2014-01-08mfd: twl-core: Simplify IO wrapper functions by moving common code outPeter Ujfalusi
The new twl_get_regmap() function will return a pointer to the regmap needed for the given module. Since both read and write function were using the same code to do the lookup we can reuse this in both places to simplify the code.

2014-01-08GFS2: For exhash conversion, only one block is neededSteven Whitehouse
For most cases, only a single new block is needed when we reach the point of converting from stuffed to exhash directory. The exception being when the file name is so long that it will not fit within the new leaf block. So this patch adds a simple test for that situation so that we do not need to request the full reservation size in this case. Potentially we could calculate more accurately the value to use in other cases too, but that is much more complicated to do and it is doubtful that the benefit would outweigh the extra cost in code complexity.

2014-01-08ALSA: hda - Don't create duplicated ctls for loopback pathsTakashi Iwai
AD1986A mic pins (0x1d and 0x1f) share the same widget for controlling the loopback volume/mute, but the generic parser didn't check it. This ended up with the duplicated controls for the same effect. This patch adds the check of the duplication for avoiding it. After this fix, there will be only one control although it affects both paths; this remaining issue should be fixed later in a different patch.

2014-01-08ALSA: hda - Increment default stream numbers for AMD HDMI controllersTakashi Iwai
It turned out that some AMD HDMI controllers still don't provide proper values in GCAP register (all zero), and the driver assigns only one stream in that case, although the connected codec chip supports more than one stream. In this patch, the default max number of streams for AMD HDMI controllers is increased to 8, which should suffice for most use cases. The overhead by this increase is more azx_dev struct and BDL allocations, so it's negligible. Of course, if the controller provides a proper GCAP register, the register value would be used.

2014-01-07dm: wait until embedded kobject is released before destroying a deviceMikulas Patocka
There may be other parts of the kernel holding a reference on the dm kobject. We must wait until all references are dropped before deallocating the mapped_device structure. The dm_kobject_release method signals that all references are dropped via completion. But dm_kobject_release doesn't free the kobject (which is embedded in the mapped_device structure). This is the sequence of operations: * when destroying a DM device, call kobject_put from dm_sysfs_exit * wait until all users stop using the kobject, when it happens the release method is called * the release method signals the completion and should return without delay * the dm device removal code that waits on the completion continues * the dm device removal code drops the dm_mod reference the device had * the dm device removal code frees the mapped_device structure that contains the kobject Using kobject this way should avoid the module unload race that was mentioned at the beginning of this thread: https://lkml.org/lkml/2014/1/4/83 Signed-off-by: Mikulas Patocka <mpatocka@redhat.com> Signed-off-by: Mike Snitzer <snitzer@redhat.com> Cc: stable@vger.kernel.org

2014-01-07serial: 8250: enable UART_BUG_NOMSR for TegraStephen Warren
Tegra chips have 4 or 5 identical UART modules embedded. UARTs C..E have their MODEM-control signals tied off to a static state. However UARTs A and B can optionally route those signals to/from package pins, depending on the exact pinmux configuration. When these signals are not routed to package pins, false interrupts may trigger either temporarily, or permanently, all while not showing up in the IIR; it will read as NO_INT. This will eventually lead to the UART IRQ being disabled due to unhandled interrupts. When this happens, the kernel may print e.g.: irq 68: nobody cared (try booting with the "irqpoll" option) In order to prevent this, enable UART_BUG_NOMSR. This prevents UART_IER_MSI from being enabled, which prevents the false interrupts from triggering. In practice, this is not needed under any of the following conditions: * On Tegra chips after Tegra30, since the HW bug has apparently been fixed. * On UARTs C..E since their MODEM control signals are tied to the correct static state which doesn't trigger the issue. * On UARTs A..B if the MODEM control signals are routed out to package pins, since they will then carry valid signals. However, we ignore these exceptions for now, since they are only relevant if a board actually hooks up more than a 4-wire UART, and no currently supported board does this. If we ever support a board that does, we can refine the algorithm that enables UART_BUG_NOMSR to take those exceptions into account, and/or read a flag from DT/... that indicates that the board has hooked up and pinmux'd more than a 4-wire UART.

2014-01-07tty/serial: at91: reset rx_ring when port is shutdownMark Deneen
When using RX DMA, the driver won't pass any data to the uart layer until the buffer is flipped. When the port is shutdown, the dma buffers are unmapped, but the head and tail of the ring buffer are not reseted. Since the serial console will keep the port open, this will only present itself when the uart is not shared. To reproduce the issue, with an unpatched driver, run a getty on /dev/ttyS0 with no serial console and exit. Getty will exit, and when the new one returns you will be unable to log in. If you hold down a key long enough to fill the DMA buffer and flip it, you can then log in.

The four variants of the synclink driver use the same code in their open() callback to wait for a port in process of being closed, using interruptible_sleep_on, which is racy and going away soon. Making things worse, these functions hold the BTM while doing so, which means that if we ever enter this code path, we cannot actually continue since the other thread that is in process of closing the port can no longer get the BTM. This addresses both issues by using wait_event_interruptible_tty() instead.
