ide-2.6 update
Hi,
Here is late ide-2.6 update. Various small fixes (mainly for nasty
corner cases, from Tejun Heo) and few trivial cleanups for which I
see no reason to wait for 2.6.11. Please apply.
Bartlomiej

[ide] fix error handling in probe_hwif_init() and sgiioc4 driver
From: Prarit Bhargava <prarit@sgi.com>
I discovered an issue where a hwif_init() failure lead to /proc/ide files
being created for devices that failed probes. This resulted in
oops/WARN_ON/BUG_ON executions through the kernel depending on what
actions were on going.
slightly changed by me (bart)

[ide] add ide_hwgroup_t.polling

value, though slim, there's a chance that something can go
weird. And while at it, explicit jiffy comparisons are
converted to use time_before() macros.

[ide] __ide_do_rw_disk() return value fix
In __ide_do_rw_disk(), ide_started used to be returned blindly
after issusing PIO write. This can cause hang if
pre_task_out_intr() returns ide_stopped due to failed
ide_wait_stat() test. Fixed to pass the return value of
pre_task_out_intr().

[ide] cleanup piix
In drivers/ide/pci/piix.[hc], init_setup_piix() is defined and
used but only one init_setup function is defined and no
demultiplexing is done using init_setup callback. As other
drivers call ide_setup_pci_device() directly in such cases,
this patch removes init_setup_piix() and makes piix_init_one()
call ide_setup_pci_device() directly.

[ide] remove WAIT_READY dependency on APM
On the one hand APM isn't enabled on all laptops.
On the other hand, this also affects regular PCs with APM support (or
using a distribution kernel with APM support).
The time for the !APM case was already increased from 30msec in 2.4 .
Isn't there a timeout that is suitable for all cases?
Alan Cox answered:

Until someone has a real good solution (consider e.g. that most PC users
might have ACPI support enabled), this patch unconditionally sets
WAIT_READY to 5 seconds.
