8ce9daf885 drm: Fix fall-through warnings for Clang
In preparation to enable -Wimplicit-fallthrough for Clang, fix a warning
by explicitly adding a break statement instead of letting the code fall
through to the next case.

d963ab0f15 dma-buf: system_heap: Allocate higher order pages if available
While the system heap can return non-contiguous pages,
try to allocate larger order pages if possible.

This will allow slight performance gains and make implementing
page pooling easier.

4c68e499bb dma-buf: heaps: Skip sync if not mapped
This patch is basically a port of Ørjan Eide's similar patch for ION
 https://lore.kernel.org/lkml/20200414134629.54567-1-orjan.eide@arm.com/

Only sync the sg-list of dma-buf heap attachment when the attachment
is actually mapped on the device.

dma-bufs may be synced at any time. It can be reached from user space
via DMA_BUF_IOCTL_SYNC, so there are no guarantees from callers on when
syncs may be attempted, and dma_buf_end_cpu_access() and
dma_buf_begin_cpu_access() may not be paired.

Since the sg_list's dma_address isn't set up until the buffer is used
on the device, and dma_map_sg() is called on it, the dma_address will be
NULL if sync is attempted on the dma-buf before it's mapped on a device.

Before v5.0 (commit 55897af630 ("dma-direct: merge swiotlb_dma_ops
into the dma_direct code")) this was a problem as the dma-api (at least
the swiotlb_dma_ops on arm64) would use the potentially invalid
dma_address. How that failed depended on how the device handled physical
address 0. If 0 was a valid address to physical ram, that page would get
flushed a lot, while the actual pages in the buffer would not get synced
correctly. While if 0 is an invalid physical address it may cause a
fault and trigger a crash.

In v5.0 this was incidentally fixed by commit 55897af630 ("dma-direct:
merge swiotlb_dma_ops into the dma_direct code"), as this moved the
dma-api to use the page pointer in the sg_list, and (for Ion buffers at
least) this will always be valid if the sg_list exists at all.

But, this issue is re-introduced in v5.3 with
commit 449fa54d68 ("dma-direct: correct the physical addr in
dma_direct_sync_sg_for_cpu/device") moves the dma-api back to the old
behaviour and picks the dma_address that may be invalid.

dma-buf core doesn't ensure that the buffer is mapped on the device, and
thus have a valid sg_list, before calling the exporter's
begin_cpu_access.

3812957587 dma-buf: system_heap: Rework system heap to use sgtables instead of pagelists
In preparation for some patches to optmize the system
heap code, rework the dmabuf exporter to utilize sgtables rather
then pageslists for tracking the associated pages.

This will allow for large order page allocations, as well as
more efficient page pooling.

In doing so, the system heap stops using the heap-helpers logic
which sadly is not quite as generic as I was hoping it to be, so
this patch adds heap specific implementations of the dma_buf_ops
function handlers.

f0aee45ffc drm/panel: s6e63m0: Fix init sequence
The init sequence consist of a number of unknown settings
for the display controller. This patch achieves two things:

- Fix an error that must have happened when the driver was
  converted from the backlight subsystem: the 0xb8
  configuration command was lost and added as a tail to
  the previous command.

- Update some minor settings in some bytes here and there
  according to changes in the Samsung GT-I9070 and
  Samsung GT-S7710 code dumps. Since two other devices use
  these settings they probably reflect trimmings later
  found to be better for the display rather than
  customizations for these devices.

drm: Pass the full state to connectors atomic functions
The current atomic helpers have either their object state being passed as
an argument or the full atomic state.

The former is the pattern that was done at first, before switching to the
latter for new hooks or when it was needed.

Now that the CRTCs have been converted, let's move forward with the
connectors to provide a consistent interface.

The conversion was done using the coccinelle script below, and built tested
on all the drivers.

adds a workaround for a bug in mmap_region.

As the comment states ->mmap() callback can change
vma->vm_file and so we might call fput() on the wrong file.

Revert the workaround and proper fix this in mmap_region.

v2: drop the extra if in dma_buf_mmap as well

f9f92e7c58 char/agp: Disable frontend without CONFIG_DRM_LEGACY
It's probably full of bugs ready for exploiting by userspace. And
there's not going to be any userspace for this without any of the drm
legacy drivers enabled too. So just couple it together.

Note that the frontend is only the /dev/agp ioctl interface, which per
Adam is only used by the i810 userspace drivers. All other drivers go
through the drm bufmap agp handling abstraction apparently.

v2: Augment commit message a bit from m-l feedback.
