2018-12-13ASoC: fsl: Fix SND_SOC_EUKREA_TLV320 build error on i.MX8MFabio Estevam
eukrea-tlv320.c machine driver runs on non-DT platforms and include <asm/mach-types.h> header file in order to be able to use some machine_is_eukrea_xxx() macros. Building it for ARM64 causes the following build error: sound/soc/fsl/eukrea-tlv320.c:28:10: fatal error: asm/mach-types.h: No such file or directory Avoid this error by not allowing to build the SND_SOC_EUKREA_TLV320 driver when ARM64 is selected. This is needed in preparation for the i.MX8M support.

2018-12-13net/mlx5e: Avoid encap flows deletion attempt the 1st time a neigh is resolvedOr Gerlitz
Currently, we are deleting offloaded encap flows in case the relevant neigh becomes unconnected while the encap is valid (a sign that it used to be connected), or if the curr neigh mac is different from the cached mac (a sign that the remote side changed their mac). The 2nd check also applies when the neigh becomes connected on the 1st time (we start with zero mac). Before the offending commit, the deleting handler was practically no op, as no flows were offloaded. But since that commit, we offload neigh-less encap flows to slow path. Under mirroring scheme, we go into the delete handler, attempt to unoffload a mirror rule which was never set (as we were offloading to slow path) and crash. Fix that by calling the delete handler only when the encap is valid, which covers both cases mentioned above.

2018-12-13platform/x86: add support for Huawei WMI hotkeysAyman Bagabas
This driver adds support for missing hotkeys on some Huawei laptops. Laptops such as the Matebook X have non functioning hotkeys. Whereas newer laptops such as the Matebook X Pro come with working hotkeys out of the box. Old laptops, such as the Matebook X, report hotkey events through ACPI device "\WMI0". However, new laptops, such as the Matebook X Pro, does not have this WMI device. All the hotkeys on the Matebook X Pro work fine without this patch except (micmute, wlan, and huawei key). These keys and the brightness keys report events to "\AMW0" ACPI device. One problem is that brightness keys on the Matebook X Pro work without this patch. This results in reporting two brightness key press events one is captured by ACPI and another by this driver. A solution would be to check if such event came from the "\AMW0" WMI driver then skip reporting event. Another solution would be to leave this to user-space to handle. Which can be achieved by using "hwdb" tables and remap those keys to "unknown". This solution seems more natural to me because it leaves the decision to user-space.

When boxes are run near (or to) OOM, we have a problem with the discard page allocation in sd. If we fail allocating the special page, we return busy, and it'll get retried. But since ordering is honored for dispatch requests, we can keep retrying this same IO and failing. Behind that IO could be requests that want to free memory, but they never get the chance. This means you get repeated spews of traces like this: [1201401.625972] Call Trace: [1201401.631748] dump_stack+0x4d/0x65 [1201401.639445] warn_alloc+0xec/0x190 [1201401.647335] __alloc_pages_slowpath+0xe84/0xf30 [1201401.657722] ? get_page_from_freelist+0x11b/0xb10 [1201401.668475] ? __alloc_pages_slowpath+0x2e/0xf30 [1201401.679054] __alloc_pages_nodemask+0x1f9/0x210 [1201401.689424] alloc_pages_current+0x8c/0x110 [1201401.699025] sd_setup_write_same16_cmnd+0x51/0x150 [1201401.709987] sd_init_command+0x49c/0xb70 [1201401.719029] scsi_setup_cmnd+0x9c/0x160 [1201401.727877] scsi_queue_rq+0x4d9/0x610 [1201401.736535] blk_mq_dispatch_rq_list+0x19a/0x360 [1201401.747113] blk_mq_sched_dispatch_requests+0xff/0x190 [1201401.758844] __blk_mq_run_hw_queue+0x95/0xa0 [1201401.768653] blk_mq_run_work_fn+0x2c/0x30 [1201401.777886] process_one_work+0x14b/0x400 [1201401.787119] worker_thread+0x4b/0x470 [1201401.795586] kthread+0x110/0x150 [1201401.803089] ? rescuer_thread+0x320/0x320 [1201401.812322] ? kthread_park+0x90/0x90 [1201401.820787] ? do_syscall_64+0x53/0x150 [1201401.829635] ret_from_fork+0x29/0x40 Ensure that the discard page allocation has a mempool backing, so we know we can make progress.

Mostly just initial support for Turing TU104/TU106 chipsets. Support for TU102 is missing as I don't yet have HW, but it should be trivial to add in later in the merge window (in theory). It's a bit of a rough first pass that'll get improved in future releases as a finish figuring out some of the other HW changes, but it's good enough as it stands for modesetting and suspend/resume etc. Acceleration bring-up is incomplete due to NVIDIA not yet having provided FW images for me to use, though command submission and copy engines are functional already.

Vlans are not getting removed when drivers are unloaded. The recent storm firmware versions had added safeguards against re-configuring an already configured vlan. As a result, PF inner reload flows (e.g., mtu change) might trigger an assertion. This change is going to remove vlans (same as we do for MACs) when doing a chip cleanup during unload.

2018-12-12ixgbe: Fix race when the VF driver does a resetRoss Lagerwall
When the VF driver does a reset, it (at least the Linux one) writes to the VFCTRL register to issue a reset and then immediately sends a reset message using the mailbox API. This is racy because when the PF driver detects that the VFCTRL register reset pin has been asserted, it clears the mailbox memory. Depending on ordering, the reset message sent by the VF could be cleared by the PF driver. It then responds to the cleared message with a NACK which causes the VF driver to malfunction. Fix this by deferring clearing the mailbox memory until the reset message is received.
