2015-02-27mwifiex: more_task flag for main_processShengzhen Li
This patch handles a corner case where TX packet would remain in driver queue till next packet comes in. Here is sequence: 1. TX packet is queued via hard_start_xmit and main_work is queued 2. SDIO interrupt comes in which directly call mwifiex_main_process. This starts executing main superloop. 3. Now work from step1 is scheduled but at first check itself it sees mwifiex_processing is set and exits. 4. Now if superloop from step2 has passed TX processing part of superloop this packet would remain in queue until next packet/command/SDIO interrupt arrives and queues main_work. This patch fixes this corner case by defining more_task flag which is set when mwifiex_processing is found to be true. At end of superloop we again check if more_task flag is set and if set, execute superloop again.

2015-02-26mac80211: Send EAPOL frames at lowest rateJouni Malinen
The current minstrel_ht rate control behavior is somewhat optimistic in trying to find optimum TX rate. While this is usually fine for normal Data frames, there are cases where a more conservative set of retry parameters would be beneficial to make the connection more robust. EAPOL frames are critical to the authentication and especially the EAPOL-Key message 4/4 (the last message in the 4-way handshake) is important to get through to the AP. If that message is lost, the only recovery mechanism in many cases is to reassociate with the AP and start from scratch. This can often be avoided by trying to send the frame with more conservative rate and/or with more link layer retries. In most cases, minstrel_ht is currently using the initial EAPOL-Key frames for probing higher rates and this results in only five link layer transmission attempts (one at high(ish) MCS and four at MCS0). While this works with most APs, it looks like there are some deployed APs that may have issues with the EAPOL frames using HT MCS immediately after association. Similarly, there may be issues in cases where the signal strength or radio environment is not good enough to be able to get frames through even at couple of MCS 0 tries. The best approach for this would likely to be to reduce the TX rate for the last rate (3rd rate parameter in the set) to a low basic rate (say, 6 Mbps on 5 GHz and 2 or 5.5 Mbps on 2.4 GHz), but doing that cleanly requires some more effort. For now, we can start with a simple one-liner that forces the minimum rate to be used for EAPOL frames similarly how the TX rate is selected for the IEEE 802.11 Management frames. This does result in a small extra latency added to the cases where the AP would be able to receive the higher rate, but taken into account how small number of EAPOL frames are used, this is likely to be insignificant. A future optimization in the minstrel_ht design can also allow this patch to be reverted to get back to the more optimized initial TX rate. It should also be noted that many drivers that do not use minstrel as the rate control algorithm are already doing similar workarounds by forcing the lowest TX rate to be used for EAPOL frames.

2015-02-26arm64: Fix text patching logic when using fixmapMarc Zyngier
Patch 2f896d586610 ("arm64: use fixmap for text patching") changed the way we patch the kernel text, using a fixmap when the kernel or modules are flagged as read only.

This patch increases the interleave factor for parallel AES modes to 4x. This improves performance on Cortex-A57 by ~35%. This is due to the 3-cycle latency of AES instructions on the A57's relatively deep pipeline (compared to Cortex-A53 where the AES instruction latency is only 2 cycles). At the same time, disable inline expansion of the core AES functions, as the performance benefit of this feature is negligible.

2015-02-26bridge: fix link notification skb size calculation to include vlan rangesRoopa Prabhu
my previous patch skipped vlan range optimizations during skb size calculations for simplicity. This incremental patch considers vlan ranges during skb size calculations. This leads to a bit of code duplication in the fill and size calculation functions. But, I could not find a prettier way to do this. will take any suggestions. Previously, I had reused the existing br_get_link_af_size size calculation function to calculate skb size for notifications. Reusing it this time around creates some change in behaviour issues for the usual .get_link_af_size callback.

2015-02-26ARM: multi_v7_defconfig: Enable shmobile platformsGeert Uytterhoeven
Enable support for shmobile platforms that became multi-platform aware. Several non-critical drivers and subsystems are built as modules, to keep kernel size reasonable. Tested on: - r8a73a4/ape6evm: - U-Boot fails with "Error: unrecognized/unsupported machine ID", - kexec works. - r8a7740/armadillo: - Hermit boot loader fails (larger image, more memory corruption), - kexec works. - r8a7791/koelsch, - sh73a0/kzm9g: - zImage+DTB from U-Boot needs CONFIG_ARM_ATAG_DTB_COMPAT=n, - kexec works. - am335x/boneblack.

2015-02-26ath9k_htc: Add new USB IDLeon Nardella
This device is a dongle made by Philips to enhance their TVs with wireless capabilities, but works flawlessly on any upstream kernel, provided that the ath9k_htc module is attached to it. It's correctly recognized by lsusb as "0471:209e Philips (or NXP) PTA01 Wireless Adapter" and the patch has been tested on real hardware.
