a259d53205 m68k/atari - ide: do not register interrupt if host->get_lock is set
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.

02aa2a3763 drivers: avoid format string in dev_set_name
Calling dev_set_name with a single paramter causes it to be handled as a
format string.  Many callers are passing potentially dynamic string
content, so use "%s" in those cases to avoid any potential accidents,
including wrappers like device_create*() and bdi_register().

dbee032295 ide: Fix ordering of procfs registry.
We must ensure that ide_proc_port_register_devices() occurs on an
interface before ide_proc_register_driver() executes for that
interfaces drives.

Therefore defer the registry of the driver device objects backed by
ide_bus_type until after ide_proc_port_register_devices() has run
and thus all of the drive->proc procfs directory pointers have been
setup.

086fa5ff08 block: Rename blk_queue_max_sectors to blk_queue_max_hw_sectors
The block layer calling convention is blk_queue_<limit name>.
blk_queue_max_sectors predates this practice, leading to some confusion.

Also introduce a temporary wrapper for backwards compability.  This can

0fb18c4777 Revert "ide: try to use PIO Mode 0 during probe if possible"
This reverts commit 6029336426.

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.c

And 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.

Add ide_host_enable_irqs() helper and use it in ide_host_register()

This should fix the problem with "screaming" shared IRQ on the first

on the second port) which was uncovered by my rework of the serialized
interfaces support.

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.

5f4417a156 ide: fix PowerMac bootup oops
PowerMac bootup with CONFIG_IDE=y oopses in ide_pio_cycle_time():
because "ide: try to use PIO Mode 0 during probe if possible" causes
pmac_ide_set_pio_mode() to be called before drive->id has been set.

Bart points out other places which now need drive->id set earlier,
so follow his advice to allocate it in ide_port_alloc_devices()
(using kzalloc_node, without error message, as when allocating drive)
and memset it for reuse in ide_port_init_devices_data().

Fixed in passing: ide_host_alloc() was missing ide_port_free_devices()
from an error path.

aa07573b2b ide: Fix host drivers that need IRQF_SHARED
commit 255115fb35 ("ide: allow host drivers to

ide_host.  Drivers can now set ide_port_info.irq_flags = IRQF_SHARED, while
init_irq() passes ide_host.irq_flags to request_irq().

Unfortunately ide_host.irq_flags is never set, causing (on ARAnyM):

| Uniform Multi-Platform E-IDE driver
| ide: Falcon IDE controller
| Probing IDE interface ide0...
| hda: Sarge m68k, ATA DISK drive
| init_irq: sa = 0
| ide0: disabled, unable to get IRQ 15
| ide0: failed to initialize IDE interface
| ide0: disabling port

Solve this by copying ide_port_info.irq_flags to ide_host.irq_flags in
ide_host_alloc().

This bug probably affects the following IDE host drivers:
  - buddha

  - falconide
  - gayle
  - ide-cs
  - macide
  - q40ide
  - scc_pata

e354c1d803 ide: remove IDE_ARCH_LOCK (v2)
* Add ->{get,release}_lock methods to struct ide_port_info
  and struct ide_host.

* Convert core IDE code, m68k IDE code and falconide support to use
  ->{get,release}_lock methods instead of ide_{get,release}_lock().

* Remove IDE_ARCH_LOCK.

v2:
* Build fix from Geert updating ide_{get,release}_lock() callers in
  falconide.c.

552d3a99bd ide: remove broken EXABYTENEST support
do_identify() marks EXABYTENEST device as non-present and frees
drive->id so enable_nest() has absolutely no chance of working.

The code was like this since at least 2.6.12-rc2 and nobody
has noticed so just remove broken EXABYTENEST support.
