  drm/radeon: drop ttm two ended allocation

Merge branch 'exynos-drm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-fixes

   Some urgent regression fixes to booting failures Exynos DRM occured.

   Summary:
   - Fix two urgent null pointer dereference bugs in case of enabling
     or disabling IOMMU. There was two cases to these issues.
     One is that plane->crtc is accessed by exynos_disable_plane()
     when device tree binding is broken so device driver tries
     to release, which means that the mode set operation isn't invoked yet
     so plane->crtc is still NULL and exynos_disable_plane() will access
     NULL pointer. This issue is fixed by checking if the plane->crtc
     is NULL or not in exynos_disable_plane()

     Other is that fimd_wait_for_vblank() is called to avoid from page fault
     with IOMMU before the ctx object is created. At this time,
     fimd_wait_for_vblank() tries to access ctx->crtc but the ctx->crtc
     is still NULL because exynos_drm_crtc_create() isn't called yet.
     This issue is fixed by creating a crtc object and setting it to
     ctx->crtc prior to fimd_wait_for_vblank() call.

     For more details, you can refer to below an e-mail thread,
     http://www.spinics.net/lists/linux-samsung-soc/msg42436.html

   - Remove unnecessary file not used and fix trivial issues.

* 'exynos-drm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos:
  drm/exynos: fix the initialization order in FIMD
  drm/exynos: fix typo config name correctly.
  drm/exynos: Check for NULL dereference of crtc
  drm/exynos: IS_ERR() vs NULL bug
  drm/exynos: remove unused files

radeon_bo_create() calls radeon_ttm_placement_from_domain()
before ttm_bo_init() is called.  radeon_ttm_placement_from_domain()
uses the ttm bo size to determine when to select top down
allocation but since the ttm bo is not initialized yet the
check is always false.  It only took effect when buffers
were validated later.  It also seemed to regress suspend
and resume on some systems possibly due to it not
taking effect in radeon_bo_create().

radeon_bo_create() and radeon_ttm_placement_from_domain()
need to be reworked substantially for this to be optimally
effective.  Re-enable it at that point.

Since commit 0f04cf8d ("drm/exynos:
fix wrong pipe calculation for crtc"), fimd_clear_channel() can be
called when is_drm_iommu_supported() returns true. In this case,
the kernel is going to be panicked because crtc is not set yet.

The commit "drm/exynos: remove exynos_plane_dpms" (d9ea6256) removed the
use of the enabled flag, which means that the code may attempt to call
win_enable on a NULL crtc. This results in the following oops on

Complete bong hit (and not the last...), the hardware will reassert the
interrupt to PMC if it's necessary.

Also potentially harmful in the face of interrupts such as the non-stall
interrupt, which remain active in NV_PFIFO_INTR even when we don't care
about servicing it.

It appears (hopefully, fdo#87244), that under certain loads, the methods
may pass quickly enough to hit the "100 spins and kill PFIFO" thing that
we had going on.  Not ideal ;)

This patch fixes the SDMA queue initialization, when running in non-HWS mode.

The first fix is to move the initialization of SDMA VM parameters before the
initialization of the SDMA MQD.

The second fix is to load the MQD to an HQD after the initialization of the MQD.

 "The clk fixes for 4.0-rc4 comprise three themes.

  First are the usual driver fixes for new regressions since v3.19.

  Second are fixes to the common clock divider type caused by recent
  changes to how we round clock rates.  This affects many clock drivers
  that use this common code.

  Finally there are fixes for drivers that improperly compared struct
  clk pointers (drivers must not deref these pointers).  While some of
  these drivers have done this for a long time, this did not cause a
  problem until we started generating unique struct clk pointers for
  every consumer.  A new function, clk_is_match was introduced to get
  these drivers working again and they are fixed up to no longer deref
  the pointers themselves"

The ARM architecture allows the caching of intermediate page table
levels and page table freeing requires a sequence like:

	pmd_clear()
	TLB invalidation
	pte page freeing

With commit 5e5f6dc1 (arm64: mm: enable HAVE_RCU_TABLE_FREE logic),
the page table freeing batching was moved from tlb_remove_page() to
tlb_remove_table(). The former takes care of TLB invalidation as this is
also shared with pte clearing and page cache page freeing. The latter,
however, does not invalidate the TLBs for intermediate page table levels
as it probably relies on the architecture code to do it if required.
When the mm->mm_users < 2, tlb_remove_table() does not do any batching
and page table pages are freed before tlb_finish_mmu() which performs
the actual TLB invalidation.

This patch introduces __tlb_flush_pgtable() for arm64 and calls it from
the {pte,pmd,pud}_free_tlb() directly without relying on deferred page
table freeing.
