Fixup some fallout of the fallout of atomic dpms, few mdp5 cursor
fixes, fix a leak in error path, and some fixes for kexec

* 'msm-fixes-4.0' of git://people.freedesktop.org/~robclark/linux:
  drm/msm: kexec fixes
  drm/msm/mdp5: fix cursor blending
  drm/msm/mdp5: fix cursor ROI
  drm/msm/atomic: Don't leak atomic commit object when commit fails
  drm/msm/mdp5: Avoid flushing registers when CRTC is disabled
  drm/msm: update generated headers (add 6th lm.base entry)
  drm/msm/mdp5: fixup "drm/msm: fix fallout of atomic dpms changes"

In kexec environment, we are more likely to encounter irq's already
enabled from previous environment.  At which point we find that writes
to disable/clear pending irq's are slightly less than useless without
first enabling clocks.

TODO: full blown state read-in so kexec'd kernel can inherit the mode
already setup.

Seems like we just want BLEND_EN and not BLEND_TRANSP_EN (setting the
latter results in black pixels in the cursor image treated as
transparent).

If cursor is set near the edge of the screen, it is not valid to use the

If the atomic commit fails due to completion wait interruption the
atomic commit object is not freed and is thus leaked. Free it.

When a CRTC is disabled, no CTL is allocated to it (CRTC->ctl == NULL);
in that case we should not try to FLUSH registers and do nothing instead.

This can happen when we try to move a cursor but the CRTC's CTL
(CONTROL) has not been allocated yet (inactive CRTC).
It can also happens when we .atomic_check()/.atomic_flush() on a
disabled CRTC.

A CTL needs to be kept as long as the CRTC is alive. Releasing it
after the last VBlank is safer than in .atomic_flush().

Commit 0b776d45 ("drm/msm: fix fallout of atomic dpms
changes") has a typo in both mdp5_encoder_helper_funcs and
mdp5_crtc_helper_funcs definitions:

	.dpms entry should be replaced by .disable and .enable

Also fixed a typo in mdp5_encoder_enable().

Note that these typos are only present for MDP5. MDP4 is fine.

We need to store device offsets in 64 bit as the device
address space may be larger than the CPU's.

Fixes GPU init failures on radeons with 4GB or more of
vram on 32 bit kernels.  We put vram at the start of the
GPU's address space so the gart aperture starts at 4 GB
causing all GPU addresses in the gart aperture to get
truncated.

The current implementation is limited by the number of addresses that
fit into an unsigned long. This causes problems on 32-bit Tegra where
unsigned long is 32-bit but drm_mm is used to manage an IOVA space of
4 GiB. Given the 32-bit limitation, the range is limited to 4 GiB - 1
(or 4 GiB - 4 KiB for page granularity).

This commit changes the start and size of the range to be an unsigned
64-bit integer, thus allowing much larger ranges to be supported.
