Add a mutex into struct i915_address_space to be used while operating on
the vma and their lists for a particular vm. As this may be called from
the shrinker, we taint the mutex with fs_reclaim so that from the start
lockdep warns us if we are caught holding the mutex across an
allocation. (With such small steps we will eventually rid ourselves of
struct_mutex recursion!)

getrawmonotonic64() and get_monotonic_boottime64() are deprecated
because of the nonstandard naming.
The replacement functions ktime_get_raw_ns() and ktime_get_boot_ns()
also simplify the callers.

it's exactly the same thing as
dentry_open(&file->f_path, file->f_flags, file->f_cred)
... and rename it to file_clone_open(), while we are at it.
'filp' naming convention is bogus; sure, it's "file pointer",
but we generally don't do that kind of Hungarian notation.
Some of the instances have too many callers to touch, but this
one has only two, so let's sanitize it while we can...

Problem: When PD/PT update made by CPU root PD was not yet mapped causing
page fault.
Fix: Verify root PD is mapped into CPU address space.
v2:
Make sure that we add the root PD to the relocated list
since then it's get mapped into CPU address space bt default
in amdgpu_vm_update_directories.
v3:
Drop change to not move kernel type BOs to evicted list.
v4:

This reverts commit 018d82e5f0.
This breaks DDC in certain cases. Revert for 4.18 and previous kernels.
For 4.19, this is fixed with the following more extensive patches:
drm/amd/display: Serialize is_dp_sink_present
drm/amd/display: Break out function to simply read aux reply
drm/amd/display: Return aux replies directly to DRM
drm/amd/display: Right shift AUX reply value sooner than later
drm/amd/display: Read AUX channel even if only status byte is returned

A call to ttm_bo_unref() clears the supplied pointer to NULL, while
ttm_bo_put() does not. None of the converted call sites requires the
pointer to become NULL, so the respective assign operations has been
left out from the patch.

The TTM buffer-object interface provides ttm_bo_reference() and
ttm_bo_unref() for managing reference counts. Replacing them with
ttm_bo_get() and ttm_bo_put() aligns the API with conventions used
throughout the Linux kernel.
The implementation of ttm_bo_unref() clears the supplied pointer
to NULL. This leads to workarounds where the caller saves the
pointer's value before de-referencing the BO. ttm_bo_put() does
not clear the supplied pointer.

Refactor Innolux P079ZCA panel driver, let it support multi panels from
Innolux that share similar power sequences.
Panels may require different power supplies so use regulator bulk
interfaces and define per panel supply-names.
Changes in v2:
- Change regulator property name to meet the panel datasheet
Changes in v3:
- this patch only refactor P079ZCA panel to support multi panel,
support P097PFG panel in another patch
Changes in v4:
- Modify the patch which suggest by Thierry
Changes in v5:
- use regulator_bulk to handle different supply number
