Subject[PATCH 00/68] ide2libata

Hi,

Here is a patchset (on top of atang-v3.1 tree) applying "out-of-the-box"
thinking to duplicated libata PATA and IDE subsystem host driver sets.
Namely, it modifies IDE API slightly to match libata's one more, adds
a tiny source-code level translation layer (ide2libata.h header file
which consists of only 17 lines of code) and then converts host drivers
to use shared source code for low-level operations (all drivers have
been carefully audited during porting to minimize the probability of
adding regressions accidentally). As an end result it is much easier
to maintain both driver sets (differences between 'new'/'old' drivers
are now apparent and there is no longer a need to manually back-port
many classes of bugfixes) and over 2500 LOC are gone.


The following changes since commit 7a4716f9084b32e32511cdea64ba538ac11e2c90:
