Add support for raw VBI capture for the em28xx bridge, currently only for NTSC. Support for PAL capture to follow shortly (including the removal of numerous hard-coded NTSC-specific sizes for capture buffers, etc). Note that the code currently changes the default current norm from PAL to NTSC (so that zvbi-ntsc-cc works properly). The default norm really should be moved into a board-level parameter.

Add code enabling the VBI registers for variants of the em28xx chip that support VBI, and make sure the isoc streaming code continues to work for the video component of the stream (note the video and vbi data arrive intermixed on the same isoc pipe). Note that this version just drops the actual VBI data onto the floor as opposed to processing it. The "#ifdef 0" tags are for the videobuf code that appears in the next patch in this series. We created a separate version of the isoc_copy version for parsing the version of the stream that includes VBI data. In theory, they might be able to be merged at some point in the future, but the initial goal is to ensure that we do not cause any regressions with devices that do not have VBI support.

Commit ac89a917 ("pty: don't limit the writes to 'pty_space()' inside 'pty_write()'") removed the pty_space() checking, in order to let the regular tty buffer code limit the buffering itself. That was all good, but as a subtle side effect it meant that we'd be doing a tty_wakeup() even in the case where the buffers were all filled up, and didn't actually make any progress on the write. Which sounds innocuous, but it interacts very badly with the ppp_async code, which has an infinite loop in ppp_async_push() that tries to push out data to the tty. When we call tty_wakeup(), that loop ends up thinking that progress was made (see the subtle interactions between XMIT_WAKEUP and 'tty_stuffed' for details). End result: one unhappy ppp user. Fixed by noticing when tty_insert_flip_string() didn't actually do anything, and then not doing any more processing (including, very much not calling tty_wakeup()).

The WDIOC_SETTIMEOUT argument is supposed to be a "seconds" value. However, the book E wdt currently treats it as a "period" which is interpreted in a board-specific way. This patch allows the user to pass in a "seconds" value and the driver will set the smallest timeout that is at least as large as specified by the user. It's been tested on e500 hardware and works as expected. The patch only modifies the CONFIG_FSL_BOOKE case, the CONFIG_4xx case is left unmodified as I don't have any hardware to test it on.

On a Compaq Presario V3000 laptop (NVIDIA MCP51 chipset), pata_amd selects PIO0 mode for the PATA DVD-RAM drive instead of MWDMA2 which it supports: ata4.00: ATAPI: HL-DT-ST DVDRAM GSA-4084N, KQ09, max MWDMA2 ata4: nv_mode_filter: 0x39f&0x7001->0x1, BIOS=0x0 (0x0) ACPI=0x7001 (60:600:0x11) ata4.00: configured for PIO0 For some reason, the BIOS-set UDMA configuration returns 0 and the ACPI _GTM reports that UDMA2 and PIO0 are enabled. This causes nv_mode_filter to end up allowing only PIO0 and UDMA0-2. Since the drive doesn't support UDMA we end up using PIO0. Since the controllers should always support PIO4, MWDMA2 and UDMA2 regardless of what cable type is used, let's make sure we don't filter out these modes regardless of what wacky settings the BIOS is using.

sata_promise's reset code has deviated quite a bit from the Promise reference driver's, and it has been observed to fail to recover from errors in some cases. This patch thus updates the reset code to more closely match the reference driver: - soft reset (pdc_reset_port): * wait for ATA engine to not be in packet command mode (2nd gen only) * write reset bit in PDC_CTLSTAT before the first read in the loop * for 2nd gen SATA follow up with FPDMA reset and clearing error status registers - hard reset (pdc_sata_hardreset): * wait for ATA engine to not be in packet command mode (2nd gen only) * reset ATA engine via the PCI control register * Tejun's change to use non-waiting hardreset + follow-up SRST I'm not changing the hotplug mask bits since they are taken care of by sata_promise's ->freeze() and ->thaw() operations. And I'm not writing the PMP port # because that's always zero (for now). Tested here on various controllers. In particular, one disk which used to timeout and fail to recover from certain hdparm and smartmonctl commands now works nicely.

1st generation Promise SATA chips are prone to generating spurious hotplug events which can disrupt normal operation. This has been observed on 20376 and 20378 chips. This patch thus disables hotplug support on 1st gen chips while leaving it enabled for 2nd gen chips. The pdc_sata_hotplug_offset() function becomes redundant so it is removed. Tested on 1st gen 20376 and 20378 mainboard chips and on a 2nd gen SATA300 PCI card.

Commit 54c38444 makes libata abort qcs after the port is frozen. This is necessary to guarantee that TF registers are accessed after the DMA engine is shutdown after an error. However, this triggers WARN_ON_ONCE() check in ata_qc_complete() spuriously. Move WARN_ON_ONCE() downwards such that failing commands while frozen doesn't trigger it.

Commit a5bfc471 dropped explicit pci_intx() manipulation from ahci because it seemed unnecessary and ahci doesn't seem to be the right place to be tweaking it if it were. This was largely okay but there are exceptions. There was one on an embedded platform which was fixed via firmware and now bko#14124 reports it on a HP DL320. http://bugzilla.kernel.org/show_bug.cgi?id=14124 I still think this isn't something libata drivers should be caring about (the only ones which are calling pci_intx() explicitly are libata ones and one other driver) but for now reverting the change seems to be the right thing to do.

If we reach the test just below the loop with a `timeout' value of 0, this does not mean that the timeout caused the loop to end, but rather the `smi_rd.s.pending', in the last iteration. If timeout caused the loop to end, then `timeout' is -1, not 0. Since this can occur only in the last iteration, it is not very likely to be a problem. By changing the post- to prefix decrement we ensure that a timeout of 0 does mean it timed out.
