git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC fixes from Arnd Bergmann:
"This is the first set of bugfixes for ARM SoCs, fixing a couple of
stability problems, mostly on TI OMAP and Rockchips platforms:
- OMAP2 hwmod clocks must be enabled in the correct order
- OMAP3 Wakeup from resume through PRM IRQ was unreliable
- one regression on OMAP5 caused by a kexec fix
- Rockchip ethernet needs some settings for stable operation on
Rock64
- Rockchip based Chrombook Plus needs another clock setting for
stable display suspend/resume
- Rockchip based phyCORE-RK3288 was able to run at an invalid CPU
clock frequency
- Rockchip MMC link was sometimes unreliable
- multiple fixes to avoid crashes in the Broadcom STB DPFE driver
Other minor changes include:
- Devicetree fixes for incorrect hardware description (rockchip,
omap, Gemini, amlogic)
- some MAINTAINER file updates to correct email and git addresses
- some fixes addressing 'make W=1' dtc warnings (broadcom, amlogic,
cavium, qualcomm, hisilicon, zx)
- fixes for LTO-compilation (orion, davinci, clps711x)
- one fix for an incorrect Kconfig errata selection
- a memory leak in the OMAP timer driver
- a kernel data leak in OMAP1 debugfs files"

On CPU hotunplug the enqueued timers of the unplugged CPU are migrated to a
live CPU. This happens from the control thread which initiated the unplug.
If the CPU on which the control thread runs came out from a longer idle
period then the base clock of that CPU might be stale because the control
thread runs prior to any event which forwards the clock.
In such a case the timers from the unplugged CPU are queued on the live CPU
based on the stale clock which can cause large delays due to increased
granularity of the outer timer wheels which are far away from base:;clock.
But there is a worse problem than that. The following sequence of events
illustrates it:
- CPU0 timer1 is queued expires = 59969 and base->clk = 59131.
The timer is queued at wheel level 2, with resulting expiry time = 60032
(due to level granularity).
- CPU1 enters idle @60007, with next timer expiry @60020.
- CPU0 is hotplugged at @60009
- CPU1 exits idle and runs the control thread which migrates the
timers from CPU0
timer1 is now queued in level 0 for immediate handling in the next
softirq because the requested expiry time 59969 is before CPU1 base->clk
60007
- CPU1 runs code which forwards the base clock which succeeds because the
next expiring timer. which was collected at idle entry time is still set
to 60020.
So it forwards beyond 60007 and therefore misses to expire the migrated
timer1. That timer gets expired when the wheel wraps around again, which
takes between 63 and 630ms depending on the HZ setting.
Address both problems by invoking forward_timer_base() for the control CPUs
timer base. All other places, which might run into a similar problem
(mod_timer()/add_timer_on()) already invoke forward_timer_base() to avoid
that.

Localize link rate arrays by moving them to the functions where they're
used. Further clarify the distinction between source and sink
capabilities. Split pre and post Haswell arrays, and get rid of the
array size arithmetics. Use a direct rate value in the paranoia case of
no common rates find.

When using CPU to update page table, we need to kmap all the PDs/PTs after
they are allocated and that requires a TLB shot down on each CPU, which is
quite heavy.
Instead, we map the whole visible VRAM to a kernel address at once. Pages
can be obtained from the offset.

The drm layer expects aux->transfer() to return the payload bytes read.
Currently dm_dp_aux_transfer() returns the payload size which does not
gets updated during the read, hence not giving the right data for the
drm layer to pars edid. This leads to the drm layer to conclude as the
edid is BAD and hence some monitors/devices dont get detected properly.
This patch changes the return type of dm_dp_aux_transfer() to actual
bytes read during DP_AUX_NATIVE_READ & DP_AUX_I2C_READ.

A toolstack may delete the vif frontend and backend xenstore entries
while xen-netfront is in the removal code path. In that case, the
checks for xenbus_read_driver_state would return XenbusStateUnknown, and
xennet_remove would hang indefinitely. This hang prevents system
shutdown.
xennet_remove must be able to handle XenbusStateUnknown, and

Current cleanup in the error path of xen_bind_pirq_msi_to_irq is
wrong. First of all there's an off-by-one in the cleanup loop, which
can lead to unbinding wrong IRQs.
Secondly IRQs not bound won't be freed, thus leaking IRQ numbers.
Note that there's no need to differentiate between bound and unbound
IRQs when freeing them, __unbind_from_irq will deal with both of them
correctly.

Commit fe49789fab97 ("drm/i915: Deconstruct execute fence") re-arranged
the code and moved the i915_gem_request_execute tracepoint to before the
global seqno is assigned to the request.
We need to move the tracepoint a bit later so this information is once
again available.

If we fail to unbind the vma (due to a signal on an active buffer that
needs to be moved for the next execbuf), then we need to clear the
persistent tracking state we setup for this execbuf.
Fixes: c7c6e46f913b ("drm/i915: Convert execbuf to use struct-of-array packing for critical fields")
