2017-04-19iwlwifi: mvm: support new TX APISara Sharon
Support the new TX command API for a000 devices. Command is a very slim version of current TX command. Generalize iwl_mvm_tx_mpdu to get rid of TX command dependencies. Signed-off-by: Sara Sharon <sara.sharon@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2017-04-19iwlwifi: mvm: add support for EWRD (Dynamic SAR) ACPI tableLuca Coelho
Dynamic SAR allows changing TX power limits at runtime to comply with SAR regulations on multiple form factors (e.g. tablet vs. clamshell mode). To support this, a new table was added to ACPI, which is called Extended Wireless Regulatory Descriptor (EWRD). This table allows OEMs to define different TX power profiles for each form-factor or usage mode. Read this new table and store it in our SAR profiles table, in preparation for Dynamic SAR support. Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2017-04-19iwlwifi: mvm: spin off SAR profile selection functionLuca Coelho
For dynamic SAR, we will need to select the current profile from different places. In preparation for that, spin the profile selection code out of iwl_mvm_sar_init(). Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2017-04-19iwlwifi: mvm: refactor SAR init to prepare for dynamic SARHaim Dreyfuss
We are adding support for dynamic TX power tables for SAR (specific absorption rate) compliance. Currently, we only support a single (static) TX power table, which is read from ACPI, and use it statically. To prepare for more tables that can be switched dynamically, refactor the SAR init flow to allow reusage and add the current static table as a single entry in an array of tables.

2017-04-19iwlwifi: mvm: prepare for station count changeSara Sharon
In a000 devices we will support up to 32 stations. The max station define is used also for invalid station marking which makes finding usages of actual maximum station pretty hard to sort through - change it to be a different define in order to make future changes easier. Use also ARRAY_SIZE intead of define when possible. Do not move yet to 32 stations until firmware do it though.

2017-04-19iwlwifi: mvm: add queues after adding stationSara Sharon
Currently aux & broadcast queues are added before calling add station, which results with a SCD_QUEUE_CFG command sent with a station id unknown yet to fw. While this works for pre-a000 firmware, the a000 fw requires the order to be reversed. The reason the change is only for a000 devices and not for previous devices is that we cannot reverse the order since the tfd_queue_mask containing the aux queue will cause FW to assert on adding a queue mask with a queue that is not enabled. This is not a problem in a000 fw since the tfd_queue_mask was removed from the add sta API. Signed-off-by: Sara Sharon <sara.sharon@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>

2017-04-19backlight: pwm_bl: Fix GPIO out for unimplemented .get_direction()Geert Uytterhoeven
Commit 7613c922315e308a ("backlight: pwm_bl: Move the checks for initial power state to a separate function") not just moved some code, but made slight changes in semantics. If a gpiochip doesn't implement the optional .get_direction() callback, gpiod_get_direction always returns -EINVAL, which is never equal to GPIOF_DIR_IN, leading to the GPIO not being configured for output. To avoid this, invert the test and check for not GPIOF_DIR_OUT instead, like the original code did. This restores the display on r8a7740/armadillo.

2017-04-19tracing: Allocate the snapshot buffer before enabling probeSteven Rostedt (VMware)
Currently the snapshot trigger enables the probe and then allocates the snapshot. If the probe triggers before the allocation, it could cause the snapshot to fail and turn tracing off. It's best to allocate the snapshot buffer first, and then enable the trigger. If something goes wrong in the enabling of the trigger, the snapshot buffer is still allocated, but it can also be freed by the user by writting zero into the snapshot buffer file. Also add a check of the return status of alloc_snapshot().

2017-04-19lightnvm: assume 64-bit lba numbersArnd Bergmann
The driver uses both u64 and sector_t to refer to offsets, and assigns between the two.

2017-04-19acpi/arm64: Add memory-mapped timer support in GTDT driverFu Wei
On platforms booting with ACPI, architected memory-mapped timers' configuration data is provided by firmware through the ACPI GTDT static table. The clocksource architected timer kernel driver requires a firmware interface to collect timer configuration and configure its driver. this infrastructure is present for device tree systems, but it is missing on systems booting with ACPI. Implement the kernel infrastructure required to parse the static ACPI GTDT table so that the architected timer clocksource driver can make use of it on systems booting with ACPI, therefore enabling the corresponding timers configuration.

2017-04-19netfilter: tcp: Use TCP_MAX_WSCALE instead of literal 14Gao Feng
The window scale may be enlarged from 14 to 15 according to the itef draft https://tools.ietf.org/html/draft-nishida-tcpm-maxwin-03. Use the macro TCP_MAX_WSCALE to support it easily with TCP stack in the future. Signed-off-by: Gao Feng <fgao@ikuai8.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2017-04-19netfilter: ipvs: fix incorrect conflict resolutionFlorian Westphal
The commit ab8bc7ed864b9c4f1fcb00a22bbe4e0f66ce8003 ("netfilter: remove nf_ct_is_untracked") changed the line if (ct && !nf_ct_is_untracked(ct) && nfct_nat(ct)) { to if (ct && nfct_nat(ct)) { meanwhile, the commit 41390895e50bc4f28abe384c6b35ac27464a20ec ("netfilter: ipvs: don't check for presence of nat extension") from ipvs-next had changed the same line to if (ct && !nf_ct_is_untracked(ct) && (ct->status & IPS_NAT_MASK)) { When ipvs-next got merged into nf-next, the merge resolution took the first version, dropping the conversion of nfct_nat(). While this doesn't cause a problem at the moment, it will once we stop adding the nat extension by default.
