Subject: [git patches] IDE updates part 1
Hi,
Since it's "Merging Spree" again here goes the first IDE update for 2.6.26:
- couple of fixes and preparatory patches for IDE warm-plug support
- rework of PowerMac media-bay support ([un]register IDE devices instead of
[un]registering IDE interface)
- IDE warm-plug support, to warm-plug devices on a port 'idex':
# echo -n "1" > /sys/class/ide_port/idex/delete_devices
unplug old device(s) and plug new device(s)
#echo -n "1" > /sys/class/ide_port/idex/scan
done!
- ability to add new interfaces for ide-generic host driver through
/sys/class/ide_generic/add, i.e.
echo -n "0x168:0x36e:10" > /sys/class/ide_generic/add
- generic packet command representation for ATAPI (Borislav Petkov)
- scc_pata update (Akira Iguchi)
- misc stuff...
Because of the above changes some obsoleted/broken code can be removed
(~250 LOC) together with PPC specific hacks (~500 LOC).
Almost all patches have been in IDE tree (which is propagated to both
-mm and -next trees) since middle of February so they should be pretty
polished by now (extra thanks to Sergei Shtylyov for the hard work on
reviewing IDE patches).
Linus, please pull from:
