fdb68e09bb drm: Zero out invalid vblank timestamp in drm_update_vblank_count.
Since commit 844b03f277 we make
sure that after vblank irq off, we return the last valid
(vblank count, vblank timestamp) pair to clients, e.g., during
modesets, which is good.

An overlooked side effect of that commit for kms drivers without
support for precise vblank timestamping is that at vblank irq
enable, when we update the vblank counter from the hw counter, we
can't update the corresponding vblank timestamp, so now we have a
totally mismatched timestamp for the new count to confuse clients.

Restore old client visible behaviour from before Linux 3.17, but
zero out the timestamp at vblank counter update (instead of disable
as in original implementation) if we can't generate a meaningful
timestamp immediately for the new vblank counter. This will fix
this regression, so callers know they need to retry again later
if they need a valid timestamp, but at the same time preserves
the improvements made in the commit mentioned above.

8f59ae0643 ARM: SoC fixes for 4.1-rc2
A few patches have come up since the merge window. The largest one is a
 rewrite of the PXA lubbock/mainstone IRQ handling. This was already
 broken in 2011 by a change to the GPIO code and only noticed now.
 
 The other changes contained here are:
 
 MAINTAINERS file updates:
 - Ray Jui and Scott Branden are now co-maintainers for some of the
   mach-bcm chips, while Christian Daudt and Marc Carino have stepped
   down.
 - Andrew Victor is no longer maintaining at91. Instead, Alexandre
   Belloni now becomes an official maintainer, after having done a
   bulk of the work for a while.
 - Baruch Siach, who added the mach-digicolor platform in 4.1
   is now listed as maintainer
 - The git URL for mach-socfpga has changed
 
 Bug fixes:
 - Three bug fixes for new rockchip rk3288 code
 - A regression fix to make SD card support work on certain ux500
   boards
 - multiple smaller dts fixes for imx, omap, mvebu, and shmobile
 - a regression fiix for omap3 power consumption
 - a fix for regression in the ARM CCI bus driver
 
 Configuration changes:
 - more imx platforms are now enabled in multi_v7_defconfig

8cf5e6dc8d ARM: dts: Add keep-power-in-suspend to WiFi SDIO node for exynos5250-snow
The Marvell mwifiex driver prevents the system to enter into a suspend
state if the card power is not preserved during a suspend/resume cycle.

So Suspend-to-RAM and Suspend-to-idle are failing on Exynos5250 Snow.

Add the keep-power-in-suspend Power Management property to the SDIO/MMC
node so the mwifiex suspend handler doesn't fail and the system is able
to enter into a suspend state.

0d74776296 ARM: dts: Make DP a consumer of DISP1 power domain on Exynos5420
Commit ea08de16eb ("ARM: dts: Add DISP1 power domain for exynos5420")
added a device node for the Exynos5420 DISP1 power domain but dit not
make the DP controller a consumer of that power domain.

This causes an "Unhandled fault: imprecise external abort" error if the
exynos-dp driver tries to access the DP controller registers and the PD
was turned off. This lead to a kernel panic and a complete system hang.

Make the DP controller device node a consumer of the DISP1 power domain
to ensure that the PD is turned on when the exynos-dp driver is probed.

3790e395b8 drm/tegra: Don't use vblank_disable_immediate on incapable driver.
Tegra would not only need a hardware vblank counter that
increments at leading edge of vblank, but also support
for instantaneous high precision vblank timestamp queries, ie.
a proper implementation of dev->driver->get_vblank_timestamp().

Without these, there can be off-by-one errors during vblank
disable/enable if the scanout is inside vblank at en/disable
time, and additionally clients will never see any useable
vblank timestamps when querying via drmWaitVblank ioctl. This
would negatively affect swap scheduling under X11 and Wayland.

b9a5e5e18f ACPI / init: Fix the ordering of acpi_reserve_resources()
Since acpi_reserve_resources() is defined as a device_initcall(),
there's no guarantee that it will be executed in the right order
with respect to the rest of the ACPI initialization code.  On some
systems this leads to breakage if, for example, the address range
that should be reserved for the ACPI fixed registers is given to
the PCI host bridge instead if the race is won by the wrong code
path.

Fix this by turning acpi_reserve_resources() into a void function
and calling it directly from within the ACPI initialization sequence.

the used_mask array size is based on CCI_PMU_MAX_HW_EVENTS.
CCI_PMU_MAX_HW_EVENTS is not based on NR_CPUS, so CPU_BITS_NONE
is not correct and will cause a build failure if NR_CPUS
is set high enough to make CPU_BITS_NONE larger than used_mask.

These fixes reenable the lubbock(pxa25x) and mainstone(pxa27x)
 platforms, which were broken since the gpio handling was
 converted to a driver, and the interrupt ordering broke the
 external interrupts of these systems.

d6bcc8069b Two fixes from Chris Zhong, fixing some suspend oddities.
And I've given up on the timer7 issue. While I initially thought
 devices would either have both the grave mmu issue requiring a uboot
 update and the timer7 issue or none, it looks like in all units in the
 field the mmu issue got fixed while the timer7 issue stayed on.
 So instead of making everybody wanting to use mainline jump through a
 hoop just make sure timer7 is on on boot before we init the arch-timer.
