* pata_sl82c105: remove un-needed code pathsAlan2007-02-211-30/+9
| | | | | | | | | Remove the DMA setup function. As pointed out by Sergey we set the actual DMA clock timing in set_dmamode so we don't actually need to do anything with it at set up time, but just leave the PIO timings loaded.

* libata: s/ap->id/ap->print_id/gTejun Heo2007-02-2110-52/+52
| | | | | | | | | | | | | | | | | | | | ata_port has two different id fields - id and port_no. id is system-wide 1-based unique id for the port while port_no is 0-based host-wide port number. The former is primarily used to identify the ATA port to the user in printk messages while the latter is used in various places in libata core and LLDs to index the port inside the host. The two fields feel quite similar and sometimes ap->id is used in place of ap->port_no, which is very difficult to spot. This patch renames ap->id to ap->print_id to reduce the possibility of such bugs. Some printk messages are adjusted such that id string (ata%u[.%u]) isn't printed twice and/or to use ata_*_printk() instead of hardcoded id format.

* sata_nv: enable hotplug interrupt and fix some readl/readw mismatchesRobert Hancock2007-02-211-8/+10
| | | | | | | | | | We already have code that handles hotplug interrupt indications in ADMA mode, this turns on the control flag that actually enables these interrupts.

* sata_nv: Use notifier for completion checksRobert Hancock2007-02-211-15/+7
| | | | | | | | | | | The hardware provides us a notifier register that indicates what command tags have completed. Use this to determine which CPBs to check, rather than blindly checking all active CPBs. This should provide a minor performance win, since if the controller has touched some of these incomplete CPBs, accessing them will likely result in a cache miss.

* libata: fix probe_ent alloc/free bugsTejun Heo2007-02-212-6/+2
| | | | | | | | | | | | | | | | ata_probe_ent_alloc() had a temporary hack such that devm_kzalloc() was used for allocation if devres had been previously initialized on the device; otherwise, plain kzalloc() was used. This was to make the code useable from both the old and devres-aware libata drivers during transition. This hack made ata_sas_port_alloc() unable to determine how the probe_ent is allocated, causing double free in some cases. Remove the now-unneeded hack and make ata_sas_port_alloc() use devm_kfree().

* libata bugfix: HDIO_DRIVE_TASKMark Lord2007-02-211-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | I was trying to use HDIO_DRIVE_TASK for something today, and discovered that the libata implementation does not copy over the upper four LBA bits from args[6]. This is serious, as any tools using this ioctl would have their commands applied to the wrong sectors on the drive, possibly resulting in disk corruption. Ideally, newer apps should use SG_IO/ATA_16 directly, avoiding this bug. But with libata poised to displace drivers/ide, better compatibility here is a must. This patch fixes libata to use the upper four LBA bits passed in from the ioctl. The original drivers/ide implementation copies over all bits except for the master/slave select bit. With this patch, libata will copy only the four high-order LBA bits, just in case there are assumptions elsewhere in libata (?).

* libata: put some intelligence into EH speed down sequenceTejun Heo2007-02-212-60/+125
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current EH speed down code is more of a proof that the EH framework is capable of adjusting transfer speed in response to error. This patch puts some intelligence into EH speed down sequence. The rules are.. * If there have been more than three timeout, HSM violation or unclassified DEV errors for known supported commands during last 10 mins, NCQ is turned off. * If there have been more than three timeout or HSM violation for known supported command, transfer mode is slowed down. If DMA is active, it is first slowered by one grade (e.g. UDMA133->100). If that doesn't help, it's slowered to 40c limit (UDMA33). If PIO is active, it's slowered by one grade first. If that doesn't help, PIO0 is forced. Note that this rule does not change transfer mode. DMA is never degraded into PIO by this rule. * If there have been more than ten ATA bus, timeout, HSM violation or unclassified device errors for known supported commands && speeding down DMA mode didn't help, the device is forced into PIO mode. Note that this rule is considered only for PATA devices and is pretty difficult to trigger. One error can only trigger one rule at a time. After a rule is triggered, error history is cleared such that the next speed down happens only after some number of errors are accumulated. This makes sense because now speed down is done in bigger stride. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* libata: improve probe failure handlingTejun Heo2007-02-212-37/+37
| | | | | | | | | | | | | | | | | | * Move forcing device to PIO0 on device disable into ata_dev_disable(). This makes both old and new EHs act the same way. * Speed down only PIO mode on probe failure. All commands used during probing are PIO commands. There's no point in speeding down DMA. * Retry at least once after -ENODEV. Some devices report garbled IDENTIFY data after certain events. This shouldn't cause device detach and re-attach. * Rearrange EH failure path for simplicity. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

| | | | | | | | | | | | | | | | | | | | Make ata_down_xfermask_limit() accept @sel instead of @force_pio0. @sel selects how the xfermask limit will be adjusted. The following selectors are defined. * ATA_DNXFER_PIO : only speed down PIO * ATA_DNXFER_DMA : only speed down DMA, don't cause transfer mode change * ATA_DNXFER_40C : apply 40c cable limit * ATA_DNXFER_FORCE_PIO : force PIO * ATA_DNXFER_FORCE_PIO0 : force PIO0 (same as original with @force_pio0 == 1) * ATA_DNXFER_ANY : same as original with @force_pio0 == 0 Currently, only ANY and FORCE_PIO0 are used to maintain the original behavior.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch stops "modpost" from issuing erroneous modpost warnings on ARM builds, which it's been doing since since maybe last summer. A canonical example would be driver method table entries: WARNING: <path> - Section mismatch: reference to .exit.text:<name>_remove from .data after '$d' (at offset 0x4) That "$d" symbol is generated by tools conformant with ARM ABI specs; in this case it's a symbol **in the middle of** a "<name>_driver" struct. The erroneous warnings appear to be issued because "modpost" whitelists references from "<name>_driver" data into init and exit sections ... but doesn't know should also include those "$d" mapping symbols, which are not otherwise associated with "<name>_driver" symbols. This patch prevents the modpost symbol lookup code from ever returning those mapping symbols, so it will return a whitelisted symbol instead. Then things work as expected. Now to revert various code-bloating "fixes" that got merged because of this modpost bug....

| | | | | | | | | | | | | | | | | | | | | | | Various bug fixes to the at91rm9200 RTC: - alarm: setalarm() should pay attention to the "enabled" flag - init: cleaner handling of the wakeup flags, which cpu init should really have set up. Doing it here is just a workaround. - linkage: since the at91_rtc driver probe() routine is in the init section, it should use platform_driver_probe() instead of leaving that pointer around in the driver struct after init section removal. - linkage: likewise, remove() belongs in the exit section. Among other things, the init and alarm changes ensure that this driver handles the new sysfs "wakealarm" attribute properly.

* [PATCH] rtc-sa1100 rtc_wklarm.enabled bugfixesDavid Brownell2007-02-201-5/+7
| | | | | | | | | | | | | | | | | | | | | Some rtc-sa1100 bugfixes: - The read_alarm() method reports the rtc_wkalrm.enabled field properly. This patch is already in the handhelds.org tree. - And the set_alarm() method now handles that flag correctly, rather than making mismatched {en,dis}able_irq_wake() calls, which trigger runtime warning messages. (Those calls are best made in suspend/resume methods.) Note that while this SA1100/PXA RTC is fully capable of waking those ARM processors from sleep states, that mechanism isn't properly supported on either processor family, or in this driver. Some boards have board-specific PM glue providing partial workarounds for the weak generic PM support.

* [PATCH] affs: implement ->drop_inodeChristoph Hellwig2007-02-203-6/+13
| | | | | | | | | | | | | affs wants to truncate the inode when the last user goes away, currently it does that through a potentially racy i_count check in ->put_inode. But we already have a method that's called just after the we dropped the last reference, ->drop_inode. This patch implements affs_drop_inode to take advantage of this.

* [PATCH] autofs4: check for directory re-create in lookupIan Kent2007-02-201-4/+19
| | | | | | | | | | | | | | | | This problem was identified and fixed some time ago by Jeff Moyer but it fell through the cracks somehow. It is possible that a user space application could remove and re-create a directory during a request. To avoid returning a failure from lookup incorrectly when our current dentry is unhashed we need to check if another positive, hashed dentry matching this one exists and if so return it instead of a fail.
