981302783e ARM/...: timer and clock events cleanup, and remove struct sys_timer
This branch contains a number of cleanups and unifications to various
 timer- clock-events- and ARM timer code. The main points are:
 
 1) Convert arch_gettimeoffset to a pointer, so that architectures with
    multiple timer implementations can simply set this standard pointer
    rather than maintaining their own arch-specific pointers for the
    same purpose. Various architectures are converted to using this new
    feature.
 
 2) Conversion of ARM timer implementations to use clock_event_devices's
    suspend/resume operations, rather than the ARM-specific sys_timer
    versions. Thus, the ARM code begins to use more common infra-structure
    rather than arch-specific code.
 
 3) Removal of ARM's struct sys_timer completely, now that everything uses
    common code.
 
 4) Introduction of drivers/clocksource/clksrc-of.c, which allows ARM clock
    source implementations to be moved into drivers/clocksource, with the
    need to add SoC-specific header files for each timer initialization
    function; instead, all enabled implementations are registered into a
    table which a single core function iterates over, and calls the
    relevant initialization functions based on device tree. At least the
    Tegra and BCM2835 clocksource implementations will use this feature in
    the 3.9 kernel cycle.

e8e89622ed drm/ttm: fix fence locking in ttm_buffer_object_transfer
Noticed while reviewing the fence locking in the radeon pageflip
handler.

v2: Instead of grabbing the bdev->fence_lock in object_transfer just
move the single callsite of that function a few lines, so that it is
protected by the fence_lock. Suggested by Jerome Glisse.

0b3455a71e ARM: highbank: fix secondary boot and hotplug
With commit 384a290 (ARM: gic: use a private mapping for CPU target
interfaces), wake-up IPIs now go to all cores as the gic cpu interface
numbering may not follow core numbering. This broke secondary boot on
highbank since the boot address was already set for all secondary cores,
this caused all cores to boot before the kernel was ready.

Fix this by moving the setting of the jump address to
highbank_boot_secondary instead of highbank_smp_prepare_cpus and
highbank_cpu_die. Also, clear the address when we boot. This prevents
cores from booting before they are actually triggered and is also necessary
to get suspend/resume to work.

be8a42ae60 drm/prime: drop reference on imported dma-buf come from gem
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.

f3215be950 Merge branch 'exynos-drm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next
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)

6adba67eb0 ARM: OMAP2+: am33xx-hwmod: Fix wrongly terminated am33xx_usbss_mpu_irqs array
The IRQ array must be terminated by -1 and not by -1+OMAP_INTC_START
This led to having a resource list of 100s of IRQs.

Looks like this was caused by commit a2cfc509 (ARM: OMAP3+: hwmod: Add

36a25de233 sctp: fix Kconfig bug in default cookie hmac selection
Commit 0d0863b020 ("sctp: Change defaults on cookie hmac selection")
added a "choice" to the sctp Kconfig file.  It introduced a bug which
led to an infinite loop when while running "make oldconfig".

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.

Note:  if CONFIG_SCTP_COOKIE_HMAC_SHA1=y was present in the input
config file, both that and CONFIG_SCTP_COOKIE_HMAC_MD5=y be present
in the generated config file.

After f65aad41772f("MIPS: Cavium: Add EDAC support."), when entering

EDAC appeared merged with the rest of the device drivers types. This was
because the menuconfig option EDAC is querying an EDAC_SUPPORT Kconfig

When pushing EDAC_SUPPORT up, before the menu definition, the variable
is defined earlier and the above menuconfig artifact doesn't happen.

d1f9809ed1 drm/radeon: add quirk for d3 delay during switcheroo poweron for apple macbooks
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.

ae62ca7b03 tcp: fix MSG_SENDPAGE_NOTLAST logic
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.

Instead the existing check does the opposite. So if fimd was not

d106de38ca ARM: 7614/1: mm: fix wrong branch from Cortex-A9 to PJ4b
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.

a47e3bc10d ARM: 7612/1: imx: Do not select some errata that depends on !ARCH_MULTIPLATFORM
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)
warning: (SOC_IMX6Q && ARCH_TEGRA_3x_SOC) selects ARM_ERRATA_743622
which has unmet direct dependencies (CPU_V7 && !ARCH_MULTIPLATFORM)
warning: (SOC_IMX6Q && ARCH_TEGRA_3x_SOC) selects ARM_ERRATA_743622
which has unmet direct dependencies (CPU_V7 && !ARCH_MULTIPLATFORM)
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.

dab9206445 dma: mv_xor: fix error handling for clocks
When a channel fails to initialize, we release all ressources,
including clocks. However, a XOR unit is not necessarily associated to
a clock (some variants of Marvell SoCs have a clock for XOR units,
some don't), so we shouldn't unconditionally be releasing the clock.

Instead, just like we do in the mv_xor_remove() function, we should
check if one clock was found before releasing it.
