sil24_interrupt() loads host->ports[i] into a local variable, validates it, and then loads the value again in the call to sil24_host_intr(). This patch replaces the second load by a reference to the local variable. This is safe since no side-effects have occurred since the initial load. It also improves readability since it makes it clear that the parameter to sil24_host_intr() is the same value which was just validated.

On some embedded platforms, such as blackfin, the gpio interrupt for IDE interface is designed to be triggered with high voltage. The gpio port should be configured properly by set_irq_type() when register the irq. This patch enable the generic pata platform driver to accept platform irq flags data.

This patch applies some trivial cleanups to sata_promise: - repair whitespace damage - correct comment at board_2057x_pata definition - pull SATAII TX4 support code out to separate functions - rename ata_nr to ata_no for consistency with libata's port_no - remove some init-time debug printks (requested by Jeff) This patch should cause no behavioural changes, except for the removed printks.

Fix various bugs in pio/mwdma mode programming. * Control bits in the timing register wasn't cleared properly while programming PIO mode. * MWDMA mode programming cleared the wrong part of control bits. * MWDMA mode programming cleared udma_mask even when the controller doesn't support UDMA.

Implement _GTM/_STM support. acpi_gtm is added to ata_port which stores _GTM parameters over suspend/resume cycle. A new hook ata_acpi_on_suspend() is responsible for storing _GTM parameters during suspend. _STM is executed in ata_acpi_on_resume(). With this change, invoking _GTF is safe on IDE hierarchy and acpi_sata check before _GTF is removed. ata_acpi_gtm() and ata_acpi_stm() implementation is taken from Alan Cox's pata_acpi implementation. ata_acpi_gtm() is fixed such that the result parameter is not shifted by sizeof(union acpi_object).

This patch reimplements ACPI invocation such that, instead of exporting ACPI details to the rest of libata, ACPI event handlers - ata_acpi_on_resume() and ata_acpi_on_devcfg() - are used. These two functions are responsible for determining whether specific ACPI method is used and when. On resume, _GTF is scheduled by setting ATA_DFLAG_ACPI_PENDING device flag. This is done this way to avoid performing the action on wrong device device (device swapping while suspended). On every ata_dev_configure(), ata_acpi_on_devcfg() is called, which performs _SDD and _GTF. _GTF is performed only after resuming and, if SATA, hardreset as the ACPI spec specifies. As _GTF may contain arbitrary commands, IDENTIFY page is re-read after _GTF taskfiles are executed. If one of ACPI methods fails, ata_acpi_on_devcfg() retries on the first failure. If it fails again on the second try, ACPI is disabled on the device. Note that successful configuration clears ACPI failed status. With all feature checks moved to the above two functions, do_drive_set_taskfiles() is trivial and thus collapsed into ata_acpi_exec_tfs(), which is now static and converted to return the number of executed taskfiles to be used by ata_acpi_on_resume(). As failures are handled properly, ata_acpi_push_id() now returns -errno on errors instead of unconditional zero.

This patch cleans up ata_acpi_exec_tfs() and its friends. * Rename taskfile_array to ata_acpi_gtf and make it __packed as it's used as argument to ACPI method, and use pointer to ata_acpi_gtf and number of taskfiles to represent _GTF taskfiles instead of a pointer casted into unsigned long and byte count. This makes argument re-checking in do_drive_set_taskfiles() unnecessary. * Pointer in void * not in unsigned long. * Clean up do_drive_get_GTF() error handling and make do_drive_get_GTF() return number of taskfiles on success, 0 if _GTF doesn't exist or doesn't contain valid ata. -errno on other errors. * Remove superflous check for acpi->buffer.pointer. * Update taskfile_load_raw() such that printed messages look similar to the messages printed by ata_eh_report(). * s/do_drive_get_GTF/ata_dev_get_GTF/ s/do_drive_set_taskfiles/ata_dev_set_taskfiles/ Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

* Add acpi_handle to ata_host and ata_port. Rename ata_device->obj_handle to ->acpi_handle and move it above such that it doesn't get cleared on reconfiguration. * Replace ACPI node association which ata_acpi_associate() which is called once during host initialization. Unlike the previous implementation, ata_acpi_associate() uses ATA_FLAG_ACPI_SATA to choose between IDE or SATA ACPI hierarchy and uses simple child look up instead of recursive walk to match the nodes. This is way safer and simpler.

Commit 1c710c89 added the utimensat() system call, but didn't handle the case of checking for the writability of the target right, when the target was a file descriptor, not a filename. We cannot use vfs_permission(MAY_WRITE) for that case, and need to simply check whether the file descriptor is writable. The oops from using the wrong function was noticed and narrowed down by Markus Trippelsdorf.

PIO4 is a maximum PIO mode supported by a driver. Using "255" as a max_mode argument to ide_get_best_pio_mode() could result in wrong timings being used by a driver (for "pio" equal to 5) or OOPS (for "pio" values > 5 && < 255).

The SiS966 has one additional PCI-ID 1180. If the chipset is using this PCI-ID, the primary channel is connected to the first PATA-port. The secondary channel is connected to SATA-ports in IDE emulation mode. The legacy IO-ports are used. The including of the PCI-ID into pata_sis is not sufficient, because the legacy driver in drivers/ide is initialized before pata_sis.

When cleaning up HIDP sessions, we currently close the ACL connection before deregistering the input device. Closing the ACL connection schedules a workqueue to remove the associated objects from sysfs, but the input device still refers to them -- and if the workqueue happens to run before the input device removal, the kernel will oops when trying to look up PHYSDEVPATH for the removed input device. Fix this by deregistering the input device before closing the connections.
