hdparm-9.2 now available: w/ DCO and firmware support

[Mark Lord <liml@rtr.ca>]

hdparm v9.2 is now available from sourceforge.

	http://sourceforge.net/projects/hdparm/

New since v8.9 are:

1. Support for Device Configuration Overlay (DCO),
   with the --dco-identify, --dco-freeze, and --dco-restore flags.
   DCO is a feature set that enables vendors/OEMs to disable/hide
   certain drive features (eg. NCQ, LBA48, ..) for whatever reason
   (eg. compatibility with a specific b0rked BIOS).
   This release of hdparm can display/reset DCO, but not selectively
   disable features yet.

2. Support for firmware download (upgrade) using the
   standard ATA DOWNLOAD_MICROCODE protocols 7 (preferred) and 3.
   This is initiated via the new --fwdownload flag,
   or the --fwdownload80 flag for a non-standard final packet
   (needed by some vendors).

3. Fixed WorldWideName display, and added cache-size display in -I output.

4. Detect/warn of kernel driver bugs in -N output.
   Eg. sata_sil24 misbehaves here in 2.6.25, but is fine in 2.6.27.

5. General fixes and tidiness in the sg16 routines.

Enjoy.
