Adds all defines, ioctls and structs needed for the sliced VBI API VBI = Vertical Blank Interval. It is related with the way TV signals work. It sends a line, then, it has a retrace time to allow the tube to move electrons to the beginning of the next line. This was the main reason at the beginning of analog B&W TV. There is a lot of bandwidth lost on VBI. So, lots of TV systems use it to send other information such as Closed Captions and Teletext. Also, broadcasters uses this as a channel to exchange information from the content producer to their subsidiaries at each city. There's already a raw VBI interface on V4L2 api, used for Closed Captions and Teletext. The decoding is doing at userlevel space and it is mostly for analog TV signals, non encoded. Encoded signals (MPEG, for example), may need also to transmit other information (like, for example, display aspect, i.e. 4x3, widescreen...). Sliced VBI interface is a method to allow the video stream to transmit this kind of information. Signed-off-by:

Change a printk(KERN_WARNING to dprintk, and it is really only interesting when trying to debug a problem, and can occur normally without error. Remove various gratuitous gotos in surrounding code, and remove some type-cast assignments from inside 'if' conditionals, as that is just obscuring what it going on. Signed-off-by:

In the case of a lock which introduces a new lockowner, the openowner's sequence id should be incremented, even when the operation fails, if the error is a sequence-id-mutating error. The current code fails to do that in some cases. Fix this by using the same sequence-id-incrementing mechanism that all other such operations use. Signed-off-by:

Demote some printk's that look like they could be triggered by non-buggy clients to dprintk's. (For example, stale clientid's are normal occurrences on reboot, and on a server with a lot of clients these messages could become annoying.) Also remove some redundant dprintk's (e.g. no need for both STALE_CLIENTID and its callers to do dprintks). Signed-off-by:

Add a input driver for the keyboard found on the Zaurus Cxx00 series (Spitz, Akita, Borzoi). Its based on corgikbd but there are enough subtle differences to justify a separate driver. Signed-Off-by:

Add the platform support code for two new Sharp Zaurus Models, Spitz (SL-C3000) and Borzoi (SL-C3100). This patch also adds most of the foundations for Akita (SL-C1000) Support. The missing link for Akita is the driver for its I2C io expander. Once this has been finished, the missing Kconfig option and machine declaration can easily be added to this code. Signed-Off-by:

Separate out the Sharp Zaurus c7x0 series specific code from the Corgi backlight driver. Abstract model/machine specific functions to corgi_lcd.c via sharpsl.h This enables the driver to be used by the Zaurus cxx00 series. Signed-Off-by:

Separate out the Sharp Zaurus c7x0 series specific code from the Corgi Touchscreen driver. Use the new functions in corgi_lcd.c via sharpsl.h for hsync handling and pass the IRQ as a platform device resource. Move a function prototype into the w100fb header file where it belongs. This enables the driver to be used by the Zaurus cxx00 series. Signed-Off-by:

The same LCD is present on both the Sharp Zaurus c7x0 series and the cxx00 but with different framebuffer drivers (w100fb vs. pxafb). This patch adds support for the cxx00 series to the LCD driver. It also adds some LCD to touchscreen interface logic needed by the touchscreen driver to prevent interference problems, the idea being to keep all the ugly code in one place leaving the drivers themselves clean. sharpsl.h is used to provide the abstraction.

Sharp's newer range of Zaurus clamshell handhelds, the cxx00's are similar to the c7x0 series yet different. This patch series abstracts the differences and generates a set of common drivers that support both series of devices. It then adds machine support for Spitz (SL-C3000) and Borzoi (SL-C3100). Hooks for Akita (SL-C1000) differences are also added. The I2C driver for its IO expander is the only missing piece. This patch: Separate out the Sharp Zaurus c7x0 series specific code from corgi_ssp.c so that other models such as the cxx00's can share it. Create sharpsl.h which will be used to abstract machine/model specifics. This enables the driver to be used by the Zaurus cxx00 series. Signed-Off-by:

This patch adds support for "One Button Disaster Recovery" devices to the cciss driver. (OBDR devices are tape drives which can pretend to be cd-rom devices temporarily. Once booted the device can be reverted to a tape drive and data recovery operations can be automatically begun.) This is an enhancement request by a vendor/partner working on One Button Disaster Recovery. Signed-off-by:

The CCISS driver seems to loose track of DMA mappings created by it's fill_cmd() routine. Neither callers of this routine are extracting the DMA address created in order to do the unmap. Instead, they simply try to unmap 0x0. It's easy to see this problem on an x86_64 system when using the "swiotlb=force" boot option. In this case, the driver is leaking resources of the swiotlb and not causing a sync of the bounce buffer. Signed-off-by:

This patch changes the way we complete commands. In the old method when we got a completion we searched our command list from the top until we find it. This method uses a tag associated with each command (not SCSI command tagging) to index us directly to the completed command. This helps performance. Signed-off-by:

This patch removes a couple of functions dealing with configuration and replaces them with new functions. This implementation fixes some bugs associated with the ACUXE. It also allows a logical volume to be removed from the middle without deleting all volumes behind it. If a user has 5 logical volumes and decides he wants to reconfigure volume number 3, he can now do that without removing volumes 4 & 5 first. This code has been tested in our labs against all application software. Signed-off-by:

This patch adds new PCI and subsystem ID's that finally made the spec. It also include a name change for one controller. I know there's a lot of duplicat names but the fw folks wanted this for the different implementations. Even though the same ASIC is used it may be embedded on some platforms, standup card in others, and a mezzanine in other servers. Signed-off-by:

reiserfs should use mark_inode_dirty during reiserfs_file_write and reiserfs_commit_write. This makes sure the inode is properly flagged as dirty, which is used during O_SYNC to decide when to trigger log commits. This patch also removes the O_SYNC check from reiserfs_commit_write, since that gets dealt with properly at higher layers once we start using mark_inode_dirty.

These functions don't need schedule_timeout()'s barrier. Signed-off-by:

Andrew Morton authored
Explain the mysteries of set_current_state(). Quoth Linus: The scheduler itself never needs the memory barrier at all. The barrier is needed only if the user itself ends up testing some other thing afterwards, ie if you have set_process_state(TASK_INTERRUPTIBLE); if (still_need_to_sleep()) schedule(); then the "still_need_to_sleep()" thing may test flags and wakeup events, and then you _may_ want to (and often do) make sure that the write of TASK_INTERRUPTIBLE is serialized wrt the reads of any wakeup data (since the wakeup may have happened on another CPU). So the comment is somewhat wrong. We don't really _care_ whether the state propagates out to other CPU's since all of our actions are purely local, and there is nothing we do that is conditional on any other CPU: we're going to sleep unconditionally, and the scheduler only cares about _our_ state, not about somebody elses state.

Force a compiler error instead of a link error, because they are easier to track down. Idea stolen from code by Jan Beulich <jbeulich@novell.com> If the argument to BUILD_BUG_ON evaluates to non-zero the compiler will do: t.c:6: error: size of array `type name' is negative (surprised that gcc doesn't have an extension for this) Signed-off-by:

When open(O_CREAT) is called and the error, ENFILE, is returned, the file may be created anyway. This is counter intuitive, against the SUS V3 specification, and may cause applications to misbehave if they are not coded correctly to handle this semantic. The SUS V3 specification explicitly states "No files shall be created or modified if the function returns -1.". The error, ENFILE, is used to indicate the system wide open file table is full and no more file structs can be allocated. This is due to an ordering problem. The entry in the directory is created before the file struct is allocated. If the allocation for the file struct fails, then the system call must return an error, but the directory entry was already created and can not be safely removed. The solution to this situation is relatively easy. The file struct should be allocated before the directory entry is created. If the allocation fails, then the error can be returned directly. If the creation of the directory entry fails, then the file struct can be easily freed. Signed-off-by:

Discard *.exit.text sections on runtime. We cannot do this on link time because of the way BUG macros are implemented. If "__exit function" calls one of those macros, __bug_table section will reference this function. This is similar to ".altinstructions" situation on i386. *.exit.data seems to be OK in this respect and is discarded on link time. Signed-off-by:
