Linus Torvalds 1731a47444 - A few DM integrity fixes that improve performance. One that address
inefficiencies in the on-disk journal device layout.  Another that
   makes use of the block layer's on-stack plugging when writing the
   journal.
 
 - A dm-bufio fix for the blk_status_t conversion that went in during the
   merge window.
 
 - A few DM raid fixes that address correctness when suspending the
   device and a validation fix for validation that occurs during device
   activation.
 
 - A couple DM zoned target fixes.  Important one being the fix to not
   use GFP_KERNEL in the IO path due to concerns about deadlock in
   low-memory conditions (e.g. swap over a DM zoned device, etc).
 
 - A DM DAX device fix to make sure dm_dax_flush() is called if the
   underlying DAX device is operating as a write cache.

Pull block fixes from Jens Axboe:
 "A small collection of fixes that should go into this series. This
  contains:

   - NVMe pull request from Christoph, with various fixes for nvme
     proper and nvme-fc.

   - disable runtime PM for blk-mq for now.

     With scsi now defaulting to using blk-mq, this reared its head as
     an issue. Longer term we'll fix up runtime PM for blk-mq, for now
     just disable it to prevent a hang on laptop resume for some folks.

   - blk-mq CPU <-> hw queue map fix from Christoph.

   - xen/blkfront pull request from Konrad, with two small fixes for the
     blkfront driver.

   - a few fixups for nbd from Joseph.

   - a stable fix for pblk from Javier"

Javier González 75cb8e939c lightnvm: pblk: advance bio according to lba index
When a lba either hits the cache or corresponds to an empty entry in the
L2P table, we need to advance the bio according to the position in which
the lba is located. Otherwise, we will copy data in the wrong page, thus
causing data corruption for the application.

In case of a cache hit, we assumed that bio->bi_iter.bi_idx would
contain the correct index, but this is no necessarily true. Instead, use
the local bio advance counter and iterator. This guarantees that lbas
hitting the cache are copied into the right bv_page.

In case of an empty L2P entry, we omitted to advance the bio. In the
cases when the same I/O also contains a cache hit, data corresponding
to this lba will be copied to the wrong bv_page. Fix this by advancing
the bio as we do in the case of a cache hit.

  As expected people woke up this week, i915 didn't do an -rc2 pull so
  got a bumper -rc3 pull, and Ben resurfaced on nouveau and fixed a
  bunch of major crashers seen on Fedora 26, and there are a few vmwgfx

Chris Wilson 7b98da6617 drm/i915: Force CPU synchronisation even if userspace requests ASYNC
The goal here was to minimise doing any thing or any check inside the
kernel that was not strictly required. For a userspace that assumes
complete control over the cache domains, the kernel is usually using
outdated information and may trigger clflushes where none were
required.

However, swapping is a situation where userspace has no knowledge of the
domain transfer, and will leave the object in the CPU cache. The kernel
must flush this out to the backing storage prior to use with the GPU. As
we use an asynchronous task tracked by an implicit fence for this, we
also need to cancel the ASYNC flag on the object so that the object will
wait for the clflush to complete before being executed. This also absolves
userspace of the responsibility imposed by commit 77ae995789 ("drm/i915:
Enable userspace to opt-out of implicit fencing") that its needed to ensure
that the object was out of the CPU cache prior to use on the GPU.

Chris Wilson adf27835a5 drm/i915: Only skip updating execobject.offset after error
I was being overly paranoid in not updating the execobject.offset after
performing the fallback copy where we set reloc.presumed_offset to -1.
The thinking was to ensure that a subsequent NORELOC execbuf would be
forced to process the invalid relocations. However this is overkill so
long as we *only* update the execobject.offset following a successful
update of the relocation value witin the batch. If we have to repeat the
execbuf due to a later interruption, then we may skip the relocations on
the second pass (honouring NORELOC) since the execobject.offset match
the actual offsets (even though reloc.presumed_offset is garbage).

Subsequent calls to execbuf with NORELOC should themselves ensure that
the reloc.presumed_offset have been corrected in case of future
migration.

Reporting back the actual execobject.offset, even when
reloc.presumed_offset is garbage, ensures that reuse of those objects
use the latest information to avoid relocations.

After we detect a i915_vma pin overflow, we call __i915_vma_unpin to
cleanup. However, on an overflow the pin_count bitfield will be zero,
triggering an assertion, even though we the intention is to merely warn
and report the error back to the user (as historically the culprit has
be a leak in the display code).

Imre Deak 283d6860d6 drm/i915: Fix scaler init during CRTC HW state readout
The scaler allocation code depends on a non-zero default value for the
crtc scaler_id, so make sure we initialize the scaler state accordingly
even if the crtc is off. This fixes at least an initial YUV420 modeset
(added in a follow-up patchset by Shashank) when booting with the screen
off: after the initial HW readout and modeset which enables the scaler a
subsequent modeset will disable the scaler which isn't properly
allocated. This results in a funky HW state where the pipe scaler HW
registers can't be modified and the normally black screen is grey and
shifted to the right or jitters.

The problem was revealed by Shashank's YUV420 patchset and first
reported by Ville.

Daniel Vetter 4706ca779a drm/i915: Unbreak gpu reset vs. modeset locking
Taking the modeset locks unconditionally isn't the greatest idea,
because atm that part is still broken and times out (and then atomic
keels over). And there's really no reason to do so, the old code
didn't do that either.

To make the patch a bit simpler let's also nuke 2 cases that are only
around for the old mmioflip paths. Atomic nonblocking workers will not
die (minus bugs) when a gpu reset happens.

And of course this doesn't fix any of the gpu reset vs. modeset
deadlock fun, but it at least stop modern CI machines from keeling
over all over the place for no reason at all.

And we still have the explicit testcases to run the fake gpu reset, so
coverage isn't that much worse.

v2: Split out additional changes on top, restrict this to purely reducing
the critical section of modeset locks.

v2: Review from Maarten
- update comments
- don't oops when state is NULL in intel_finish_reset, but try to at
  least still drop locks properly. The hw is going to be toast anyway.

Pull parisc fixes from Helge Deller:

 - The majority of lines changed are due to regenerated defconfig files.

 - The support for the Page Deallocation Table (PDT) which was merged in
   the merge window for 4.13 contained a bug which crashes the kernel if
   a bad page is reported by firmware. This is now fixed and the kernel
   messages will show which memory slot holds the broken DIMM.

 - Commit 3a166fc2d4 ("kbuild: handle libs-y archives separately from
   built-in.o archives") broke linking the parisc kernel due to
   millicode symbols which can't be reached then any longer. This was
   fixed by modifying the parisc vmlinux.lds linker script.

 - If the stack checker panics on stack overflow, avoid recursive
   panics.

 - Some parisc machines can't physically power off and thus instead
   start after some time to flood the console by presumably detected
   soft lockups. Avoid this by disabling the lockup detectors before
   entering the endless for-next loop.

 - Dave Anglin provided fixes which prevents TLB speculation on flushed
   pages on PA8800/PA9000 CPUs.

 - Arvind Yadav sent a trivial patch to constify the attribute_group
   structure in our firmware on-board-flash storage driver

Paul Kocialkowski fea2099597 gpu: host1x: Free the IOMMU domain when there is no device to attach
When there is no device to attach to the IOMMU domain, as may be the
case when the device-tree does not contain the proper iommu node, it is
best to keep going without IOMMU support rather than failing.
This allows the driver to probe and function instead of taking down
all of the tegra drm driver, leading to missing display support.

Ville Syrjälä d34cfebbf9 drm/i915: Fix cursor updates on some platforms
Turns out that just writing CURPOS isn't sufficient to move the cursor
on some platforms. My 830 works just fine, but eg. 945 and PNV don't.
On those platforms we need to arm even the CURPOS update with a
CURBASE write.

Even worse, a write to any of the cursor register apart from CURBASE
will cancel an already pending cursor update. So if we have armed a
CURCNTR/CURBASE update, a subsequent CURPOS write prior to vblank
would cancel that armed update. Thus we're left with a cursor that
doesn't appear to move, or even change shape.

Fix the problem by always performing the CURBASE write after a
CURPOS write. Bspec is somewhat unclear which platforms actually
require this CURBASE write and which don't. So to keep it simple
and to make sure we really fix the problem across all supported
devices, let's just perform the CURBASE write unconditionally.

Arnd Bergmann 7e17510018 drm: exynos: mark pm functions as __maybe_unused
The rework of the exynos DRM clock handling introduced
warnings for configurations that have CONFIG_PM disabled:

drivers/gpu/drm/exynos/exynos_hdmi.c:736:13: error: 'hdmi_clk_disable_gates' defined but not used [-Werror=unused-function]
 static void hdmi_clk_disable_gates(struct hdmi_context *hdata)
             ^~~~~~~~~~~~~~~~~~~~~~
drivers/gpu/drm/exynos/exynos_hdmi.c:717:12: error: 'hdmi_clk_enable_gates' defined but not used [-Werror=unused-function]
 static int hdmi_clk_enable_gates(struct hdmi_context *hdata)

The problem is that the PM functions themselves are inside of
an #ifdef, but some functions they call are not.

This patch removes the #ifdef and instead marks the PM functions
as __maybe_unused, which is a more reliable way to get it right.

NeilBrown 34c96507e8 dm verity fec: fix GFP flags used with mempool_alloc()
mempool_alloc() cannot fail for GFP_NOIO allocation, so there is no
point testing for failure.

One place the code tested for failure was passing "0" as the GFP
flags.  This is most unusual and is probably meant to be GFP_NOIO,
so that is changed.

Also, allocation from ->extra_pool and ->prealloc_pool are repeated
before releasing the previous allocation.  This can deadlock if the code
is servicing a write under high memory pressure.  To avoid deadlocks,
change these to use GFP_NOWAIT and leave the error handling in place.

Linus Torvalds cef55b518c dma mapping fixes for 4.13-rc2:
- split the global dma coherent pool from the per-device pool.
    This fixes a regression in the earlier 4.13 pull requests where the
    global pool would override a per-device CMA pool. (Vladimir Murzin).
