Again to align with the usual prefix of just drm_connector_. Again
done with sed + manual fixup for indent issues.

The vmalloc() function has no 2-factor argument form, so multiplication
factors need to be wrapped in array_size(). This patch replaces cases of:
vmalloc(a * b)
with:
vmalloc(array_size(a, b))
as well as handling cases of:
vmalloc(a * b * c)
with:
vmalloc(array3_size(a, b, c))
This does, however, attempt to ignore constant size factors like:
vmalloc(4 * 1024)
though any constants defined via macros get caught up in the conversion.
Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.
The Coccinelle script used for this was:

The kmalloc() function has a 2-factor argument form, kmalloc_array(). This
patch replaces cases of:
kmalloc(a * b, gfp)
with:
kmalloc_array(a * b, gfp)
as well as handling cases of:
kmalloc(a * b * c, gfp)
with:
kmalloc(array3_size(a, b, c), gfp)
as it's slightly less ugly than:
kmalloc_array(array_size(a, b), c, gfp)
This does, however, attempt to ignore constant size factors like:
kmalloc(4 * 1024, gfp)
though any constants defined via macros get caught up in the conversion.
Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.
The tools/ directory was manually excluded, since it has its own
implementation of kmalloc().

"qxl_bo_unref" may sleep, but calling "qxl_release_map" causes
"preempt_disable()" to be called and "preempt_enable()" isn't called
until "qxl_release_unmap" is used. Move the call to "qxl_bo_unref" out
from in between the two to avoid sleeping from an atomic context.
This issue can be demonstrated on a kernel with CONFIG_LOCKDEP=y by
creating a VM using QXL, using a desktop environment using Xorg, then
moving the cursor on or off a window.

Use new return type vm_fault_t for fault handler. For
now, this is just documenting that the function returns
a VM_FAULT value rather than an errno. Once all instances
are converted, vm_fault_t will become a distinct type.

The encoder callbacks are only called in case the video mode changes.
So any layout changes without mode changes will go unnoticed.
Add qxl_crtc_update_monitors_config(), based on the old

enable, disable and flush atomic crtc callbacks. Remove monitors_config

QXL associates mouse state with its primary plane.
Destroying a primary plane and putting a new one in place has the side
effect of destroying the cursor as well.
This commit changes the driver to reapply the cursor any time a new
primary is created. It achieves this by keeping a reference to the
cursor bo on the qxl_crtc struct.
This fix is very similar to
commit 4532b241a4b7 ("drm/qxl: reapply cursor after SetCrtc calls")
which got implicitly reverted as part of implementing the atomic
modeset feature.

Simply mmap'ing /dev/dri/card0 repeatedly will spam the kernel
log with qxl_mmap information messages. The following example code
illustrates this:
int main(void)
{
int fd = open("/dev/dri/card0", O_RDONLY);
if (fd == -1)
err(1, "open failed");
for (;;) {
void *m = mmap(NULL, 4096, PROT_READ,
MAP_SHARED, fd, 0);
if (m != MAP_FAILED)
munmap(m, 4096);
}
}
Stop the spamming by removing the pr_info message. Since the mmap'ing
returns -EINVAL there is no need for the pr_info message.

This patch changes the way the primary surface is used for dumb
framebuffers. Instead of configuring the bo itself as primary surface
a shadow bo is created and used instead. Framebuffers can share the
shadow bo in case they have the same format and resolution.
On atomic plane updates we don't have to update the primary surface in
case we pageflip from one framebuffer to another framebuffer which
shares the same shadow. This in turn avoids the flicker caused by the
primary-destroy + primary-create cycle, which is very annonying when
running wayland on qxl.
The qxl driver never actually writes to the shadow bo. It sends qxl
blit commands which update it though, and the spice server might
actually execute them (and thereby write to the shadow) in case the
local rendering is kicked for some reason. This happens for example in
case qemu is asked to write out a dump of the guest display (screendump
monitor command).

The atomic conversion of the qxl driver didn't got the primary surface
handling completely right. It works in the common simple cases, but
fails for example when changing the display resolution using xrandr or
in multihead setups.
The rules are simple: There is one primary surface. Before defining a
new one you have to destroy the old one.
This patch makes qxl_primary_atomic_update() destroy the primary surface
before defining a new one. It fixes is_primary flag updates. It adds
is_primary checks so we don't try to update the primary surface in case
it already has the state we want it being in.

This is the plumbing for supporting fb modifiers on planes. Modifiers
have already been introduced to some extent, but this series will extend
this to allow querying modifiers per plane. Based on this, the client to

supported modifiers upon initializing the plane.

- FBINFO_CAN_FORCE_OUTPUT has been a lie ever since we nerfed&removed
the entire panic handling code in our fbdev emulation. We might
restore kms panic output, but not through the bazillion of legacy
code layers called fbdev/fbcon, there's just no way to make that
work safely.
- With the module check change FBINFO_DEFAULT is always 0, so can be
removed too.
That removes another change to cargo-cult stuff in kms drivers, yay!

The old state is useful for drivers that need to perform operations at

While at it, rename the operation to .atomic_enable() to be consistent
