commit 07678eca2cf9c9a18584e546c2b2a0d0c9a3150c upstream.
When vmw_gb_surface_define_ioctl() is called with an existing buffer,
we end up returning an uninitialized variable in the backup_handle.
The fix is to first initialize backup_handle to 0 just to be sure, and
second, when a user-provided buffer is found, we will use the
req->buffer_handle as the backup_handle.

commit ee9c4e681ec4f58e42a83cb0c22a0289ade1aacf upstream.
The 'req->mip_levels' parameter in vmw_gb_surface_define_ioctl() is
a user-controlled 'uint32_t' value which is used as a loop count limit.
This can lead to a kernel lockup and DoS. Add check for 'req->mip_levels'.

When calling smmu mapping, if iova is specified directly by user, not
allocated dynamically in dma-mapping.c, smmu driver needs to provide
support for this. This is needed in early display case. In this scenario,
LK has set physical memory to display hardware for fetching, so if iova
is not explicitly specified in kernel, but instead dynamically produced
by "alloc_iova" in dma-mapping.c, display hardware has no chance to know
this new iova, then smmu fault will happen if enabling the iommu stage-1
translation.
To fix this smmu fault problem, add re-routing to the right path when
iova specified by user is not 0 in smmu map function.

Currently the priority and other behavior of a command stream
is provided by the user application during submission and
the application is expected to internally maintain the settings
for each 'context' or 'rendering queue' and specify the correct
ones.
This works okay for simple cases but as applications become more
complex we will want to set context specific flags and do various
permisson checks to allow certain contexts to enable additional
privileges.
Add kernel-side submit queues to be analogous to 'contexts' or
'rendering queues' on the application side. Each file descriptor
instance will maintain its own list of queues. Queues cannot be
shared between file descriptors.
For backwards compatibility context id '0' is defined as a default
context specifying middle priority and no special flags. This is
intended to be the usual configuration for 99% of applications so
that a garden variety application can function correctly without
creating a queue. Only those applications requiring the specific
benefit of different queues need create one.
In addition to the basic infrastructure, allow the user to specify
the queue priority - this will be used in lieu of the legacy
flags to set priority during the submission. Only the master DRM
instance can set the highest priority, but all the others are open
to all processes.
