After a recent chat with Dave we agreed to try to finally kill off the
legacy IDE code base. Set a two year grace period in which we try
to move everyone over. There are a few pieces of hardware not
supported by libata yet, but for many of them we aren't even sure
if there are any users. For those that have users we have usually
found a volunteer to add libata support.Signed-off-by: Christoph Hellwig

There's an issue with how sense requests are handled in IDE. If ide-cd
encounters an error, it queues a sense request. With how IDE request
handling is done, this is the next request we need to handle. But it's
impossible to guarantee this, as another request could come in between
the sense being queued, and ->queue_rq() being run and handling it. If
that request ALSO fails, then we attempt to doubly queue the single
sense request we have.Since we only support one active request at the time, defer request
processing when a sense request is queued.Fixes: 600335205b8d "ide: convert to blk-mq"

The kmalloc() function has a 2-factor argument form, kmalloc_array(). This
patch replaces cases of:kmalloc(a * b, gfp)
with:
kmalloc_array(a * b, gfp)as well as handling cases of:
kmalloc(a * b * c, gfp)
with:
kmalloc(array3_size(a, b, c), gfp)
as it's slightly less ugly than:
kmalloc_array(array_size(a, b), c, gfp)
This does, however, attempt to ignore constant size factors like:
kmalloc(4 * 1024, gfp)
though any constants defined via macros get caught up in the conversion.
Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.The tools/ directory was manually excluded, since it has its own
implementation of kmalloc().The Coccinelle script used for this was:
// Fix redundant parens around sizeof().

that the dma_map routines now handle any required bounce buffering except

Pull timer updates from Thomas Gleixner:
"Yet another big pile of changes:- More year 2038 work from Arnd slowly reaching the point where we
need to think about the syscalls themself.- A new timer function which allows to conditionally (re)arm a timer
only when it's either not running or the new expiry time is sooner
than the armed expiry time. This allows to use a single timer for
multiple timeout requirements w/o caring about the first expiry
time at the call site.- A new NMI safe accessor to clock real time for the printk timestamp
work. Can be used by tracing, perf as well if required.- A large number of timer setup conversions from Kees which got
collected here because either maintainers requested so or they
simply got ignored. As Kees pointed out already there are a few
trivial merge conflicts and some redundant commits which was
unavoidable due to the size of this conversion effort.- Avoid a redundant iteration in the timer wheel softirq processing.
- Provide a mechanism to treat RTC implementations depending on their
hardware properties, i.e. don't inflict the write at the 0.5
seconds boundary which originates from the PC CMOS RTC to all RTCs.
No functional change as drivers need to be updated separately.- The usual small updates to core code clocksource drivers. Nothing

On m68k, host->get_lock is used to both lock and register the interrupt
that the IDE host shares with other device drivers. Registering the
IDE interrupt handler in ide-probe.c results in duplicating the
interrupt registered (once via host->get lock, and also via init_irq()),
and may result in IDE accepting interrupts even when another driver has
locked the interrupt hardware. This opens the whole locking scheme up
to races.host->get_lock is set on m68k only, so other drivers' behaviour is not
changed.Signed-off-by: Michael Schmitz

This reverts commit 6029336426a2b43e4bc6f4a84be8789a047d139e.
Ok, we really do need to revert this, even with Bart's sis5513.c
fix in there.The problem is that several driver's ->set_pio_mode() method
depends upon the drive->media type being set properly. Most
of them use this to enable prefetching, which can only be done
for disk media.But the commit being reverted here calls ->set_pio_mode() before
it's setup. Actually it considers everything disk because that
is the default media type set by ide_port_init_devices_data().The set of drivers that depend upon the media type in their
->set_pio_method() are:drivers/ide/alim15x3.c
drivers/ide/it8172.c
drivers/ide/it8213.c
drivers/ide/pdc202xx_old.c
drivers/ide/piix.c
drivers/ide/qd65xx.c
drivers/ide/sis5513.c
drivers/ide/slc90e66.cAnd it is possible that we could fix this by guarding the prefetching
and other media dependent setting changes with a test on
IDE_PFLAG_PROBING in hwif->port_flags, that's simply too risky for
2.6.32-rcX and -stable.Signed-off-by: David S. Miller

This reverts commit 24df31acaff8465d797f0006437b45ad0f2a5cb1.
The root cause of reported system hangs was (now fixed) sis5513 bug
and not "ide: try to use PIO Mode 0 during probe if possible" change
(commit 6029336426a2b43e4bc6f4a84be8789a047d139e) so the revert was
incorrect (it simply replaced one regression with the other one).Signed-off-by: Bartlomiej Zolnierkiewicz

This reverts commit 6029336426a2b43e4bc6f4a84be8789a047d139e.
Based upon a report by David Fries, wherein his system hangs
on bootup with sis5513 controller, right after the CDROM
is registered by ide-cd.c and the TOC is first read.Signed-off-by: David S. Miller

* Un-static __ide_wait_stat().
* Allow ide_dev_read_id() helper to be called from the IRQ context by
adding irq_ctx flag and using mdelay()/__ide_wait_stat() when needed.* 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
and clarity it is better to do it in a separate patch.Signed-off-by: Bartlomiej Zolnierkiewicz

Add ide_host_enable_irqs() helper and use it in ide_host_register()
before registering ports. Then remove no longer needed IRQ unmasking
from in init_irq().This should fix the problem with "screaming" shared IRQ on the first
port (after request_irq() call while we have the unexpected IRQ pending
on the second port) which was uncovered by my rework of the serialized
interfaces support.Reported-by: Frans Pop

In the near future, the driver core is going to not allow direct access
to the driver_data pointer in struct device. Instead, the functions
dev_get_drvdata() and dev_set_drvdata() should be used. These functions
have been around since the beginning, so are backwards compatible with
all older kernel versions.Cc: linux-ide@vger.kernel.org

Move the ack_intr() method into 'struct ide_port_ops', also renaming it to

* Add 'unsigned long port_flags' field to ide_hwif_t.
* Add IDE_PFLAG_PROBING port flag and keep it set during probing.
* Fix ide_pio_need_iordy() to not enable IORDY at a probe time
(IORDY may lead to controller lock up on certain controllers
if the port is not occupied).Loosely based on the recent libata's fix by Tejun, thanks to Alan
for the hint that IDE may also need it.Signed-off-by: Bartlomiej Zolnierkiewicz
