Ensure that any queued events are issued when disabling the crtc. This
avoids timeouts when we come back and wait for dependencies (like the

With the addition of "private_objs" in drm_atomic_state, we no longer
need to subclass drm_atomic_state to store state of share resources
that don't perfectly fit within planes/crtc/connector state information.
We can now save this state within drm_atomic_state itself using
the private objects.
Remove the infrastructure that allowed subclassing of drm_atomic_state
in the driver.

This replaces the usage of the subclassed atomic state (mdp5_state)
with a private_obj state embedded within drm_atomic_state. The latter
method is the preferred approach, since it's simpler to implement
and less prone to errors.
The new API replaces the older and equivalent mdp5_state usage in the
following pattern:
- References to "mdp5_kms->state" (i.e, the old/existing state) is
replaced with mdp5_get_existing_global_state(). In the atomic_check
path, this should be called with the glob_state_lock drm_modeset_lock
alredy taken.
- References to "mdp5_get_state()" are replaced with
mdp5_get_global_state(). This acquires glob_state_lock and uses
drm_atomic_get_private_obj_state() to create a new duplicated state.
Changes in v3:
- Acquire glob_state_lock in mdp5_smp.c
- Added to the msm atomic helper patch set
Changes in v4:
- None

Global shared resources (hwpipes, hwmixers and SMP) for MDP5 are
implemented as a part of atomic state by subclassing drm_atomic_state.
The preferred approach is to use the drm_private_obj infrastructure
available in the atomic core.
mdp5_global_state is introduced as a drm atomic private object. The two
funcs mdp5_get_global_state() and mdp5_get_existing_global_state() are
the two variants that will be used to access mdp5_global_state.
This will replace the existing mdp5_state struct (which subclasses
drm_atomic_state) and the funcs around it. These will be removed later
once we mdp5_global_state is put to use everywhere.
Changes in v3:
- Added glob_state_lock instead of pushing it into the core
- Added to the msm atomic helper patch set
Changes in v4:
- None

Even though msm_gem_put_iova() is currently a NOP function, the caller
should pass in the address space pointer it used to obtain the object.
Other call sites were changed in 8bdcd949bbe7e ("drm/msm: pass
address-space to _get_iova() and friends"), but this one seems to have

Currently the error pointer returned by msm_alloc_stolen_fb gets passed
to drm_framebuffer_remove. The latter handles only NULL pointers, thus
a nasty crash will occur.
Drop the unnecessary fail label and the associated checks - both err and
fb will be set at this stage.

Commit 62e3a3e342af changed get_pages() to initialise
msm_gem_object::pages before trying to initialise msm_gem_object::sgt,
so that put_pages() would properly clean up pages in the failure
case.
However, this means that put_pages() now needs to check that
msm_gem_object::sgt is not null before trying to clean it up, and
this check was only applied to part of the cleanup code. Move
it all into the conditional block. (Strictly speaking we don't
need to make the kfree() conditional, but since we can't avoid
checking for null ourselves we may as well do so.)

- Regression fix addressing support for the new NVDIMM label storage
area access commands (_LSI, _LSR, and _LSW).

However, these new commands (standardized in ACPI 6.2) communicate
the "Device Locked" status on the label-storage-read command, and
the driver was missing the indication.
Reading from locked persistent memory is similar to reading
unmapped PCI memory space, returns all 1's.

Locked" detection failure.

Some of the mport_dma_req structure members were initialized late
inside the do_dma_request() function, just before submitting the
request to the dma engine. But we have some error branches before
that. In case of such an error, the code would return on the error
path and trigger the calling of dma_req_free() with a req structure
which is not completely initialized. This causes a NULL pointer
dereference in dma_req_free().
This patch fixes these error branches by making sure that all
necessary mport_dma_req structure members are initialized in
rio_dma_transfer() immediately after the request structure gets
allocated.

to eliminate special casing between device-dax and fs-dax as to when the
flag can be specified. Device-dax users already implicitly assume that they do
not need to call fsync(), and this enables them to explicitly check for this
capability.

Remove the direct dependency on of_node_to_nid() by using dev_to_node()
instead. Any DT platform device will have its NUMA node id set when the
device is created.
With this, commit 291717b6fbdb ("libnvdimm, of_pmem: workaround OF_NUMA=n
build error") can be reverted.

In some firmware images, the length of BNX_DIR_TYPE_PKG_LOG nvram type
could be greater than the fixed buffer length of 4096 bytes allocated by
the driver. This was causing HWRM_NVM_READ to copy more data to the buffer
than the allocated size, causing general protection fault.
Fix the issue by allocating the exact buffer length returned by
HWRM_NVM_FIND_DIR_ENTRY, instead of 4096. Move the kzalloc() call
into the bnxt_get_pkgver() function.

Programming vids (adding or removing them) still passes
guest-endian values in the DMA buffer. That's wrong
if guest is big-endian and when virtio 1 is enabled.

When sending control commands, virtio net sets up several buffers for
DMA. The buffers are all part of the net device which means it's
actually allocated by kvmalloc so it's in theory (on extreme memory
pressure) possible to get a vmalloc'ed buffer which on some platforms
means we can't DMA there.
Fix up by moving the DMA buffers into a separate structure.

When longer interface names are used, the action names exposed in
/proc/interrupts and /proc/irq/* maybe truncated. For example, when
using the predictable name algorithm in systemd on a HiSilicon D05,
I see:
ubuntu@d05-3:~$ grep enahisic2i0-tx /proc/interrupts | sed 's/.* //'
enahisic2i0-tx0
enahisic2i0-tx1
[...]
enahisic2i0-tx8
enahisic2i0-tx9
enahisic2i0-tx1
enahisic2i0-tx1
enahisic2i0-tx1
enahisic2i0-tx1
enahisic2i0-tx1
enahisic2i0-tx1
Increase the max ring name length to allow for an interface name
of IFNAMSIZE. After this change, I now see:
$ grep enahisic2i0-tx /proc/interrupts | sed 's/.* //'
enahisic2i0-tx0
enahisic2i0-tx1
enahisic2i0-tx2
[...]

vmxnet3_get_hdr_len() is used to calculate the header length which in
turn is used to calculate the gso_size for skb. When rxvlan offload is
disabled, vlan tag is present in the header and the function references
ip header from sizeof(ethhdr) and leads to incorrect pointer reference.
This patch fixes this issue by taking sizeof(vlan_ethhdr) into account
if vlan tag is present and correctly references the ip hdr.

is never checked in descriptor rx_status callback. This will cause
stmmac to always strip packets even that ACS feature is already
