* USB HID: numlock quirk for dell W7658 keyboardPete Zaitcev2007-04-111-0/+45
| | | | | | | | | | | | On Dell W7658 keyboard, when BIOS sets NumLock LED on, it survives the takeover by kernel and thus confuses users. Eating of an increasibly scarce quirk bit is unfortunate. We do it for safety, given the history of nervous input devices which crash if anything unusual happens. Signed-off-by: Pete Zaitcev <zaitcev@redhat.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
* USB HID: Logitech MX3000 keyboard needs report descriptor quirkJiri Kosina2007-04-112-12/+30
| | | | | | | | | | | Logitech MX3000 contains report descriptor which doesn't cover usages above 0x28c, but emits such usages. Report descriptor needs fixing in the very same way as with receivers shipped with S510 keyboards. This patch also adds a few mappings for multimedia keys that S510 didn't emit.

| | | | | | | | | | | Add HID_QUIRK_HIDDEV for the Belkin Flip USB KVM, which provides for software control of switching via a HID class interface. It overloads three HID LED usages, two of which aren't mapped in the ev_dev input subsection, and which it doesn't make sense to map.

* USB HID: fix retry & reset logicAlan Stern2007-04-111-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The USB HID driver fails to reset its error-retry timeout when there has been a long time interval between I/O errors with no successful URB completions in the meantime. As a result, the very next error would trigger an immediate reset, even if it was a chance event occurring long after the previous error. More USB keyboards and mice than one might expect end up getting I/O errors. Almost always this results from hardware problems of one sort of another. For example, people attach the device to a USB extension cable, which degrades the signal. Or they simply have poor quality cables to begin with. Or they use a KVM switch which doesn't handle USB messages correctly. Etc... There have been reports from several users in which these I/O errors would occur more or less randomly, at intervals ranging from seconds to minutes. The error-handling code in hid-core.c was originally meant for situations where a single outage would persist for a few hundred ms (electromagnetic interference, for example). It didn't work right when these more sporadic errors occurred, because of a flaw in the logic which this patch fixes. This patch (as873) fixes that oversight.

It can cause device-mapper to receive a different major from earlier kernels and it turns out that the Amanda backup program (via GNU tar, apparently) checks major numbers on files when performing incremental backups.

So for lba48 commands, tf_read() won't be reading back the full lba48 register contents.. Correct? This patch corrects fill_result_tf() so that the flags get copied to result_tf before they are used by tf_read().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If you set the IFF_ALLMULTI flag on a b44 device, or if you join more than B44_MCAST_TABLE_SIZE multicast groups, the device will stop receiving unicast messages. This is because the __b44_set_mac_addr call sets the zeroth CAM entry to the MAC address of the device, and then the loop at line 1722 proceeds to overwrite it unless the value of i is set by the __b44_load_mcast call. However, when IFF_ALLMULTI is set, that call is bypassed, leaving i set to zero. Fixed by starting the loop at 1 to make it skip the CAM entry for the MAC address.

* | [PATCH] msi: synchronously mask and unmask msi-x irqs.Eric W. Biederman2007-04-031-0/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a simplified and actually more comprehensive form of a bug fix from Mitch Williams <mitch.a.williams@intel.com>. When we mask or unmask a msi-x irqs the writes may be posted because we are writing to memory mapped region. This means the mask and unmask don't happen immediately but at some unspecified time in the future. Which is out of sync with how the mask/unmask logic work for ioapic irqs. The practical result is that we get very subtle and hard to track down irq migration bugs. This patch performs a read flush after writes to the MSI-X table for mask and unmask operations. Since the SMP affinity is set while the interrupt is masked, and since it's unmasked immediately after, no additional flushes are required in the various affinity setting routines. The testing by Mitch Williams on his especially problematic system should still be valid as I have only simplified the code, not changed the functionality. We currently have 7 drivers: cciss, mthca, cxgb3, forceth, s2io, pcie/portdrv_core, and qla2xxx in 2.6.21 that are affected by this problem when the hardware they driver is plugged into the right slot. Given the difficulty of reproducing this bug and tracing it down to anything that even remotely resembles a cause, even if people are being affected we aren't likely to see many meaningful bug reports, and the people who see this bug aren't likely to be able to reproduce this bug in a timely fashion. So it is best to get this problem fixed as soon as we can so people don't have problems. Then if people do have a kernel message stating "No irq for vector" we will know it is yet another novel cause that needs a complete new investigation.

Basically the stack frame of scsi_send_eh_cmd() is what ends up in the sense buffer. Depending upon how pointers look on a given platform, you can end up getting sr_ioctl.c errors when you mount a cdrom. If the CDROM gives a check condition for GPCMD_GET_CONFIGURATION issued by drivers/cdrom/cdrom.c:cdrom_mmc_profile(), sr_ioctl will spit out this error message in sr_do_ioctl() with the way pointers are on sparc64: default: printk(KERN_ERR "%s: CDROM (ioctl) error, command: ", cd->cdi.name); __scsi_print_command(cgc->cmd); scsi_print_sense_hdr("sr", &sshdr); err = -EIO; This is the error Tom Callaway reported in: http://marc.info/?l=linux-sparc&m=117407453208101&w=2 Anyways, fix this by using page_address(sgl.page) which is OK because we know this is low-mem due to GFP_ATOMIC.

* | [PATCH] vt: fix potential race in VT_WAITACTIVE handlerMichal Januszewski2007-04-021-2/+14
| | | | | | | | | | | | | | | | | | | | | | | | On a multiprocessor machine the VT_WAITACTIVE ioctl call may return 0 if fg_console has already been updated in redraw_screen() but the console switch itself hasn't been completed. Fix this by checking fg_console in vt_waitactive() with the console sem held.

* | [PATCH] rtc-cmos lockdep fix, irq updatesDavid Brownell2007-04-021-17/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Lockdep reported cmos_suspend() and cmos_resume() calling rtc_update_irq() with IRQs enabled; not allowed. Also fix problems seen on some hardware, whereby false alarm IRQs could be reported (primarily to userspace); and update two comments to match changes in ACPI. Those make up most of this patch, by volume.

I've also made some pointer constant, as they are constant...

| | | | | | | | | | | | | | | | | | | | | | | | | | This patch addresses the following issues with the pxa2xx FIr driver: 1. increment overrun error counter and not frame error counter on ICSR1_ROR bit set in ICSR1. 2. drop frames reported with the frame error from the IC. 3. when resetting the receiver and preparing it for the next DMA in pxa_irda_fir_irq() actually clear the Rx FIFO. See description in Table 11-2 in PXA270 Developer's Manual of the RXE bit. Correction added in version 2: clearing the IC Rx FIFO also has to be done in pxa_irda_fir_dma_tx_irq() Signed-off-by: G.
