Increasing ref counts of both dma-buf and gem for imported dma-buf come from gem
makes memory leak. release function of dma-buf cannot be called because f_count
of dma-buf increased by importing gem and gem ref count cannot be decrease
because of exported dma-buf.
So I add dma_buf_put() for imported gem come from its own gem into each drivers
having prime_import and prime_export capabilities. With this, only gem ref
count is increased if importing gem exported from gem of same driver.

Summary:
- change exynos file license
. Most of exynos files had been copied from some randome
file and not updated correctly(wrong company name used).
This was our mistakes so chagnes it correctly. For this,
I'm not sure that this patch should go to -fix or -next.
So please give me any comment if there is any problem.
- consider buffer allocation without iommu
. Without iommu, dma_alloc_attrs function allocates some
memory region and returns cpu address so this patch makes
the cpu address to be set to buf->kvaddr correctly
- cleanups to ipp relevant codes.
- use common finish page flip function
. to avoid the duplication of same code, use
exynos_drm_crtc_finish_pageflip function commonly instead
of each one.
- fix fimd resume issue.
. when fimd was turned off by suspend, there was one issue that
the fimd wasn't turned on by resume so fix it chaing resume
condition.
* 'exynos-drm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos: (25 commits)
drm/exynos: move finish page flip to a common place
drm/exynos: fimd: modify condition in fimd resume

The problem is that the wrong symbol was defined as the default value
for the choice. Using the correct value gets rid of the infinite loop.

vga-switcheroo with apple-gmux does not switch correctly on my system. The PCI
configuration space is not restored correctly, resulting in MSI not working after switch.
Only useful item in dmesg is:
[ 33.922807] radeon 0000:01:00.0: Refused to change power state, currently in D3
I did some testing, dumping the difference in ms between first succesful switch
from D3 to D0, and it seems that there is slightly more than 20 ms difference when
the device is re-enabled through vga-switcheroo.
So bump the re-enable d3 delay to 20 ms to handle this, which fixes msi not working
on my system after switcheroo-ing. Default d3_delay value is PCI_PM_D3_WAIT, 10 ms.

The use of writel instead of writel_relaxed lead to deadlock in some
situation (SMP on Armada 370 for instance). The use of writel_relaxed
as it was done in the rest of this driver fixes this bug.

This patch fixes a bug for Aurora L2 cache controller when the
write-through mode is enable. For the clean operation even if we don't
have to flush the lines we still need to invalidate them.

vortex_wt_setdsout performs bit-negation on the bit position (wt&0x1f)
rather than on the resulting bitmask. This code is never actually
invoked (vortex_wt_setdsout is always called with en=1), so this does
not currently cause any problem, and this patch is simply cleanup.

commit 35f9c09fe9 (tcp: tcp_sendpages() should call tcp_push() once)
added an internal flag : MSG_SENDPAGE_NOTLAST meant to be set on all
frags but the last one for a splice() call.
The condition used to set the flag in pipe_to_sendpage() relied on
splice() user passing the exact number of bytes present in the pipe,
or a smaller one.
But some programs pass an arbitrary high value, and the test fails.
The effect of this bug is a lack of tcp_push() at the end of a
splice(pipe -> socket) call, and possibly very slow or erratic TCP
sessions.
We should both test sd->total_len and fact that another fragment
is in the pipe (pipe->nrbufs > 1)
Many thanks to Willy for providing very clear bug report, bisection
and test programs.

If fimd is runtime suspended (by DPMS OFF), fimd_suspend does not
call fimd_activate(false) and just returns. Similarily the check in
fimd_resume should not resume if previously runtime_suspended.
Instead the existing check does the opposite. So if fimd was not
runtime suspended, suspend will turn off fimd but resume will not turn
it on. This patch fixes this issue by reversing the condition.

Commit "ext4: Remove CONFIG_EXT4_FS_XATTR" removed the configuration
dependencies for ext4 xattrs from the ext4 ACLs and security labels
configuration options, but did not replace them with a dependency on
ext4 itself. Add back the dependency on ext4 so the options only show
up if ext4 is enabled.

If CONFIG_ARCH_MULTIPLATFORM & CONFIG_ARCH_MVEBU are both enabled,
__v7_pj4b_setup is added between __v7_ca9mp_setup and __v7_setup.
But there's no jump instruction added. If the chip is Cortex A5/A9,
it goes through __v7_pj4b_setup also. It results in system hang.

Since commit 62e4d357a (ARM: 7609/1: disable errata work-arounds which access
secure registers) ARM_ERRATA_743622/751472 depends on !ARCH_MULTIPLATFORM.
Since imx has been converted to multiplatform, the following warning happens:
$ make imx_v6_v7_defconfig
warning: (SOC_IMX6Q && ARCH_TEGRA_2x_SOC && ARCH_TEGRA_3x_SOC) selects
ARM_ERRATA_751472 which has unmet direct dependencies (CPU_V7 &&
!ARCH_MULTIPLATFORM)

Recommended approach is to remove ARM_ERRATA_743622/751472 from being selected
by SOC_IMX6Q and apply such workarounds into the bootloader.
