2014-01-29ALSA: oxygen: Xonar DG(X): cleanup and minor changesRoman Volkov
Remove old SPI control functions, change anti-pop init sequence, remove some garbage from structures. The 'Apply' functions must be called at the mixer initialization, otherwise mixer settings sometimes will not be applied at startup. Signed-off-by: Roman Volkov <v1ron@mail.ru> Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2014-01-29ALSA: oxygen: Xonar DG(X): modify high-pass filter controlRoman Volkov
Change the 'put' function of the high-pass filter control to use the new SPI functions. Signed-off-by: Roman Volkov <v1ron@mail.ru> Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2014-01-29ALSA: oxygen: Xonar DG(X): modify input select functionsRoman Volkov
First of all, we should not touch the GPIOs. They are not for selecting the capture source, but they seems just enable the whole audio input curcuit. The 'put' function calls the 'apply' functions to change register values. Change the order of capture sources.

2014-01-29ALSA: oxygen: Xonar DG(X): modify capture volume functionsRoman Volkov
Modify the input_vol_* functions to use the new SPI routines, There is a new applying function that will be called when the capture source changed. Signed-off-by: Roman Volkov <v1ron@mail.ru> Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2014-01-29ALSA: oxygen: Xonar DG(X): use headphone volume controlRoman Volkov
I tried both variants: volume control and impedance selector. In the first case one minus is that we can't change the volume of multichannel output without additional software volume control. However, I am using this variant for the last three months and this seems good. All multichannel speaker systems have internal amplifier with the volume control included, but not all headphones have this regulator. In the second case, my software volume control does not save the value after reboot. Signed-off-by: Roman Volkov <v1ron@mail.ru> Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2014-01-29ALSA: oxygen: Xonar DG(X): modify playback output selectRoman Volkov
Change the order of elements in the output select control. This will reduce the number of relay switches. Change 'put' function to call the oxygen_update_dac_routing() function. Otherwise multichannel playback does not work. Also there is a new function to apply settings, this prevents from duplicating the code.

2014-01-29ALSA: oxygen: Xonar DG(X): capture from I2S channel 1, not 2Roman Volkov
Actually CS4245 connected to the I2S channel 1 for capture, not channel 2. Otherwise capturing and playback does not work for CS4245. Signed-off-by: Roman Volkov <v1ron@mail.ru> Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2014-01-29ALSA: oxygen: Xonar DG(X): move the mixer code into another fileRoman Volkov
Moving the mixer code away makes things easier. The mixer will control the driver, so the functions of the driver need to be non-static. Signed-off-by: Roman Volkov <v1ron@mail.ru> Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2014-01-29ALSA: oxygen: modify CS4245 register dumping functionRoman Volkov

2014-01-29ALSA: oxygen: modify adjust_dg_dac_routing functionRoman Volkov
When selecting the audio output destinations (headphones, FP headphones, multichannel output), the channel routing should be changed depending on what destination selected. Also unnecessary I2S channels are digitally muted. This function called when the user selects the destination in the ALSA mixer. Signed-off-by: Roman Volkov <v1ron@mail.ru> Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2014-01-29ALSA: oxygen: Xonar DG(X): modify DAC/ADC parameters functionRoman Volkov
When selecting the audio sample rate for CS4245, the MCLK divider should also be changed. Signed-off-by: Roman Volkov <v1ron@mail.ru> Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2014-01-29ALSA: oxygen: Xonar DG(X): modify initialization functionsRoman Volkov
Change CS4245 initialization: different sequence and GPIO values, according to datasheets and reverse-engineering information. Change cleanup/resume/suspend functions, since they use initialization. Signed-off-by: Roman Volkov <v1ron@mail.ru> Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2014-01-29ALSA: oxygen: Xonar DG(X): add new CS4245 SPI functionsRoman Volkov
Add the new SPI write and read functions. The SPI read function is used for creating initial registers dump and may be used for debugging purposes. SPI operations are cached, so there is a new function to manage the cache (shadow). I have to remove the shift from the CS4245_SPI_* constants, since when we are performing the reading, we need to shift by 8 instead of 16.

2014-01-29ALSA: oxygen: additional definitions for the Xonar DG/DGX cardRoman Volkov
Add additional constants to the xonar_dg.h file: capture and playback sources. Move GPIO_* constants and the dg struct to the header file from the xonar_dg.c file. Signed-off-by: Roman Volkov <v1ron@mail.ru> Signed-off-by: Clemens Ladisch <clemens@ladisch.de>

2014-01-29ALSA: oxygen: export oxygen_update_dac_routing symbolRoman Volkov
When the user switches the output from stereo to multichannel or vice versa, the driver needs to update the channel routing. Instead of creating additional subroutines, I better export existing oxygen_update_dac_routing symbol from the oxygen mixer and call this function. It calls model.adjust_dac_routing() and my function does the work. Signed-off-by: Roman Volkov <v1ron@mail.ru> Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2014-01-29ALSA: oxygen: add mute mask for the OXYGEN_PLAY_ROUTING registerRoman Volkov
The Xonar DG/DGX driver needs this mask to mute unnecessary channels. Signed-off-by: Roman Volkov <v1ron@mail.ru> Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2014-01-29ALSA: oxygen: modify the SPI writing functionRoman Volkov
Modify the oxygen_write_spi() function to use the newly introduced oxygen_wait_spi() function. Change return value from void to int, so it can return error codes. Older drivers just ignore that return value, new drivers can check this value. We need to wait AFTER initiating the SPI transaction, otherwise read operation will not work. Signed-off-by: Roman Volkov <v1ron@mail.ru> Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2014-01-29ALSA: oxygen: add the separate SPI waiting functionRoman Volkov
The oxygen_wait_spi() function now performs waiting when the SPI bus completes a transaction. Introduce the timeout error checking and increase timeout to 200 from 40. Signed-off-by: Roman Volkov <v1ron@mail.ru> Signed-off-by: Clemens Ladisch <clemens@ladisch.de>

Pull networking fixes from David Miller: 1) The value choosen for the new SO_MAX_PACING_RATE socket option on parisc was very poorly choosen, let's fix it while we still can. From Eric Dumazet. 2) Our generic reciprocal divide was found to handle some edge cases incorrectly, part of this is encoded into the BPF as deep as the JIT engines themselves. Just use a real divide throughout for now. From Eric Dumazet. 3) Because the initial lookup is lockless, the TCP metrics engine can end up creating two entries for the same lookup key. Fix this by doing a second lookup under the lock before we actually create the new entry. From Christoph Paasch. 4) Fix scatter-gather list init in usbnet driver, from Bjørn Mork. 5) Fix unintended 32-bit truncation in cxgb4 driver's bit shifting.

2014-01-17s390/bpf,jit: fix 32 bit divisions, use unsigned divide instructionsHeiko Carstens
The s390 bpf jit compiler emits the signed divide instructions "dr" and "d" for unsigned divisions. This can cause problems: the dividend will be zero extended to a 64 bit value and the divisor is the 32 bit signed value as specified A or X accumulator, even though A and X are supposed to be treated as unsigned values. The divide instrunctions will generate an exception if the result cannot be expressed with a 32 bit signed value. This is the case if e.g. the dividend is 0xffffffff and the divisor either 1 or also 0xffffffff (signed: -1). To avoid all these issues simply use unsigned divide instructions.

2014-01-17ipv6: simplify detection of first operational link-local address on interfaceHannes Frederic Sowa
In commit 1ec047eb4751e3 ("ipv6: introduce per-interface counter for dad-completed ipv6 addresses") I build the detection of the first operational link-local address much to complex. Additionally this code now has a race condition. Replace it with a much simpler variant, which just scans the address list when duplicate address detection completes, to check if this is the first valid link local address and send RS and MLD reports then.

2014-01-17tcp: metrics: Avoid duplicate entries with the same destination-IPChristoph Paasch
Because the tcp-metrics is an RCU-list, it may be that two soft-interrupts are inside __tcp_get_metrics() for the same destination-IP at the same time. If this destination-IP is not yet part of the tcp-metrics, both soft-interrupts will end up in tcpm_new and create a new entry for this IP. So, we will have two tcp-metrics with the same destination-IP in the list. This patch checks twice __tcp_get_metrics(). First without holding the lock, then while holding the lock. The second one is there to confirm that the entry has not been added by another soft-irq while waiting for the spin-lock. Fixes: 51c5d0c4b169b (tcp: Maintain dynamic metrics in local cache.)

commit ae4b46e9d "net: rds: use this_cpu_* per-cpu helper" broke per-cpu handling for rds. chpfirst is the result of __this_cpu_read(), so it is an absolute pointer and not __percpu. Therefore, __this_cpu_write() should not operate on chpfirst, but rather on cache->percpu->first, just like __this_cpu_read() did before.

2014-01-16perf/x86/amd/ibs: Fix waking up from S3 for AMD family 10hRobert Richter
On AMD family 10h we see following error messages while waking up from S3 for all non-boot CPUs leading to a failed IBS initialization: Enabling non-boot CPUs ... smpboot: Booting Node 0 Processor 1 APIC 0x1 [Firmware Bug]: cpu 1, try to use APIC500 (LVT offset 0) for vector 0x400, but the register is already in use for vector 0xf9 on another cpu perf: IBS APIC setup failed on cpu #1 process: Switch to broadcast mode on CPU1 CPU1 is up ... ACPI: Waking up from system sleep state S3 Reason for this is that during suspend the LVT offset for the IBS vector gets lost and needs to be reinialized while resuming. The offset is read from the IBSCTL msr. On family 10h the offset needs to be 1 as offset 0 is used for the MCE threshold interrupt, but firmware assings it for IBS to 0 too. The kernel needs to reprogram the vector. The msr is a readonly node msr, but a new value can be written via pci config space access. The reinitialization is implemented for family 10h in setup_ibs_ctl() which is forced during IBS setup. This patch fixes IBS setup after waking up from S3 by adding resume/supend hooks for the boot cpu which does the offset reinitialization. Marking it as stable to let distros pick up this fix.

(off by one in some cases) http://www.wireshark.org/~darkjames/reciprocal-buggy.c He could also show this with BPF: http://www.wireshark.org/~darkjames/set-and-dump-filter-k-bug.c The reciprocal divide in linux kernel is not generic enough, lets remove its use in BPF, as it is not worth the pain with current cpus.

2014-01-15bnx2x: Don't release PCI bars on shutdownYuval Mintz
The bnx2x driver in its pci shutdown() callback releases its pci bars (in the same manner it does during its pci remove() callback). During a system reboot while VFs are enabled, its possible for the VF's remove to be called (as a result of pci_disable_sriov()) after its shutdown callback has already finished running; This will cause a paging request fault as the VF tries to access the pci bar which it has previously released, crashing the system. This patch further differentiates the shutdown and remove callbacks, preventing the pci release procedures from being called during shutdown.

2014-01-15batman-adv: fix batman-adv header overhead calculationMarek Lindner
Batman-adv prepends a full ethernet header in addition to its own header. This has to be reflected in the MTU calculation, especially since the value is used to set dev->hard_header_len. Introduced by 411d6ed93a5d0601980d3e5ce75de07c98e3a7de ("batman-adv: consider network coding overhead when calculating required mtu") Reported-by: cmsv <cmsv@wirelesspt.net> Reported-by: Martin Hundebøll <martin@hundeboll.net> Signed-off-by: Marek Lindner <mareklindner@neomailbox.ch> Signed-off-by: Antonio Quartulli <antonio@meshcoding.com>
