In some cases the CCB DMA-based internal transfer started by the MOVE command (src=M3 register, dst=descriptor buffer) does not finish in time and DECO executes the unpatched descriptor. This leads eventually to a DECO Watchdog Timer timeout error. To make sure the transfer ends, change the MOVE command to be blocking.

Management Complex (MC) f/w detection is based on CTPR_MS[DPAA2] bit. This is incorrect since: -the bit is set for all CAAM blocks integrated in SoCs with a certain Layerscape Chassis -some SoCs with LS Chassis don't have an MC block (thus no MC f/w) To fix this, MC f/w detection will be based on the presence of "fsl,qoriq-mc" compatible string in the device tree.

2018-05-31crypto: clarify licensing of OpenSSL asm codeAdam Langley
Several source files have been taken from OpenSSL. In some of them a comment that "permission to use under GPL terms is granted" was included below a contradictory license statement. In several cases, there was no indication that the license of the code was compatible with the GPLv2. This change clarifies the licensing for all of these files. I've confirmed with the author (Andy Polyakov) that a) he has licensed the files with the GPLv2 comment under that license and b) that he's also happy to license the other files under GPLv2 too. In one case, the file is already contained in his CRYPTOGAMS bundle, which has a GPLv2 option, and so no special measures are needed. In all cases, the license status of code has been clarified by making the GPLv2 license prominent. The .S files have been regenerated from the updated .pl files. This is a comment-only change. No code is changed. Signed-off-by: Adam Langley <agl@chromium.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2018-05-30cpufreq: Add Kryo CPU scaling driverIlia Lin
In Certain QCOM SoCs like apq8096 and msm8996 that have KRYO processors, the CPU frequency subset and voltage value of each OPP varies based on the silicon variant in use. Qualcomm Process Voltage Scaling Tables defines the voltage and frequency value based on the msm-id in SMEM and speedbin blown in the efuse combination. The qcom-cpufreq-kryo driver reads the msm-id and efuse value from the SoC to provide the OPP framework with required information. This is used to determine the voltage and frequency value for each OPP of operating-points-v2 table when it is parsed by the OPP framework.

2018-05-30s390/zcrypt: Fix CCA and EP11 CPRB processing failure memory leak.Harald Freudenberger
Tests showed, that the zcrypt device driver produces memory leaks when a valid CCA or EP11 CPRB can't get delivered or has a failure during processing within the zcrypt device driver. This happens when a invalid domain or adapter number is used or the lower level software or hardware layers produce any kind of failure during processing of the request. Only CPRBs send to CCA or EP11 cards can produce this memory leak. The accelerator and the CPRBs processed by this type of crypto card is not affected. The two fields message and private within the ap_message struct are allocated with pulling the function code for the CPRB but only freed when processing of the CPRB succeeds. So for example an invalid domain or adapter field causes the processing to fail, leaving these two memory areas allocated forever.

2018-05-30cpufreq: Fix new policy initialization during limits updates via sysfsTao Wang
If the policy limits are updated via cpufreq_update_policy() and subsequently via sysfs, the limits stored in user_policy may be set incorrectly. For example, if both min and max are set via sysfs to the maximum available frequency, user_policy.min and user_policy.max will also be the maximum. If a policy notifier triggered by cpufreq_update_policy() lowers both the min and the max at this point, that change is not reflected by the user_policy limits, so if the max is updated again via sysfs to the same lower value, then user_policy.max will be lower than user_policy.min which shouldn't happen. In particular, if one of the policy CPUs is then taken offline and back online, cpufreq_set_policy() will fail for it due to a failing limits check. To prevent that from happening, initialize the min and max fields of the new_policy object to the ones stored in user_policy that were previously set via sysfs.

2018-05-30iwlwifi: mvm: fix race in queue notification waitJohannes Berg
Initially in this code, the race didn't matter since it didn't do anything. Latest with the commit I marked this as fixing it started to matter as something got done here that needed other data that got freed as soon as the queue notification wait was returning. In the scenario we saw, apparently the IWL_MVM_RXQ_NOTIF_DEL_BA event was sent to all queues, but processing the last event we returned from iwl_mvm_sync_rx_queues_internal() and then from iwl_mvm_free_reorder() and continued some processing before wl_mvm_del_ba() was even invoked on the other CPU. Thus, when the latter finally ran, it found that mvm->baid_map[baid] was no longer valid. Correct the race by moving the counter decrement and wake_up() to be done only after all the per-event processing completed. Note that in the commit I marked as being fixed the wake_up() didn't exist yet (and the code was otherwise problematic) but this particular problem already existed in a way.

2018-05-30HID: multitouch: fix calculation of last slot field in multi-touch reportsBen Chan
According to [1] and also seemingly agreed by [2], the Scan Time usage (0x0D 0x56) is a report level usage, not a contact level usage. However, the hid-multitouch driver currently includes HID_DG_SCANTIME when calculating `td->last_slot_field', which may lead to mt_complete_slot() being prematurely called in certain cases (e.g. when each touch input report includes more than one contact and the Scan Time usage appears before any contact logical collection). This patch fixes the issue by skipping mt_store_field() on HID_DG_SCANTIME, similar to how HID_DG_CONTACTCOUNT and HID_DG_CONTACTMAX are handled.

2018-05-30iwlwifi: pcie: fix race in Rx buffer allocatorShaul Triebitz
Make sure the rx_allocator worker is canceled before running the rx_init routine. rx_init frees and re-allocates all rxb's pages. The rx_allocator worker also allocates pages for the used rxb's. Running rx_init and rx_allocator simultaniously causes a kernel panic. Fix that by canceling the work in rx_init.

2018-05-30iwlwifi: mvm: fix TSO with highly fragmented SKBsEmmanuel Grumbach
Our hardware has a limited amount of buffer descriptors for each Tx packet. Because of that, there is a short piece of code that makes sure that that we don't push too many subframes in an A-MSDU because of subframes needs 2 buffer descriptors. This code also takes into account the number of fragment of the skb since we also need a buffer descriptor for each fragment in the skb. This piece of code though didn't check that the resulting number of subframes wasn't 0. A user reported that using NFS client, he could get skbs that are so fragmented that the code mentioned above returned 0 for the number of subframes making skb_gso_segment fail and subconsequently iwlwifi would WARN. Fix this by make sure that num_subframes is at least 1.

2018-05-30thermal: int340x: Prevent error in reading trip hysteresis attributeSrinivas Pandruvada
Some of the INT340X devices may not have hysteresis defined in the ACPI definition. In that case reading trip hysteresis results in error. This spams logs of user space utilities. In this case instead of returning error, just return hysteresis as 0, which is correct as there is no hysteresis defined for the device.

2018-05-30iwlwifi: mvm: drop UNKNOWN security type framesSara Sharon
In some cases we may get from FW errored frames with UNKNOWN security type. This may happen in unsecured aggregation flow, where the first packet had a CRC error in the WEP bit, which was followed by a failure to decrypt and was dropped. The next frames in the aggregation "inherit" the bad metadata of the first packet. Make sure to drop such frames since RADA and other offloads will not operate correctly which may have unexpected results. In case of AP it also causes to TX AMSDU frames to the peers, resulting with assert 0x104B. Signed-off-by: Sara Sharon <sara.sharon@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
