Masked FPU exceptions should obviously not happen in the first place, but if they do, ignoring them seems to be the right thing to do. Although there is no documentation available for Cyrix MII, I did find erratum F-7 for Winchip C6, "FPU instruction may result in spurious exception under certain conditions" which seems to indicate that this can happen. That would also explain the behaviour Ondrej Zary reported on the MII. Signed-off-by:

My patch "Separate pci bits out of struct device_node" (commit 1635317f) had the unfortunate side-effect that it stopped eeh_init() from working correctly. It needs the pointers set up by find_and_init_phbs(), but it was being called just before find_and_init_phbs(). That meant that we didn't enable EEH (pSeries PCI error recovery) on any devices, and that meant that on POWER5 systems, the hypervisor wouldn't let us enable memory or I/O space access to any devices, and their drivers got somewhat confused. This fixes it by moving the eeh_init call after find_and_init_phbs. Tested on a POWER5 partition. Signed-of-by:

Some adjustments to the matroxfb code, for one part preventing the display to be disabled for longer than necessary, and for the other part to make information about the frame buffer position available so that a kernel debugger might obtain that before the initial mode change. Finally, some return code corrections to fit the generic fb code. Signed-off-by:

const-ify the font control structures and data, to make somewhat better guarantees that these are not modified anywhere in the kernel. Specifically for a kernel debugger to share this information from the normal kernel code, such a guarantee seems rather desirable. Signed-off-by:

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 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.)

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:
