2017-11-13drm/amd/amdgpu: Fix wave mask in amdgpu_debugfs_wave_read() (v2)Tom St Denis
The bottom two bits of the simd value were being put into the upper bits of the wave value which was likely working due to the bits being ignored (or aliased). Eitherway, now we mask it correctly.

2017-11-13irqchip/gic-v3-its: Remove artificial dependency on PCIMarc Zyngier
The GICv3 ITS doesn't really depend on PCI. Only the PCI/MSI part of it does, and there is no reason not to blow away most of the irqchip stack because PCI is not selected (though not selecting PCI seem to be asking for punishment, but hey...). So let's split the PCI-specific part from the ITS in the Kconfig file, and let's make that part depend on PCI. Architecture specific hacks (arch/arm{,64}/Kconfig) will be addressed in a separate patch. Reported-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
2017-11-13fbcon: Initialize ops->info earlyThierry Reding
During console takeover, which happens for all DRM/KMS setups using the fbdev helpers, fbcon_startup() is called before fbcon_init() and as a result con2fb_acquire_newinfo() will not be called (info->fbcon_par was set to non-NULL in fbcon_startup()) to assign ops->info. This causes the cursor_timer_handler() to unreference a NULL pointer. Avoid this by unconditionally assigning ops->info during fbcon_startup() so that it will be available early, but keep the additional assignment in con2fb_acquire_newinfo() to support console remapping at runtime.

2017-11-13rbd: default to single-major device number schemeIlya Dryomov
It's been 3.5 years, let's turn it on by default. Support in rbd(8) utility goes back to pre-firefly, "rbd map" has been loading the module with single_major=Y ever since. However, if the module is already loaded (whether by hand or at boot time), we end up with single_major=N. Also, some people don't install rbd(8) and use the sysfs interface directly. (With single-major=N, a major number is consumed for every mapping, imposing a limit of ~240 rbd images per host. single-major=Y allows mapping thousands of rbd images on a single machine.)

https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Updates for v4.15 The biggest thing this release has been the conversion of the AC98 bus to the driver model, that's been a long time coming so thanks to Robert Jarzmik for his dedication there. Due to there being some AC97 MFD there's a few fairly large changes in input and the MFD layer, mainly to the wm97xx driver. There's also some drivers/drm changes to support the new AMD Stoney platform, these are shared with the DRM subsystem and should be being merged via both. Within the subsystem the overwhelming bulk of the changes is in the Intel drivers which continue to need lots of cleanups and fixes, this release they've also gained support for their open source firmware. There's also some large changs in the core as Morimoto-san continues to mirror operations into the component level in preparation for conversion of drivers to that. - The AC97 bus has finally caught up with the driver model thanks to some dedicated and persistent work from Robert Jarzmik. - Continued work from Morimoto-san on moving us towards being able to use components for everything. - Lots of cleanups for the Intel platform code, including support for their open source audio firmware. - Support for scaling MCLK with sample rate in simple-card. - Support for AMD Stoney platform.

2017-11-13rbd: set discard_alignment to zeroDavid Disseldorp
RBD devices are currently incorrectly initialised with the block queue discard_alignment set to the underlying RADOS object size. As per Documentation/ABI/testing/sysfs-block: The discard_alignment parameter indicates how many bytes the beginning of the device is offset from the internal allocation unit's natural alignment. Correcting the discard_alignment parameter from the RADOS object size to zero (the blk_set_default_limits() default) has no effect on how discard requests are propagated through the block layer - @alignment in __blkdev_issue_discard() remains zero. However, it does fix the UNMAP granularity alignment value advertised to SCSI initiators via the Block Limits VPD.

->open_count/-EBUSY check is bogus and wrong: when an open device is set read-only, blkdev_write_iter() refuses further writes with -EPERM. This is standard behaviour and all other block devices allow this. set_disk_ro() call is also problematic: we affect the entire device when called on a single partition. All rbd_ioctl_set_ro() needs to do is refuse ro -> rw transition for mapped snapshots. Everything else can be handled by generic code. Signed-off-by: Ilya Dryomov <idryomov@gmail.com>

2017-11-13net: dsa: b53: Support prepended Broadcom tagsFlorian Fainelli
On BCM58xx devices (Northstar Plus), there is an accelerator attached to port 8 which would only work if we use prepended Broadcom tags. Resolve that difference in our get_tag_protocol() function by setting the appropriate tagging protocol in that case. We need to change b53_brcm_hdr_setup() a little bit now since we can deal with two types of Broadcom tags.
