2017-03-07drm/nouveau/priv: punt messages to debug levelBen Skeggs
Ideally we'd be able to keep these at a more obvious error level, as they're a good indication of us doing something wrong. However, NVIDIA's FECS/GPCCS firmware touches registers that trigger priv ring faults, and we can't do anything to fix that ourselves due to the need for them to be signed by NVIDIA. This issue was reported a while back, but hasn't been fixed, so, for now we will hide the messages to prevent spamming Optimus users with messages whenever the NVIDIA GPU is powered off and on again.

very old qxl hardware revisions (predating qxl ksm support by a few years) supported a fixed list of video modes only.

2017-03-07drm: qxl: Don't alloc fbdev if emulation is not supportedGabriel Krisman Bertazi
If fbdev emulation is disabled, the QXL shutdown path will try to clean a framebuffer that wasn't initialized, hitting the Oops below. The problem is that even when FBDEV_EMULATION is disabled we allocate the qfbdev strutucture, but we don't initialize it. The fix is to stop allocating the memory, since it won't be used. This allows the existing verification in the cleanup hook to do it's job preventing the oops. Now that we don't allocate the unused fbdev structure, we need to be careful when dereferencing it in the PM suspend hook.

2017-03-06scsi: lpfc: Fix eh_deadline setting for sli3 adapters.James Smart
A previous change unilaterally removed the hba reset entry point from the sli3 host template. This was done to allow tape devices being used for back up from being removed. Why was this done ? When there was non-responding device on the fabric, the error escalation policy would escalate to the reset handler. When the reset handler was called, it would reset the adapter, dropping link, thus logging out and terminating all i/o's - on any target. If there was a tape device on the same adapter that wasn't in error, it would kill the tape i/o's, effectively killing the tape device state. With the reset point removed, the adapter reset avoided the fabric logout, allowing the other devices to continue to operate unaffected. A hack - yes. Hint: we really need a transport I_T nexus reset callback added to the eh process (in between the SCSI target reset and hba reset points), so a fc logout could occur to the one bad target only and stop the error escalation process. This patch commonizes the approach so it can be used for sli3 and sli4 adapters, but mandates the admin, via module parameter, specifically identify which adapters the resets are to be removed for. Additionally, bus_reset, which sends Target Reset TMFs to all targets, is also removed from the template as it too has the same effect as the adapter reset.

2017-03-06scsi: lpfc: remove redundant assignment of sgelJames Smart
From: Colin Ian King <colin.king@canonical.com> In the NVMET_FCOP_RSP case, sgel is assigned but never used and hence is redundant and can be removed.

git://anongit.freedesktop.org/git/drm-misc into drm-next First slice of drm-misc-next for 4.12: Core/subsystem-wide: - link status core patch from Manasi, for signalling link train fail to userspace. I also had the i915 patch in here, but that had a small buglet in our CI, so reverted. - more debugfs_remove removal from Noralf, almost there now (Noralf said he'll try to follow up with the stragglers). - drm todo moved into kerneldoc, for better visibility (see Documentation/gpu/todo.rst), lots of starter tasks in there. - devm_ of helpers + use it in sti (from Ben Gaignard, acked by Rob Herring) - extended framebuffer fbdev support (for fbdev flipping), and vblank wait ioctl fbdev support (Maxime Ripard) - misc small things all over, as usual - add vblank callbacks to drm_crtc_funcs, plus make lots of good use of this to simplify drivers (Shawn Guo) - new atomic iterator macros to unconfuse old vs. new state Small drivers: - vc4 improvements from Eric - vc4 kerneldocs (Eric)! - tons of improvements for dw-mipi-dsi in rockchip from John Keeping and Chris Zhong. - MAINTAINERS entries for drivers managed in drm-misc. It's not yet official, still an experiment, but definitely not complete fail and better to avoid confusion. We kinda screwed that up with drm-misc a bit when we started committers last year. - qxl atomic conversion (Gabriel Krisman) - bunch of virtual driver polish (qxl, virgl, ...) - misc tiny patches all over This is the first time we've done the same merge-window blackout for drm-misc as we've done for drm-intel for ages, hence why we have a _lot_ of stuff queued already. But it's still only half of drm-intel (room to grow!), and the drivers in drm-misc experiment seems to work at least insofar as that you also get lots of driver updates here alredy. * tag 'drm-misc-next-2017-03-06' of git://anongit.freedesktop.org/git/drm-misc: (141 commits) drm/vc4: Fix OOPSes from trying to cache a partially constructed BO. drm/vc4: Fulfill user BO creation requests from the kernel BO cache.

2017-03-06scsi: lpfc: replace init_timer by setup_timerTomas Jasek
This patch shortens every init_timer in lpfc module followed by function and data assignment using setup_timer. This is purely cleanup patch, it does not add new functionality nor remove any existing functionality. An init_timer call in this form: init_timer(&vport->fc_disctmo); vport->fc_disctmo.function = lpfc_disc_timeout; vport->fc_disctmo.data = vport; is shortened to: setup_timer(&vport->fc_disctmo, lpfc_disc_timeout, vport); It increases readability and reduces chances of mistakes done by developers.

2017-03-06scsi: qedi: fix build error without DEBUG_FSArnd Bergmann
Without CONFIG_DEBUG_FS, we run into a link error: drivers/scsi/qedi/qedi_iscsi.o: In function `qedi_ep_poll': qedi_iscsi.c:(.text.qedi_ep_poll+0x134): undefined reference to `do_not_recover' drivers/scsi/qedi/qedi_iscsi.o: In function `qedi_ep_disconnect': qedi_iscsi.c:(.text.qedi_ep_disconnect+0x36c): undefined reference to `do_not_recover' drivers/scsi/qedi/qedi_iscsi.o: In function `qedi_ep_connect': qedi_iscsi.c:(.text.qedi_ep_connect+0x350): undefined reference to `do_not_recover' drivers/scsi/qedi/qedi_fw.o: In function `qedi_tmf_work': qedi_fw.c:(.text.qedi_tmf_work+0x3b4): undefined reference to `do_not_recover' This defines the symbol as a constant in this case, as there is no way to set it to anything other than zero without DEBUG_FS. In addition, I'm renaming it to qedi_do_not_recover in order to put it into a driver specific namespace, as "do_not_recover" is a really bad name for a kernel-wide global identifier when it is used only in one driver.
