These two patches fix a problem with the madvise purging code for the
shmem helpers where the mmaping for a purged buffer wouldn't get
invalidated correctly. This presumably ends up as a security hole
where the mapping can be accessed from user-space to read and write
random pages from other buffer
When a buffer is madvised as not needed and then purged, any attempts to
access the buffer from user-space should cause a bus fault. This patch
adds a check for that.

When mmapping the shmem, it would previously adjust the pgoff in the
vm_area_struct to remove the fake offset that is added to be able to
identify the buffer. This patch removes the adjustment and makes the
fault handler use the vm_fault address to calculate the page offset
instead. Although using

Hi,
this patch set adds the support of the Lontium lt8912 MIPI to HDMI
bridge in the kernel.
It's only support the video part, not the audio part yet
since I don't have the datasheet of this component.
I get the current i2c configuration from Digi and
Boundary drivers.
Developed using the DB_DSIHD

The recent commit 6c63e6e14da7 ("drm/i915/hdcp: No HDCP when encoder
is't initialized") added a null pointer check on connector->encoder
hence implying that it could potentially be null. This means that
the initialization of dig_port via the call intel_attached_dig_port

By having selected DRM_XEN, I was assuming I would build the frontend
driver. As it turns out this is a dummy option, and I have really not
been building this (because I had DRM disabled). Make it a promptless
one, moving the "depends on" to the other, real option, and "select"ing
the dummy one.

Update the mediatek,dpi binding to use the graph schema. Missed
this one from the mass conversion since it's not part of drm-misc.

Something that didn't get noticed until I started running cursor tests:
we're accidentally disabling an option for CRC calculation that's enabled
by default: WidePipeCrc, which controls whether we use the full width of
the data in the display pipe in order calculate CRCs. Having this disabled

If BO is validated again into non-system domain, say, VRAM domain. It
actually should not be in the swap list.

Currently the FSC SYNC_BIT and MOD_SYNC_BIT are toggled

Currently, for WLED5, after FSC register update MOD_SYNC_BIT
is toggled instead of SYNC_BIT. MOD_SYNC_BIT has to be toggled
after the brightness update and SYNC_BIT has to be toggled after
FSC update for WLED5. Fix it.
