With ->write_devctl method call (which unmasks drive IRQ) preceding
SELECT_MASK() call there is really no need for the latter.
Moreover with the combination of HPT36x controller and the drive on
the quirk_drives[] list this can result in superfluous enable_irq()
call which in turn will trigger WARN() in __enable_irq().

We always call SELECT_MASK(drive, 0) after ide_dev_read_id() call
so there is no need to do it again in the error path.

[inspired by pata_icside]
Enabling/disabling of card IRQs is handled fine by IRQ and IDE
subsystems so there is no need for custom ->maskproc method.
Moreover icside_maskproc() would enable IRQ only if it was already
enabled [because of 'if (state->enabled && !mask)' check].

There are two sites where the flag is being changed: ide_retry_pc
and idetape_do_request. Both codepaths are protected by hwif->busy
(ide_lock_port) and therefore we shouldn't need the atomic accesses.

The driver's resetproc() method resets both channels at once -- most probably
by driving RESET- on them. Not only such reset can severely disturb concurrent
operations on another channel, it also ensues 2-second delay, while there's no
apparent reason why SRST reset being performed prior to resetproc() call needs
to be followed up by another reset.

The driver's dma_lost_irq() and dma_clear() methods call pdc202xx_reset()
which resets both channels at once -- most probably by driving RESET- on them.
Not only such reset can severely disturb concurrent operations on another
channel, it is also a clear overkill (especially in the first case) and is
completely unexpected and thus not properly handled by the IDE core in this
context (in the second case the usual SRST reset would most probably ensue
anyway though); it also causes quite arbitrary 2-second delay. Hence, use the
standard ide_dma_lost_irq() method and don't install the optional dma_clear()
method at all -- the driver should do well without this age-old cruft...

The driver's dma_test_irq() method, although tests some chip specific interrupt
bits, finally always relies on the SFF-8038i standard interrupt bit. I see no
point in testing the bits that are not trusted anyway -- the driver should be
fully able to use the standard method implemetation, ide_dma_test_irq().
With this change 'pdc202xx_dma_ops' finally becomes identical to 'sff_dma_ops',
and we can get rid of it...

From the perspective of most users of recent systems, disabling Host
Protected Area (HPA) can break vendor RAID formats, GPT partitions and
risks corrupting firmware or overwriting vendor system recovery tools.
Unfortunately the original (kernels < 2.6.30) behavior (unconditionally
disabling HPA and using full disk capacity) was introduced at the time
when the main use of HPA was to make the drive look small enough for the
BIOS to allow the system to boot with large capacity drives.
Thus to allow the maximum compatibility with the existing setups (using
HPA and partitioned with HPA disabled) we automically disable HPA if
any partitions overlapping HPA are detected. Additionally HPA can also
be disabled using the "nohpa" module parameter (i.e. "ide_core.nohpa=0.0"
to disable HPA on /dev/hda).
v2:
Fix ->resume HPA support.
While at it:
- remove stale "idebus=" entry from Documentation/kernel-parameters.txt

* Use ->probed_capacity to store native device capacity for ATA disks.

* Implement block device ->set_capacity method.
v2:

* According to the spec the SET MAX ADDRESS command shall be
immediately preceded by a READ NATIVE MAX ADDRESS command.
* Add ide_disk_hpa_{get_native,set}_capacity() helpers.
Together with the previous patch adding ->set_capacity block device
method this allows automatic disabling of Host Protected Area (HPA)

pdc202xx_reset() calls pdc202xx_reset_host() twice, for both channels, while
that function actually twiddles the single, shared software reset bit -- the
net effect is a duplicated reset and horrendous 4 second delay happening not
only on a channel reset but also when dma_lost_irq() and dma_clear() methods
are called. Fold pdc202xx_reset_host() into pdc202xx_reset(), fix printk(),
and move it before the actual reset...

Commit ac95beedf8bc97b24f9540d4da9952f07221c023 (ide: add struct ide_port_ops
(take 2)) erroneously converted the driver's dma_timeout() and dma_lost_irq()
methods to call the driver's resetproc() method regardless of whether it was
defined for this specific controller while it hadn't been defined and hence
called for PDC20246. So the dma_clear() method, the successor of dma_timeout(),
shouldn't exist and the dma_lost_irq() method should be standard for PDC20246.

Until now we have had a 1:1 mapping between storage device physical
block size and the logical block sized used when addressing the device.
With SATA 4KB drives coming out that will no longer be the case. The
sector size will be 4KB but the logical block size will remain
512-bytes. Hence we need to distinguish between the physical block size
and the logical ditto.
This patch renames hardsect_size to logical_block_size.

It is possible for ide-cd to ignore ide_error()'s return value under
some circumstances. Workaround it in ide_intr() and ide_timer_expiry()
by checking if there is a device/port reset pending currently.

Since 2.6.26 we support UDMA66 on ATAPI devices requiring IVB quirk:
commit 8588a2b732928b343233af9b1855705b8286bed4
("ide: add SH-S202J to ivb_list[]")
We also later added support for more such devices in:
commit e97564f362a93f8c248246c19828895950341252
("ide: More TSST drives with broken cable detection")
and in:
commit 3ced5c49bd2d1f2c7f769e3a54385883de63a652
("ide: add TSSTcorp CDDVDW SH-S202H to ivb_list[]")
It turns out that such devices lack cable detection altogether
(which in turn results in incorrect detection of 40-wire cables
by our current cable detection strategy) so always handle them
by trusting host-side cable detection only.
v2:
Model detection fixup from Martin.

In commit c3a4d78c580de4edc9ef0f7c59812fb02ceb037f, while introducing
rq->resid_len, the default value of residue count was changed from
full count to zero. The conversion was done under the assumption that
when a request fails residue count wasn't defined. However, Boaz and
James pointed out that this wasn't true and the residue count should
be preserved for failed requests too.
This patchset restores the original behavior by setting rq->resid_len
to blk_rq_bytes(rq) on request start and restoring explicit clearing
in affected drivers. While at it, take advantage of the fact that
rq->resid_len is set to full count where applicable.
* ide-cd: rq->resid_len cleared on pc success
* mptsas: req->resid_len cleared on success
* sas_expander: rsp/req->resid_len cleared on success
* mpt2sas_transport: req->resid_len cleared on success
* ide-cd, ide-tape, mptsas, sas_host_smp, mpt2sas_transport, ub: take
advantage of initial full count to simplify code
Boaz Harrosh spotted bug in resid_len initialization. Fixed as
suggested.
