A failing usercopy of the fence_rep object will lead to a stale entry in
the file descriptor table as put_unused_fd() won't release it. This
enables userland to refer to a dangling 'file' object through that still
valid file descriptor, leading to all kinds of use-after-free
exploitation scenarios.
Fix this by deferring the call to fd_install() until after the usercopy
has succeeded.

The commit feeb07d0ca5a ("drm/hisilicon/hibmc: Make CONFIG_DRM_HISI_HIBMC
depend on ARM64") made the driver Kconfig symbol to depend on ARM64 since
it only supports that architecture and loading the module on others would
lead to incorrect video modes being used.
But it also prevented the driver to be built on other architectures which
is useful to have compile test coverage when doing subsystem wide changes.
Make the dependency instead to be (ARM64 || COMPILE_TEST), so the driver
is buildable when the CONFIG_COMPILE_TEST option is enabled.

The TCSS_DDI_STATUS register is indexed by tc_port not by the FIA port
index, fix this up. This only caused an issue on TC#3/4 ports in legacy

the TCSS_DDI_STATUS_READY flag is set regardless of something being
connected or not (on TC#1/2/3/4 in dp-alt and tbt-alt modes).

Starting from DG2, some of the programming previously done by i915 and
the GuC has been moved to the GSC and the relevant registers are no
longer writable by either CPU or GuC. This is also referred to as GuC
deprivilege.
On the i915 side, this affects the WOPCM registers: these are no longer
programmed by the driver and we do instead expect to find them already
set. This can lead to verification failures because in i915 we cheat a bit
with the WOPCM size defines, to keep the code common across platforms, by
sometimes using a smaller WOPCM size that the actual HW support (which isn't
a problem because the extra size is not needed if the FW fits in the smaller
chunk), while the pre-programmed values can use the actual size.
Given tha the new programming entity is trusted, relax the amount of the
checks done on the pre-programmed values by not limiting the max
programmed size. In the extremely unlikely scenario that the registers
have been misprogrammed, we will still fail later at DMA time.

Use REG_GENMASK() & co. when dealing with PIPESRC.
Note that i9xx_get_initial_plane_config() will now use the
full 16 bit mask whereas previously it used 12 bits only.
But intel_get_pipe_src_size() already used the full 16 bits
on all platforms anyway, so at least we're consistent now.
The high bits beyond the max supported pipe source size
should not be set in any case so this seems fine.

Since tgl PIPE_DSL has 20 bits for the scanline. Let's bump our
definition to match. And while at it let's also add the define
for the current field readback.
We can also get rid of the gen2 vs. gen3+ nonsense since none
of the extra bits ever did anything and just always read
as zero. And now we extend all platforms to use the tgl+
20 bits deinition, but again that is fine since all the bits
used to be mbz and always read as zero on all the platforms.

currently sits (ddi .pre_enable() or icl_ddi_bigjoiner_pre_enable())
into hsw_crtc_enable() where we write the other per-pipe stuff
as well. Makes the transcoder vs. pipe split less confusing.
For DSI this results in slight reordering between the dsc/joiner
enable vs. transcoder timings setup, but I can't really think
why that should cause any issues since the transcoder isn't yet
enabled at that point.

Pull the transcoder specific modeset steps into a single place.
With bigoiner we need to keep in mind wheher we're dealing with
the transcoder or the pipe, and a slightly higher level split makes
that easier.

We can simplify the icl check in intel_dsc_source_support()
by noting that the only case when DSC is not supported is when
using transcoder A.

Trying to do readout when we don't even have a cpu transcoder
is not a great idea. Don't do it.

Make use of the struct_size() helper instead of an open-coded version,
in order to avoid any potential type mistakes or integer overflows that,
in the worst scenario, could lead to heap overflows.
Also, address the following sparse warnings:
