[PATCH v4 7/8] drm/nouveau: Fix deadlocks in nouveau_connector_detect()

by Lyude Paul

When we disable hotplugging on the GPU, we need to be able to synchronize with each connector's hotplug interrupt handler before the interrupt is finally disabled. This can be a problem however, since nouveau_connector_detect() currently grabs a runtime power reference when handling connector probing. This will deadlock the runtime suspend handler like so: [ 861.480896] INFO: task kworker/0:2:61 blocked for more than 120 seconds.

Interestingly while the deficiency has been there forever, it only started showing up after 4.17 dma common ops rework, commit a8eb92d02dd7 ("arc: fix arc_dma_{map,unmap}_page") which wired up these calls under the more commonly used dma_map_page API triggering the issue.

[char-misc-next] mei: ignore not found client in the enumeration

by Tomas Winkler

From: Alexander Usyskin <alexander.usyskin(a)intel.com> Some of the ME clients are available only for BIOS operation and are removed during hand off to an OS. However the removal is not instant. A client may be visible on the client list when the mei driver requests for enumeration, while the subsequent request for properties will be answered with client not found error value. The default behavior for an error is to perform client reset while this error is harmless and the link reset should be prevented. This issue started to be visible due to suspend/resume timing changes. Currently reported only on the Haswell based system. Fixes: [33.564957] mei_me 0000:00:16.0: hbm: properties response: wrong status = 1 CLIENT_NOT_FOUND [33.564978] mei_me 0000:00:16.0: mei_irq_read_handler ret = -71.

[PATCH] ARC: AXS10x/HSDK: Allow U-Boot to pass MAC-address to the kernel

by Alexey Brodkin

Otherwise kernel uses random MAC which is not very conveniet. With that change in place use might set desired MAC in U-Boot with "setenv ethaddr 11:22:33:44:55:66", save environment and then from boot to boot the same MAC will be used by the kernel. One other note for this to happen it's required to pass board's .dtb in U-Boot's "bootm" command like that: ------------------->8----------------- bootm 0x82000000 - 0x84000000 ------------------->8----------------- Here 0x82000000 is location of uImage while 0x80000000 is location of either axs10x.dtb or hsdk.dtb previously loaded from SD-card, USB storage or TFTP server.

[PATCH] x86/irqflags: provide a declaration for native_save_fl

by Nick Desaulniers

Fixes commit d0a8d9378d16 ("x86/paravirt: Make native_save_fl() extern inline"). It was reported that the above commit was causing users of gcc < 4.9 to observe -Werror=missing-prototypes errors. Indeed, it seems that: extern inline unsigned long native_save_fl(void) { return 0; } compiled with -Werror=missing-prototypes produces this warning in gcc < 4.9, but not gcc >= 4.9.
