* [MTD] User interface to Protection RegistersNicolas Pitre2005-05-23
| | | | | | | | | | | This is implemented using a ioctl to switch the MTD char device into one of the different OTP "modes", at which point read/write/seek can operate on the selected OTP area. Also some extra ioctls to query for size and lock protection segments or groups. Some example user space utilities are provided.

* [MTD] Support for protection register support on Intel FLASH chipsNicolas Pitre2005-05-23
| | | | | | | | | | This enables support for reading, writing and locking so called "Protection Registers" present on some flash chips. A subset of them are pre-programmed at the factory with a unique set of values. The rest is user-programmable.

| * [PATCH] Driver Core: remove driver model detach_stateDavid Brownell2005-05-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver model has a "detach_state" mechanism that: - Has never been used by any in-kernel drive; - Is superfluous, since driver remove() methods can do the same thing; - Became buggy when the suspend() parameter changed semantics and type; - Could self-deadlock when called from certain suspend contexts; - Is effectively wasted documentation, object code, and headspace. This removes that "detach_state" mechanism; net code shrink, as well as a per-device saving in the driver model and sysfs.

| * [PATCH] Driver Core: pm diagnostics update, check for errorsDavid Brownell2005-05-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch includes various tweaks in the messaging that appears during system pm state transitions: * Warn about certain illegal calls in the device tree, like resuming child before parent or suspending parent before child. This could happen easily enough through sysfs, or in some cases when drivers use device_pm_set_parent(). * Be more consistent about dev_dbg() tracing ... do it for resume() and shutdown() too, and never if the driver doesn't have that method. * Say which type of system sleep state is being entered. Except for the warnings, these only affect debug messaging.

* | [PATCH] Avoid console spam with ext3 aborted journal.Stephen Tweedie2005-05-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Avoid console spam with ext3 aborted journal. ext3 usually reports error conditions that it detects in its environment. But when its journal gets aborted due to such errors, it can sometimes continue to report that condition forever, spamming the console to such an extent that the initial first cause of the journal abort can be lost. When the journal aborts, we put the filesystem into readonly mode. Most subsequent filesystem operations will get rejected immediately by checks for MS_RDONLY either in the filesystem or in the VFS. But some paths do not have such checks --- for example, if we continue to write to a file handle that was opened before the fs went readonly. (We only check for the ROFS condition when the file is first opened.) In these cases, we can continue to generate log errors similar to EXT3-fs error (device $DEV) in start_transaction: Journal has aborted for each subsequent write. There is really no point in generating these errors after the initial error has been fully reported. Specifically, if we're starting a completely new filesystem operation, and the filesystem is *already* readonly (ie. the ext3 layer has already detected and handled the underlying jbd abort), and we see an EROFS error, then there is simply no point in reporting it again.

* | [PATCH] Fix filp being passed through raw ioctl handlerStephen Tweedie2005-05-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Don't pass meaningless file handles to block device ioctls. The recent raw IO ioctl-passthrough fix started passing the raw file handle into the block device ioctl handler. That's unlikely to be useful, as the file handle is actually open on a character-mode raw device, not a block device, so dereferencing it is not going to yield useful results to a block device ioctl handler. Previously we just passed NULL; also not a value that can usefully be dereferenced, but at least if it does happen, we'll oops instead of silently pretending that the file is a block device, so NULL is the more defensive option here. This patch reverts to that behaviour. Noticed by Al Viro.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [PATCH] CPCI: update I have finally done some work to update the CompactPCI hotplug driver to fix some of the outstanding issues in 2.6: - Added adapter and latch status ops so that those files will get created by the current PCI hotplug core. This used to not be required, but seems to be now after some of the sysfs rework in the core. - Replaced slot list spinlock with a r/w semaphore to avoid any potential issues with sleeping. This quiets all of the runtime warnings. - Reworked interrupt driven hot extraction handling to remove need for a polling operator for ENUM# status. There are a lot of boards that only have an interrupt driven by ENUM#, so this lowers the bar to entry. - Replaced pci_visit_dev usage with better use of the PCI core functions. The new code is functionally equivalent to the previous code, but the use of pci_enable_device on insert needs to be investigated further, as I need to do some more testing to see if it is still necessary.

| | * [PATCH] libata: Prevent the interrupt handler from completing a command twiceAlbert Lee2005-05-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: During the libata CD-ROM stress test, sometimes the "BUG: timeout without command" error is seen. Root cause: Unexpected interrupt occurs after the ata_qc_complete() is called, but before the SCSI error handler. The interrupt handler is invoked before the SCSI error handler, and it clears the command by calling ata_qc_complete() again. Later when the SCSI error handler is run, the ata_queued_cmd is already gone, causing the "BUG: timeout without command" error. Changes: - Use the ATA_QCFLAG_ACTIVE flag to prevent the interrupt handler from completing the command twice, before the scsi_error_handler. Signed-off-by: Albert Lee <albertcc@tw.ibm.com>
