+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!
+ E-mail us at: linux-wireless@vger.kernel.org

-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: 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.
