The legay ide driver has been replace with libata starting in 2003 and has
been scheduled for removal for a while. Finally kill it off so that we
can start cleaning up various bits of cruft it forced on the block layer.

* Switch ide_driveid_update() to set irq_ctx flag.
This change is needed for the consecutive patch which fixes races in
handling of user-space SET XFER commands but for improved bisectability

There are some broken devices that report multiple DMA xfer modes
enabled at once (ATA spec doesn't allow it) but otherwise work fine
with DMA so just delete ide_id_dma_bug().
[ As discovered by detective work by Frans and Bart, due to how
handling of the ID block was handled before commit c419993
("ide-iops: only clear DMA words on setting DMA mode") this
check was always seeing zeros in the fields or other similar
garbage. Therefore this check wasn't actually checking anything.
Now that the tests actually check the real bits, all we see are
devices that trigger the check yet work perfectly fine, therefore
killing this useless check is the best thing to do. -DaveM ]

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.
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().

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.

Simplify tf_read() method, making it deal only with 'struct ide_taskfile' and
the validity flags that the upper layer passes, and factoring out the code that
deals with the high order bytes into ide_tf_readback() to be called from the
only two functions interested, ide_complete_cmd() and ide_dump_sector().
This should stop the needless code duplication in this method and so make
it about twice smaller than it was; along with simplifying the setup for
the method call, this should save both time and space...

It seems that on some nVidia controllers using AltStatus register
can be unreliable so default to Status register if the PCI device
is in Compatibility Mode. In order to achieve this:
* Add ide_pci_is_in_compatibility_mode() inline helper to <linux/ide.h>.
* Add IDE_HFLAG_BROKEN_ALTSTATUS host flag and set it in amd74xx host
driver for nVidia controllers in Compatibility Mode.
* Teach actual_try_to_identify() and drive_is_ready() about the new flag.
This fixes the regression caused by removal of CONFIG_IDEPCI_SHARE_IRQ
config option in 2.6.25 and using AltStatus register unconditionally when
available (kernel.org bugs #11659 and #10216).
[ Moreover for CONFIG_IDEPCI_SHARE_IRQ=y (which is what most people
and distributions use) it never worked correctly. ]
Thanks to Remy LABENE and Lars Winterfeld for help with debugging the problem.

Apparently, there is no sense in unmasking IRQ on the controller when you call
disable_irq_nosync() before doing this, set the nIEN bit afterwards, and then
unmask IRQ again after the command completion, hence 0 passed to SELECT_MASK()
before issuing the command in ide_config_drive_speed() is probably just a typo.

On user request (through sysfs), the IDLE IMMEDIATE command with UNLOAD
FEATURE as specified in ATA-7 is issued to the device and processing of
the request queue is stopped thereafter until the specified timeout
expires or user space asks to resume normal operation. This is supposed
to prevent the heads of a hard drive from accidentally crashing onto the
platter when a heavy shock is anticipated (like a falling laptop expected
to hit the floor). Port resets are deferred whenever a device on that
port is in the parked state.

v4:
Fix a memory leak due to a missing blk_put_request() in
issue_park_cmd(). Additionally, we should plug the queue when enqueueing
the unpark request because there is no guarantee that the park timeout
has not expired by then. Even though the chance for that to happen is
very slim, the request might end up hanging in the queue until the next
I/O operation is queued up. While at it, clean up the code a little:
- make issue_park_cmd() a function of type void since nobody cares for
the return value anyway;
- use blk_start_queueing() instead of __blk_run_queue() since we don't
have to worry about recursion;
- remove a superfluous pointer deference in task_no_data_intr().

It turned out that probing order change causes problems for some drives:
http://bugzilla.kernel.org/show_bug.cgi?id=10239
Since root causes are still being investigated and are unlikely to be fixed
before 2.6.25 lets revert this change for now. As a result cable detection
becomes less reliable when compared with 2.6.24 but the affected drives are
useable again.

* ide_xfer_verbose() fixups:
- beautify returned mode names
- fix PIO5 reporting
- make it return 'const char *'
* Change printk() level from KERN_DEBUG to KERN_INFO in ide_find_dma_mode().
* Add ide_id_dma_bug() helper based on ide_dma_verbose() to check for invalid
DMA info in identify block.
* Use ide_id_dma_bug() in ide_tune_dma() and ide_driveid_update().
As a result DMA won't be tuned or will be disabled after tuning if device
reports inconsistent info about enabled DMA mode (ide_dma_verbose() does the
same checks while the IDE device is probed by ide-{cd,disk} device driver).
* Remove no longer needed ide_dma_verbose().
This patch should fix the following problem with out-of-sync IDE messages
reported by Nick Warne:
hdd: ATAPI 48X DVD-ROM DVD-R-RAM CD-R/RW drive, 2048kB Cache<7>hdd:
skipping word 93 validity check
, UDMA(66)
and later debugged by Mark Lord to be caused by:
ide_dma_verbose()
printk( ... "2048kB Cache");
eighty_ninty_three()
printk(KERN_DEBUG "%s: skipping word 93 validity check\n");
ide_dma_verbose()
printk(", UDMA(66)"
Please note that as a result ide-{cd,disk} device drivers won't report the
DMA speed used but this is intended since now DMA mode being used is always
reported by IDE core code.
v2:
* fixes suggested by Randy:
- use KERN_CONT for printk()-s in ide-{cd,disk}.c
- don't remove argument name from ide_xfer_verbose() declaration
v3:
* Remove incorrect check for (id->field_valid & 1) from ide_id_dma_bug()

* "XFER SLOW" -> "PIO SLOW" in ide_xfer_verbose() (suggested by Sergei).
* Fix ide_find_dma_mode() to report the correct mode ('mode' after being

Use ide_config_drive_speed() instead of pmac_ide_do_setfeature() and remove
the latter, also ide-iops.c::__ide_wait_stat() could be static again.
Since for IDE PMAC host driver IDE_CONTROL_REG is always true, device's
->quirk_list is always zero and ->ide_dma_host_{on,off} are nops than
the only changes in behavior are:
* if PIO mode is set then ->dma_off_queitly is called to disable DMA
* if setting transfer mode fails ide_dump_status() is called to dump status
v2:
* IDE PMAC controllers allow separate PIO and DMA timings and PPC userland
depends on this fact, and calls "hdparm -p" without calling "hdparm -d".
Therefore to compensate for DMA being disabled by ide_config_drive_speed()
for PIO modes:
- add IDE_HFLAG_SET_PIO_MODE_KEEP_DMA flag and set it in PMAC host driver
- add handling of the new flag to ide-io.c::do_special()

This patch allows users to override both host and device side cable detection
with "ideX=ata66" kernel parameter. Thanks to this it should be now possible
to use UDMA > 2 modes on systems (laptops mainly) which use short 40-pin cable
instead of 80-pin one.
Next patches add automatic detection of some systems using short cables.
Changes:
* Rename hwif->udma_four to hwif->cbl and make it u8.
* Convert all existing users accordingly (use ATA_CBL_* defines while at it).
* Add ATA_CBL_PATA40_SHORT support to ide-iops.c:eighty_ninty_three().
* Use ATA_CBL_PATA40_SHORT for "ideX=ata66" kernel parameter.

Tejun's recent eighty_ninty_three() fix has inspired me to do more thorough
review of the cable detection code...
* print user-friendly warning about limiting the maximum transfer speed
to UDMA33 (and the reason behind it) when 80-wire cable is not detected,
also while at it cleanup eighty_ninty_three() a bit
* use eighty_ninty_three() in ide_ata66_check(), this actually fixes 3 bugs:
- bit 14 (word 93 validity check) == 1 && bit 13 (80-wire cable test) == 1
were used as 80-wire cable present test for CONFIG_IDEDMA_IVB=n case
(please see FIXME comment in eighty_ninty_three() for more details)
- CONFIG_IDEDMA_IVB=y/n cases were interchanged
- check for SATA devices was missing
* remove private cable warnings from pdc_202xx{old,new} drivers now that core
code provides this functionality (plus, in pdc202xx_new case the test could
give false warnings for ATAPI devices because pdc202xx_new driver doesn't

already handled
It is possible for the timer expiry function to run even though the
request has already been handled: ide_timer_expiry() only checks that
the handler is not NULL, but it is possible that we have handled a
request (thus clearing the handler) and then started a new request
(thus starting the timer again, and setting a handler).
A simple way to exhibit this is to set the DMA timeout to 1 jiffy and
run dd: The kernel will panic after a few minutes because
ide_timer_expiry() tries to add a timer when it's already active.
To fix this, we simply add a request generation count that gets
incremented at every interrupt, and check in ide_timer_expiry() that
we have not already handled a new interrupt before running the expiry
function.

IDE error recovery is using IDLE IMMEDIATE if the drive is busy or has DRQ set.
This violates the ATA spec (can only send IDLEÂ IMMEDIATE when drive is not
busy) and really hoses up some drives (modern drives will not be able to
recover using this error handling). The correct thing to do is issue a SRST
followed by a SET FEATURES command. This is what Western Digital recommends
for error recovery and what Western Digital says Windows does.  It also does
not violate the ATA spec as far as I can tell.
Bart:
* port the patch over the current tree
* undo the recalibration code removal
* send SET FEATURES command after checking for good drive status
* don't check whether the current request is of REQ_TYPE_ATA_{CMD,TASK}
type because we need to send SET FEATURES before handling any requests
* some pre-ATA4 drives require INITIALIZE DEVICE PARAMETERS command before
other commands (except IDENTIFY) so send SET FEATURES only if there are
no pending drive->special requests
* update comments and patch description
* any bugs introduced by this patch are mine and not Suleiman's :-)

"ide: fix drive side 80c cable check, take 2" patch from Tejun Heo (commit
fab59375b9543f84d1714f7dd00f5d11e531bd3e) fixed 80c bit test (bit13 of word93)
but we also need to fix master/slave IDENTIFY order (slave device should be
probed first in order to make it release PDIAG- signal) and we should also
check for pre-ATA3 slave devices (which may not release PDIAG- signal).
[ Unfortunately the fact that IDE driver doesn't reset devices itself helps
only a bit as it seems that some BIOS-es reset ATA devices after programming
the chipset, some BIOS-es can be set to not probe/configure selected devices,
there may be no BIOS in case of add-on cards etc. ]
Since we are quite late in the release cycle and the required changes will
affect a lot of systems just revert the fix for now.
[ Please also see libata commit f31f0cc2f0b7527072d94d02da332d9bb8d7d94c. ]
Thanks goes out to Fernando Mitio Yamada for reporting the problem
and patiently testing patches.

eighty_ninty_three() had word 93 validitity check but not the 80c bit
test itself (bit 13). This increases the chance of incorrect wire
detection especially because host side cable detection is often
unreliable and we sometimes soley depend on drive side cable
detection. Fix it.

This results in smaller/faster/simpler code and allows future optimizations.

Michal Miroslaw reported a problem (bugzilla #7023) where a user initiated
reset while the IDE layer was already resetting the channel caused a crash,
and provided a rough fix.
This is a slightly cleaner version of the fix which tracks the reset state
and blocks further reset requests while a reset is in progress.
Note this is not a security issue - random end users can't access the
ioctl in question anyway.

When resuming from suspend-to-RAM, the NMI watchdog detects a lockup in
ide_wait_not_busy. Here's a screenshot of the trace taken by a digital
camera: http://www.uamt.feec.vutbr.cz/rizeni/pom/DSC03510-2.JPG
Let's touch the NMI watchdog in ide_wait_not_busy. The system then resumes
correctly from STR.

This is based on the proposed patches flying around but also checks that
the device in question is new enough to have word 93 rather thanb blindly
assuming word 93 == 0 means SATA (see ATA-5, ATA-7)

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
