 +What: ACPI hotkey driver (CONFIG_ACPI_HOTKEY)
 +When: 2.6.21
 +Why:  hotkey.c was an attempt to consolidate multiple drivers that use
 +      ACPI to implement hotkeys.  However, hotkeys are not documented
 +      in the ACPI specification, so the drivers used undocumented
 +      vendor-specific hooks and turned out to be more different than
 +      the same.
 +
 +      Further, the keys and the features supplied by each platform
 +      are different, so there will always be a need for
 +      platform-specific drivers.
 +
 +      So the new plan is to delete hotkey.c and instead, work on the
 +      platform specific drivers to try to make them look the same
 +      to the user when they supply the same features.
 +
 +      hotkey.c has always depended on CONFIG_EXPERIMENTAL

 +
 +---------------------------
 +
 +What: /sys/firmware/acpi/namespace
 +When: 2.6.21
 +Why:  The ACPI namespace is effectively the symbol list for
 +      the BIOS.  The device names are completely arbitrary
 +      and have no place being exposed to user-space.
 +
 +      For those interested in the BIOS ACPI namespace,
 +      the BIOS can be extracted and disassembled with acpidump
 +      and iasl as documented in the pmtools package here:
 +      http://ftp.kernel.org/pub/linux/kernel/people/lenb/acpi/utils
 +Who:  Len Brown <len.brown@intel.com>
 +
 +---------------------------
 +
+ What: ACPI procfs interface
+ When: July 2007
+ Why:  After ACPI sysfs conversion, ACPI attributes will be duplicated
+       in sysfs and the ACPI procfs interface should be removed.
+ Who:  Zhang Rui <rui.zhang@intel.com>
+ ---------------------------
 +What: /proc/acpi/button
 +When: August 2007
 +Why:  /proc/acpi/button has been replaced by events to the input layer
 +      since 2.6.20.
 +Who:  Len Brown <len.brown@intel.com>
 +
 +---------------------------
 +
 +What: JFFS (version 1)
 +When: 2.6.21
 +Why:  Unmaintained for years, superceded by JFFS2 for years.
