Pull arm swiotlb support from Christoph Hellwig:
 "This fixes a cascade of regressions that originally started with the
  addition of the ia64 port, but only got fatal once we removed most
  uses of block layer bounce buffering in Linux 4.18.

  The reason is that while the original i386/PAE code that was the first
  architecture that supported > 4GB of memory without an iommu decided
  to leave bounce buffering to the subsystems, which in those days just
  mean block and networking as no one else consumed arbitrary userspace
  memory.

  Later with ia64, x86_64 and other ports we assumed that either an
  iommu or something that fakes it up ("software IOTLB" in beautiful
  Intel speak) is present and that subsystems can rely on that for
  dealing with addressing limitations in devices. Except that the ARM
  LPAE scheme that added larger physical address to 32-bit ARM did not
  follow that scheme and thus only worked by chance and only for block
  and networking I/O directly to highmem.

  Long story, short fix - add swiotlb support to arm when build for LPAE
  platforms, which actuallys turns out to be pretty trivial with the
  modern dma-direct / swiotlb code to fix the Linux 4.18-ish regression"

Looks like a regression got introduced into nv50_mstc_atomic_check()
that somehow didn't get found until now. If userspace changes
crtc_state->active to false but leaves the CRTC enabled, we end up
calling drm_dp_atomic_find_vcpi_slots() using the PBN calculated in
asyh->dp.pbn. However, if the display is inactive we end up calculating
a PBN of 0, which inadvertently causes us to have an allocation of 0.
>From there, if userspace then disables the CRTC afterwards we end up
accidentally attempting to free the VCPI twice:

that VCPI allocations remain for as long as the CRTC is enabled.

add_gpu_components() adds found GPU nodes from the DT to the match list,
regardless of the status of the nodes.  This is a problem, because if the
nodes are disabled, they should not be on the match list because they will
not be matched.  This prevents display from initing if a GPU node is
defined, but it's status is disabled.

Fix this by checking the node's status before adding it to the match list.

The mdp5 drm/kms driver currently does not work on command-mode DSI
panels due to 'vblank wait timed out' errors. This causes a latency
of seconds, or tens of seconds in some cases, before content is shown
on the panel. This hardware does not have the something that we can use
as a frame counter available when running in command mode, so we need to
fall back to using timestamps by setting the max_vblank_count to zero.
This can be done on a per-CRTC basis, so the convert mdp5 to use
drm_crtc_set_max_vblank_count().

This change was tested on a LG Nexus 5 (hammerhead) phone.

[subject was: drm/msm: shake fist angrily at dma-mapping]

So, using dma_sync_* for our cache needs works out w/ dma iommu ops, but
it falls appart with dma direct ops.  The problem is that, depending on
display generation, we can have either set of dma ops (mdp4 and dpu have
iommu wired to mdss node, which maps to toplevel drm device, but mdp5
has iommu wired up to the mdp sub-node within mdss).

issue since an actual value will get written later but this means
there's a chance of triggering a bug if we use this value with

  tracing: Fix header include guards in trace event headers

Pull IPMI fix from Corey Minyard:
 "One necessary fix for an uninitialized variable in the new IPMB driver.

  Nothing else has come in besides things that need to wait until later"

* tag 'for-linus-5.3-2' of git://github.com/cminyard/linux-ipmi:
  Fix uninitialized variable in ipmb_dev_int.c

In "consolidate the capability checks in sget_{fc,userns}())" the
wrong argument had been passed to mount_capable() by sget_fc().
That mistake had been further obscured later, when switching
mount_capable() to fs_context has moved the calculation of
bogus argument from sget_fc() to mount_capable() itself.  It
should've been fc->user_ns all along.

No VCN DPM bit check as that's different from VCN PG. Also
no extra check for possible double enablement/disablement
as that's already done by VCN.

Coccinelle reports a path that the array "data" is never initialized.
The path skips the checks in the conditional branches when either
of callback functions, read_wave_vgprs and read_wave_sgprs, is not
registered. Later, the uninitialized "data" array is read
in the while-loop below and passed to put_user().

Fix the path by allocating the array with kcalloc().

The patch is simplier than adding a fall-back branch that explicitly
calls memset(data, 0, ...). Also it does not need the multiplication
1024*sizeof(*data) as the size parameter for memset() though there is
no risk of integer overflow.

We already have tested it before. The second one should be removed.
With this change, the performance should have little improvement.
