[PATCH 1/4] ata_piix: ICH7 does not support correct MWDMA timings

[Alan Cox]

From: Alan Cox <alan@linux.intel.com>

See Errata documentation. The recommended workaround is to use PIO4 instead
which will we automatically do by flagging this mode not available.

[PATCH 3/4] ata_piix: Turn on hotplugging support for older chips

[Alan Cox]

From: Alan Cox <alan@linux.intel.com>

We can't do this for the later ones as they have all sorts of magic boot
time stuff that needs reviewing and the like. However we can do it for the
older ones and it turns out we need to as some IBM docking stations have a
second PIIX series device in them and without this change you can't use it
very well

[PATCH 4/4] ata_piix: Remove stale comment

[Alan Cox]

From: Alan Cox <alan@linux.intel.com>

Combined mode pci quirk hacks went away - so the table to keep in sync
no longer exists.

I guess 1 & 2 are #upstream-fixes material, and 3 & 4 are #upstream ?

I'd say they are all fixes. In terms of urgency #4 hasn't been reported
by anyone it was found when checking errata, #3 is a real problem
encountered by users #2 affects only fairly obscure hardware and isn't a
regression, #1 is a comment.

I've also now confirmed with the Intel hardware folks that there isn't
any reason we can't turn on parallel probing in ata_piix.

I was referring to the patch numbering provided by you, in your 
submission, which is the reverse of the order listed above:

patch #1: ICH7 MWDMA timings
patch #2: TZ90
patch #3: turn on hotplugging
patch #4: fix comment

patch #3 is a behavior change IMO very late in -rc cycle, and patch #4 
is not urgent.

Agreed - sorry I'd forgotten that stgit is quite creative with its
ordering.
