2014-10-03qdisc: bulk dequeue support for qdiscs with TCQ_F_ONETXQUEUEJesper Dangaard Brouer
Based on DaveM's recent API work on dev_hard_start_xmit(), that allows sending/processing an entire skb list. This patch implements qdisc bulk dequeue, by allowing multiple packets to be dequeued in dequeue_skb(). The optimization principle for this is two fold, (1) to amortize locking cost and (2) avoid expensive tailptr update for notifying HW. (1) Several packets are dequeued while holding the qdisc root_lock, amortizing locking cost over several packet. The dequeued SKB list is processed under the TXQ lock in dev_hard_start_xmit(), thus also amortizing the cost of the TXQ lock. (2) Further more, dev_hard_start_xmit() will utilize the skb->xmit_more API to delay HW tailptr update, which also reduces the cost per packet. One restriction of the new API is that every SKB must belong to the same TXQ. This patch takes the easy way out, by restricting bulk dequeue to qdisc's with the TCQ_F_ONETXQUEUE flag, that specifies the qdisc only have attached a single TXQ. Some detail about the flow; dev_hard_start_xmit() will process the skb list, and transmit packets individually towards the driver (see xmit_one()). In case the driver stops midway in the list, the remaining skb list is returned by dev_hard_start_xmit(). In sch_direct_xmit() this returned list is requeued by dev_requeue_skb(). To avoid overshooting the HW limits, which results in requeuing, the patch limits the amount of bytes dequeued, based on the drivers BQL limits. In-effect bulking will only happen for BQL enabled drivers. Small amounts for extra HoL blocking (2x MTU/0.24ms) were measured at 100Mbit/s, with bulking 8 packets, but the oscillating nature of the measurement indicate something, like sched latency might be causing this effect. More comparisons show, that this oscillation goes away occationally. Thus, we disregard this artifact completely and remove any "magic" bulking limit. For now, as a conservative approach, stop bulking when seeing TSO and segmented GSO packets. They already benefit from bulking on their own. A followup patch add this, to allow easier bisect-ability for finding regressions. Jointed work with Hannes, Daniel and Florian.

2014-10-03X.509: If available, use the raw subjKeyId to form the key descriptionDavid Howells
Module signing matches keys by comparing against the key description exactly. However, the way the key description gets constructed got changed to be composed of the subject name plus the certificate serial number instead of the subject name and the subjectKeyId. I changed this to avoid problems with certificates that don't *have* a subjectKeyId. Instead, if available, use the raw subjectKeyId to form the key description and only use the serial number if the subjectKeyId doesn't exist.

2014-10-03ASoC: tlv320aic3x: fix PLL D configurationDmitry Lavnikevich
Current caching implementation during regcache_sync() call bypasses all register writes of values that are already known as default (regmap reg_defaults). Same time in TLV320AIC3x codecs register 5 (AIC3X_PLL_PROGC_REG) write should be immediately followed by register 6 write (AIC3X_PLL_PROGD_REG) even if it was not changed. Otherwise both registers will not be written. This brings to issue that appears particulary in case of 44.1kHz playback with 19.2MHz master clock. In this case AIC3X_PLL_PROGC_REG is 0x6e while AIC3X_PLL_PROGD_REG is 0x0 (same as register default). Thus AIC3X_PLL_PROGC_REG also remains not written and we get wrong playback speed. In this patch snd_soc_read() is used to get cached pll values and snd_soc_write() (unlike regcache_sync() this function doesn't bypasses hardware default values) to write them to registers.

2014-10-03ASoC: dapm: Fix NULL pointer dereference when registering card with widgetsJarkko Nikula
Commit 0bd2ac3dae74 ("ASoC: Remove CODEC pointer from snd_soc_dapm_context") introduced regression to snd_soc_dapm_new_controls() when registering a card with card->dapm_widgets set. Call chain is: snd_soc_register_card() -> snd_soc_instantiate_card() -> snd_soc_dapm_new_controls() -> snd_soc_dapm_new_control() Null pointer dereference occurs since card->dapm context doesn't have associated component. Fix this by setting widget codec pointer conditionally.

2014-10-03PM / clk: Fix crash in clocks management code if !CONFIG_PM_RUNTIMEGeert Uytterhoeven
Unlike the clocks management code for runtime PM, the code used for system suspend does not check the pm_clock_entry.status field. If pm_clk_acquire() failed, ce->status will be PCE_STATUS_ERROR, and ce->clk will be a negative error code (e.g. 0xfffffffe = -2 = -ENOENT). Depending on the clock implementation, suspend or resume may crash with: Unable to handle kernel NULL pointer dereference at virtual address 00000026 (CCF clk_disable() has an IS_ERR_OR_NULL() check, while CCF clk_enable() only has a NULL check; pre-CCF implementations may behave differently) While just checking for PCE_STATUS_ERROR would be sufficient, it doesn't hurt to use the same state machine as is done for runtime PM, as this makes the two versions more similar, and eligible for a future consolidation.

2014-10-03mmc, sdhci, bcm-kona, LLVMLinux: Remove use of __initconstBehan Webster
The __initconst is in the wrong place, and when moved to the correct place it uncovers an error where the variable is used by non-init data structures. Instead merely make them const and put the const in the right spot.
