Because CRAT_CU_FLAGS_IOMMU_PRESENT was not set in some BIOS crat, we
need to workaround this.
For future compatibility, we also overwrite the bit in capability according
to the value of needs_iommu_device.

CWSR fails on Raven if the control stack is MTYPE_UC, which is used
for regular GART mappings. As a workaround we map it using MTYPE_NC.
The MEC firmware expects the control stack at one page offset from the
start of the MQD so it is part of the MQD allocation on GFXv9. AMDGPU
added a memory allocation flag just for this purpose.

For some reason I thought GPIOLIB handles translation from GPIO ranges
to pinctrl pins but it turns out not to be the case. This means that
when GPIOs operations are performed for a pin controller having a custom
GPIO base such as Cannon Lake and Ice Lake incorrect pin number gets
used internally.
Fix this in the same way we did for lock/unlock IRQ operations and
translate the GPIO number to pin before using it.
Fixes: a60eac3239f0 ("pinctrl: intel: Allow custom GPIO base for pad groups")

The final field of a floppy_struct is the field "name", which is a pointer
to a string in kernel memory. The kernel pointer should not be copied to
user memory. The FDGETPRM ioctl copies a floppy_struct to user memory,
including this "name" field. This pointer cannot be used by the user
and it will leak a kernel address to user-space, which will reveal the
location of kernel code and data and undermine KASLR protection.
Model this code after the compat ioctl which copies the returned data
to a previously cleared temporary structure on the stack (excluding the
name pointer) and copy out to userspace from there. As we already have
an inparam union with an appropriate member and that memory is already
cleared even for read only calls make use of that as a temporary store.
Based on an initial patch by Brian Belleville.

hen we're comparing the hardware completion mask passed in from the
driver with the internal tag pending mask, we need to account for the
fact that the internal tag is different from the hardware tag. If not,
then we can end up either prematurely completing the internal tag (since
it's not set in the hw mask), or simply flag an error:
ata2: illegal qc_active transition (100000000->00000001)
If the internal tag is set, then swap that with the hardware tag in this
case before comparing with what the hardware reports.
Fixes: 28361c403683 ("libata: add extra internal command")

Planes without an alpha property, using __drm_atomic_helper_plane_reset
will have their plane state alpha initialised as zero, which represents
a transparent alpha.
If this value is then used for the plane, it may not be visible by
default, and thus doesn't represent a good initialisation state.
Update the default state->alpha value to DRM_BLEND_ALPHA_OPAQUE
unconditionally when the plane is reset.

Stolen memory is lost across S4 (hibernate) or S3-RST as it is a portion
of ordinary volatile RAM. As we allocate our rings from stolen, this may
include the rings used for our preempt context and their breadcrumb
instructions. In order to allow preemption following hibernation and
loss of stolen memory, we therefore need to repopulate the instructions
inside the lost ring upon resume. To handle both module load and resume,
we simply defer constructing the ring to first use.
