To workaround a HW bug on DG2, driver is required to map the whole
ppgtt virtual address space before GPU workload submission. Thus
set the XE_VM_FLAG_SCRATCH_PAGE flag during vm create so the whole
address space is mapped to point to scratch page.
v1:
- Move the workaround implementation from xe_vm_create to
xe_vm_create_ioctl - Brian
- Reorder error checking in xe_vm_create_ioctl - Jose
- Implement WA only for DG2-G10 and DG2-G12

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
