When upstream ioctl helper is created it will try to create small
allocation, adding I915_GEM_CREATE_EXT_SET_PAT extension. If it
succeeds, for all resources with valid pat index value it will then
explicitly program pat index value with gem create ext call.
PrintBOCreateDestroyResult value can be used to:
- print whether the set pat extension is supported by the kernel, when
ioctl helper is created
- print whether set pat extension was added for a given gem create ext
call and what pat index value was programmed
Note: introduced changes are disabled by defualt.
Toggle DisableGemCreateExtSetPat can be used to enable new functionality.

The memadvise with preferred location for kmd-migrated shared allocation
is set to device associated with cmd list by default to migrate data
to lmem on non-atomic gpu page fault as well (for performance reasons).

This change makes that drm file is opened in nonblocking mode for prelim
kernels. In such case when calling exec buffer ioctl and get
EAGAIN (aka EWOULDBLOCK) we may return error to API level
