2014-01-10PCI: Removed unused parts of Page Request Interface supportStephen Hemminger
My philosophy is unused code is dead code. And dead code is subject to bit rot and is a likely source of bugs. Use it or lose it.

For the mac80211 bits, Johannes says: "Felix adds some helper functions for P2P NoA software tracking, Joe fixes alignment (but as this apparently never caused issues I didn't send it to 3.13), Kyeyoon/Jouni add QoS-mapping support (a Hotspot 2.0 feature), Weilong fixed a bunch of checkpatch errors and I get to play fire-fighter or so and clean up other people's locking issues. I also added nl80211 vendor-specific events, as we'd discussed at the wireless summit." For the iwlwifi bits, Emmanuel says: "I have here a rework of the interrupt handling to meet RT kernel requirements - basically we don't take any lock in the primary interrupt handler. This gave me a good reason to clean things up a bit on the way. There is also a fix of the QoS mapping along with a few workarounds for hardware / firmware issues that are hard to hit. Three fixes suggested by static analyzers, and other various stuff. Most importantly, I update the Copyright note to include the new year." For the bluetooth bits, Gustavo says: "More patches to 3.14. The bulk of changes here is the 6LoWPAN support for Bluetooth LE Devices. The commits that touches net/ieee802154/ are already acked by David Miller. Other than that we have some RFCOMM fixes and improvements plus fixes and clean ups all over the tree." Beyond that, ath9k, brcmfmac, mwifiex, and wil6210 get their usual level of attention.

2014-01-10net: core: explicitly select a txq before doing l2 forwardingJason Wang
Currently, the tx queue were selected implicitly in ndo_dfwd_start_xmit(). The will cause several issues: - NETIF_F_LLTX were removed for macvlan, so txq lock were done for macvlan instead of lower device which misses the necessary txq synchronization for lower device such as txq stopping or frozen required by dev watchdog or control path. - dev_hard_start_xmit() was called with NULL txq which bypasses the net device watchdog. - dev_hard_start_xmit() does not check txq everywhere which will lead a crash when tso is disabled for lower device. Fix this by explicitly introducing a new param for .ndo_select_queue() for just selecting queues in the case of l2 forwarding offload. netdev_pick_tx() was also extended to accept this parameter and dev_queue_xmit_accel() was used to do l2 forwarding transmission. With this fixes, NETIF_F_LLTX could be preserved for macvlan and there's no need to check txq against NULL in dev_hard_start_xmit(). Also there's no need to keep a dedicated ndo_dfwd_start_xmit() and we can just reuse the code of dev_queue_xmit() to do the transmission. In the future, it was also required for macvtap l2 forwarding support since it provides a necessary synchronization method.

2014-01-10arm64: kernel: restore HW breakpoint registers in cpu_suspendLorenzo Pieralisi
When a CPU resumes from low-power, it restores HW breakpoint and watchpoint slots through a CPU PM notifier. Since we want to enable debugging as early as possible in the resume path, the mdscr content is restored along the general purpose registers in the cpu_suspend API and debug exceptions are reenabled when cpu_suspend returns. Since the CPU PM notifier is run after a CPU has been resumed, we cannot expect HW breakpoint registers to contain sane values till the notifier is run, since the HW breakpoints registers content is unknown at reset; this means that the CPU might run with debug exceptions enabled, mdscr restored but HW breakpoint registers containing junk values that can trigger spurious debug exceptions. This patch fixes current HW breakpoints restore by moving the HW breakpoints registers restoration to the cpu_suspend API, before the debug exceptions are enabled. This way, as soon as the cpu_suspend function returns the kernel can resume debugging with sane values in HW breakpoint registers.

Per the SR-IOV spec rev 1.1: 3.4.1.9 Header Type (Offset 0Eh) "... For VFs, this register must be RO Zero." Unfortunately some devices get this wrong, ex. Emulex OneConnect 10Gb NIC. When they do it makes us handle ACS testing and therefore IOMMU groups as if they were actual multifunction devices and require ACS capabilities to make sure there's no peer-to-peer between functions. VFs are never traditional multifunction devices, so simply clear this bit before we get any further into setup.

2014-01-10dm cache: add block sizes and total cache blocks to status outputMike Snitzer
Improve cache_status to emit: <metadata block size> <#used metadata blocks>/<#total metadata blocks> <cache block size> <#used cache blocks>/<#total cache blocks> ... Adding the block sizes allows for easier calculation of the overall size of both the metadata and cache devices. Adding <#total cache blocks> provides useful context for how much of the cache is used. Unfortunately these additions to the status will require updates to users' scripts that monitor the cache status. But these changes help provide more comprehensive information about the cache device and will simplify tools that are being developed to manage dm-cache devices -- because they won't need to issue 3 operations to cobble together the information that we can easily provide via a single status ioctl. While updating the status documentation in cache.txt spaces were tabify'd.

2014-01-10ASoC: fsl_esai: Add ESAI CPU DAI driverNicolin Chen
This patch implements a device-tree-only CPU DAI driver for Freescale ESAI controller that supports: - 12 channels playback and 8 channels record. [ Some of the inner transmitters and receivers are sharing same group of pins. So the maxmium 12 output or 8 input channels are only valid if there is no pin conflict occurring to it. ] - Independent (asynchronous mode) or shared (synchronous mode) transmit and receive sections with separate or shared internal/external clocks and frame syncs, operating in Master or Slave mode. [ Current ALSA seems not to allow CPU DAI drivers to configure DAI format separately for PLAYBACK and CAPTURE. So this first version only supports the case that uses the same DAI format for both directions. ] - Various DAI formats: I2S, Left-Justified, Right-Justified, DSP-A and DSP-B. - Programmable word length (8, 16, 20 or 24bits) - Flexible selection between system clock or external oscillator as input clock source, programmable internal clock divider and frame sync generation.

2014-01-10ath10k: add set_bitrate_mask callbackJanusz Dziedzic
Add set_bitrate_mask callback. Currently ath10k HW is limited to handle only single fixed rate setting or limit number of used spatial streams. Example: iw wlanX set bitrates legacy-5 ht-mcs-5 vht-mcs-5 2:9 will setup VHT, nss=2, mcs=9 iw wlanX set bitrates legacy-5 18 ht-mcs-5 vht-mcs-5 will setup legacy, 18Mbps iw wlanX set bitrates legacy-5 ht-mcs-5 3 vht-mcs-5 will setup HT, nss=1, mcs=3 iw wlanX set bitrate legacy-5 ht-mcs-5 vht-mcs-5 1:0-9 will setup nss=1 iw wlanX set bitrate legacy-5 ht-mcs-5 vht-mcs-5 1:0-9 2:0-9 will setup nss=2 Signed-off-by: Janusz Dziedzic <janusz.dziedzic@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2014-01-10ath10k: add debugfs file to control firmware dbglogKalle Valo
Firmware dbglogs can be now enabled through fw_dbglog file. To enable all possible log messages run: echo 0xffffffff > /sys/kernel/debug/ieee80211/phy0/ath10k/fw_dbglog And to put back firmare defaults use 0x0: echo 0x0 > /sys/kernel/debug/ieee80211/phy0/ath10k/fw_dbglog Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2014-01-10ath10k: add trace event for WMI_DEBUG_MESG_EVENTIDKalle Valo
Send firmware WMI debug logs to user space for further processing. Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2014-01-10ath10k: handle WMI debug print eventsKalle Valo
Firmware can send simple ascii strings as debug messages using WMI_DEBUG_PRINT_EVENTID, print those with ATH10K_DBG_WMI log level. Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2014-01-10ath10k: track number of existing peersBartosz Markowski
To not exceed number of allowed clients (AP mode), make sure to check how many of them are already on the peers list. 10.X firmware support up to 127 peers, non-AP centric firmwares 16. Signed-off-by: Bartosz Markowski <bartosz.markowski@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2014-01-10ath10k: disable STA kickout in FWMarek Puzyniak
Currently ath10k is not using STA KICKOUT firmware functionality. In order to avoid unwanted WMI_PEER_STA_KICKOUT_EVENT event this functionality should be disabled when not used. Signed-off-by: Marek Puzyniak <marek.puzyniak@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
