2018-06-21net: macb: Fix ptp time adjustment for large negative deltaHarini Katakam
When delta passed to gem_ptp_adjtime is negative, the sign is maintained in the ns_to_timespec64 conversion. Hence timespec_add should be used directly. timespec_sub will just subtract the negative value thus increasing the time difference.

2018-06-21ipvlan: fix IFLA_MTU ignored on NEWLINKXin Long
Commit 296d48568042 ("ipvlan: inherit MTU from master device") adjusted the mtu from the master device when creating a ipvlan device, but it would also override the mtu value set in rtnl_create_link. It causes IFLA_MTU param not to take effect. So this patch is to not adjust the mtu if IFLA_MTU param is set when creating a ipvlan device.

2018-06-21net: mscc: fix the injection headerAntoine Tenart
When injecting frames in the Ocelot switch driver an injection header (IFH) should be used to configure various parameters related to a given frame, such as the port onto which the frame should be departed or its vlan id. Other parameters in the switch configuration can led to an injected frame being sent without an IFH but this led to various issues as the per-frame parameters are then not used. This is especially true when using multiple ports for injection. The IFH was injected with the wrong endianness which led to the switch not taking it into account as the IFH_INJ_BYPASS bit was then unset. (The bit tells the switch to use the IFH over its internal configuration). This patch fixes it. In addition to the endianness fix, the IFH is also fixed. As it was (unwillingly) unused, some of its fields were not configured the right way.

2018-06-20nvme-rdma: Fix command completion race at error recoveryIsrael Rukshin
The race is between completing the request at error recovery work and rdma completions. If we cancel the request before getting the good rdma completion we get a NULL deref of the request MR at nvme_rdma_process_nvme_rsp(). When Canceling the request we return its mr to the mr pool (set mr to NULL) and also unmap its data. Canceling the requests while the rdma queues are active is not safe. Because rdma queues are active and we get good rdma completions that can use the mr pointer which may be NULL. Completing the request too soon may lead also to performing DMA to/from user buffers which might have been already unmapped. The commit fixes the race by draining the QP before starting the abort commands mechanism.

2018-06-20x86: Call fixup_exception() before notify_die() in math_error()Siarhei Liakh
fpu__drop() has an explicit fwait which under some conditions can trigger a fixable FPU exception while in kernel. Thus, we should attempt to fixup the exception first, and only call notify_die() if the fixup failed just like in do_general_protection(). The original call sequence incorrectly triggers KDB entry on debug kernels under particular FPU-intensive workloads.

2018-06-20HID: intel_ish-hid: ipc: register more pm callbacks to support hibernationEven Xu
Current ISH driver only registers suspend/resume PM callbacks which don't support hibernation (suspend to disk). Basically after hiberation, the ISH can't resume properly and user may not see sensor events (for example: screen rotation may not work). User will not see a crash or panic or anything except the following message in log: hid-sensor-hub 001F:8086:22D8.0001: timeout waiting for response from ISHTP device So this patch adds support for S4/hiberbation to ISH by using the SIMPLE_DEV_PM_OPS() MACRO instead of struct dev_pm_ops directly. The suspend and resume functions will now be used for both suspend to RAM and hibernation. If power management is disabled, SIMPLE_DEV_PM_OPS will do nothing, the suspend and resume related functions won't be used, so mark them as __maybe_unused to clarify that this is the intended behavior, and remove #ifdefs for power management.

When creating the low-level hidraw device, the reference to steam_device was stored using hid_set_drvdata(). But this value is not guaranteed to be kept when set before calling probe. If this pointer is reset, it crashes when opening the emulated hidraw device. It looks like hid_set_drvdata() is for users "avobe" this hid_device, while hid_device.driver_data it for users "below" this one.

2018-06-20proc: fix missing final NUL in get_mm_cmdline() rewriteLinus Torvalds
The rewrite of the cmdline fetching missed the fact that we used to also return the final terminating NUL character of the last argument. I hadn't noticed, and none of the tools I tested cared, but something obviously must care, because Michal Kubecek noticed the change in behavior. Tweak the "find the end" logic to actually include the NUL character, and once past the eend of argv, always start the strnlen() at the expected (original) argument end. This whole "allow people to rewrite their arguments in place" is a nasty hack and requires that odd slop handling at the end of the argv array, but it's our traditional model, so we continue to support it.
