfilter_ipv4/ipt_TOS.h ipt_tos.h header files
- (superseded by xt_TOS/xt_tos target & match)
-
- - "forwarding" header files like ipt_mac.h in

-
- - xt_CONNMARK match revision 0
- (superseded by xt_CONNMARK match revision 1)

- (superseded by xt_MARK match revision 2)
-
- - xt_connmark match revision 0

-When: October 2009

- SCTP_GET_LOCAL_ADDRS_NUM_OLD, SCTP_GET_LOCAL_ADDRS_OLD
-When: June 2009
-Why: A newer version of the options have been introduced in 2005 that
- removes the limitions of the old API. The sctp library has been
- converted to use these new options at the same time. Any user
- space app that directly uses the old options should convert to using
- the new options.

-What: CONFIG_X86_OLD_MCE
-When: 2.6.32
-Why: Remove the old legacy 32bit machine check code. This has been
- superseded by the newer machine check code from the 64bit port,
- but the old version has been kept around for easier testing. Note this
- doesn't impact the old P5 and WinChip machine check handlers.

+
+What: sound-slot/service-* module aliases and related clutters in
+ sound/sound_core.c
+When: August 2010
+Why: OSS sound_core grabs all legacy minors (0-255) of SOUND_MAJOR
+ (14) and requests modules using custom sound-slot/service-*
+ module aliases. The only benefit of doing this is allowing
+ use of custom module aliases which might as well be considered
+ a bug at this point. This preemptive claiming prevents
+ alternative OSS implementations.
+
+ Till the feature is removed, the kernel will be requesting
+ both sound-slot/service-* and the standard char-major-* module
+ aliases and allow turning off the pre-claiming selectively via
+ CONFIG_SOUND_OSS_CORE_PRECLAIM and soundcore.preclaim_oss
+ kernel parameter.
+
+ After the transition phase is complete, both the custom module
+ aliases and switches to disable it will go away. This removal
+ will also allow making ALSA OSS emulation independent of
+ sound_core. The dependency will be broken then too.

+
+What: Support for VMware's guest paravirtuliazation technique [VMI] will be
+ dropped.
+When: 2.6.37 or earlier.
+Why: With the recent innovations in CPU hardware acceleration technologies
+ from Intel and AMD, VMware ran a few experiments to compare these
+ techniques to guest paravirtualization technique on VMware's platform.
+ These hardware assisted virtualization techniques have outperformed the
+ performance benefits provided by VMI in most of the workloads. VMware
+ expects that these hardware features will be ubiquitous in a couple of
+ years, as a result, VMware has started a phased retirement of this
+ feature from the hypervisor. We will be removing this feature from the
+ Kernel too. Right now we are targeting 2.6.37 but can retire earlier if
+ technical reasons (read opportunity to remove major chunk of pvops)
+ arise.
+
+ Please note that VMI has always been an optimization and non-VMI kernels
+ still work fine on VMware's platform.
+ Latest versions of VMware's product which support VMI are,
+ Workstation 7.0 and VSphere 4.0 on ESX side, future maintainence
+ releases for these products will continue supporting VMI.
+
+ For more details about VMI retirement take a look at this,

+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
+ only features that really need multiple path to guess what's
+ the right method name on a specific laptop.
+
+ Removing them will allow to remove a lot of code an significantly
+ clean the drivers.
+
+ This will affect the backlight code which won't be able to know
+ if the backlight is on or off. The platform display file will also be
+ write only (like the one in eeepc-laptop).
+
+ This should'nt affect a lot of user because they usually know
+ when their display is on or off.
