Russell King f6ac49ba29 ARM: vexpress: fix CPU hotplug with CT9x4 tile.
The Cortex A9 tile fails to unplug CPUs if errata 643719 is not enabled.
This leads to random weird behaviours, but ultimately seem to lock the
kernel one way or another when a CPU is hot unplugged.

Symptoms range from a spinlock lockup in the scheduler, the entire
system hanging, to dumping out the kernel printk buffer a few lines at
a time, and other weird behaviours.

This is caused by the outgoing CPU not having its inner caches properly
flushed before it exits coherency - flush_cache_louis() is used to
achieve this, but as a result of the hardware bug, this function ends
up doing nothing without the errata workaround enabled.

As the Versatile Express has an affected CPU, this errata must always
be enabled.

Alexandre Belloni a18d0699dd ARM: at91/pm: move the standby functions to pm.c
The standby functions are now only used in pm.c, move them there.

Also, they are not inlined as a pointer to those functions is passed to the
cpuidle driver.

Alexandre Belloni 176a1b3dad ARM: at91: fix pm_suspend.S compilation when ARMv6 is selected
When compiling for multiplatform for both ARMv6 and ARMv7, the default compiler
flags are for ARMv6, and results in:

arch/arm/mach-at91/pm_suspend.S:144: Error: selected processor does not support ARM mode `dsb'

Enforce ARMv7 flags for pm_suspend.o when CPU_V7 is selected.

After 57a38effa5 (net: phy: micrel: disable broadcast for KSZ8081/KSZ8091)
the macb1 interface refuses to work properly because it tries
to cling to address 0 which isn't able to communicate in broadcast with
the mac anymore. The micrel phy on the board is actually configured
to show up at address 1.
Adding the phy node and its real address fixes the issue.

Olof Johansson efc98f7762 ARM: tegra: Device tree changes for v4.1-rc1
A bunch of changes to improve support on the Nyan Big (Acer Chromebook
 13). These enable the trackpad and make the WiFi card work. Changes to
 the userspace-exposed name of the soundcard are required for a better
 audio experience.
 
 Support for Nyan Blaze (HP Chromebook 14) is added. It is very similar
 to Nyan Big and therefore can enjoys many of the above improvements.
 
 Since the EMC driver can now be used to scale the frequency at which
 external memory is clocked, corresponding EMC frequency tables are added
 for Jetson TK1 and the Nyan boards.
 
 The Jetson TK1, Beaver and Nyan boards now also use generated pinmux
 data, which makes it easier to keep it in sync with the data provided by
 syseng.

Merge "arm-cci PMU updates for 4.1" from Will Deacon:

CCI-400 PMU updates

This series reworks some of the CCI-400 PMU code so that it can be used
on both ARM and ARM64-based systems, without the need to boot in secure
mode on the latter. This paves the way for CCI-500 support in future.

* tag 'arm-perf-4.1' of git://git.kernel.org/pub/scm/linux/kernel/git/will/linux:
  arm-cci: Fix CCI PMU event validation
  arm-cci: Split the code for PMU vs driver support
  arm-cci: Get rid of secure transactions for PMU driver
  arm-cci: Abstract the CCI400 PMU specific definitions
  arm-cci: Rearrange code for splitting PMU vs driver code
  drivers: cci: reject groups spanning multiple HW PMUs

 - Add device-tree support to the wlcore (wl12xx/wl18xx) driver.
 
 - Update the current users to use the bindings instead of pdata-quirks.
 
 - Finally, remove the deprecated wl12xx_platform_data struct
 
 Note that da850 board file code that still uses the platform data,
 but we have da850.dtsi that can be used instead. So it was decided
 that we should try to remove the wl12xx support from the da850
 board file as suggested by Sekhar Nori <nsekhar@ti.com>. As it's
 the last patch in the series, the last patch can be simply reverted
 if needed.
 
 As this series touches quite a bit of arch code, it was suggested
 by Kalle Valo <kvalo@codeaurora.org> that the whole series should
 be merged via the arm-soc tree.

Nicolas Pitre d3a875444a ARM: MCPM: move the algorithmic complexity to the core code
All backends are reimplementing a variation of the same CPU reference
count handling. They are also responsible for driving the MCPM special
low-level locking. This is needless duplication, involving algorithmic
requirements that are not necessarily obvious to the uninitiated.
And from past code review experience, those were all initially
implemented badly.

After 3 years, it is time to refactor as much common code to the core
MCPM facility to make the backends as simple as possible.  To avoid a
flag day, the new scheme is introduced in parallel to the existing
backend interface.  When all backends are converted over, the
compatibility interface could be removed.

The new MCPM backend interface implements simpler methods addressing
very platform specific tasks performed under lock protection while
keeping the algorithmic complexity and race avoidance local to the
core code.

We want to get omap3 moved over to device tree only based booting.
 
 These three board-*.c files seem to be inactive, so let's attempt
 to drop them now rather than later. With these dropped, we have
 omap3 device tree conversion status in a known state. Then we know
 that we have .dts support for the remaining omap3 board-*.c files,
 or it's being worked on.
 
 By dropping these files now, we can simply revert them if really
 needed for the next few merge cycles if we run into suprises.
 Reverting things later on will not be so easily done.

Make omap3isp configuration data structures more suitable for consumption by
the DT by separating the I2C bus information of all the sub-devices in a
group and the ISP bus information from each other. The ISP bus information
is made a pointer instead of being directly embedded in the struct.

In the case of the DT only the sensor specific information on the ISP bus
configuration is retained. The structs are renamed to reflect that.

After this change the structs needed to describe device configuration can be
allocated and accessed separately without those needed only in the case of
platform data. The platform data related structs can be later removed once
the support for platform data can be removed.

Geert Uytterhoeven fee3fd4fd2 ARM: 8338/1: kexec: Relax SMP validation to improve DT compatibility
When trying to kexec into a new kernel on a platform where multiple CPU
cores are present, but no SMP bringup code is available yet, the
kexec_load system call fails with:

    kexec_load failed: Invalid argument

The SMP test added to machine_kexec_prepare() in commit 2103f6cba6
("ARM: 7807/1: kexec: validate CPU hotplug support") wants to prohibit
kexec on SMP platforms where it cannot disable secondary CPUs.
However, this test is too strict: if the secondary CPUs couldn't be
enabled in the first place, there's no need to disable them later at
kexec time.  Hence skip the test in the absence of SMP bringup code.

This allows to add all CPU cores to the DTS from the beginning, without
having to implement SMP bringup first, improving DT compatibility.

IOMMU should be able to use single pages as well as bigger blocks, so if
higher order allocations fail, we should not affect state of the system,
with events such as OOM killer, but rather fall back to order 0
allocations.

This patch changes the behavior of ARM IOMMU DMA allocator to use
__GFP_NORETRY, which bypasses OOM invocation, for orders higher than
zero and, only if that fails, fall back to normal order 0 allocation
which might invoke OOM killer.

Russell King 767bf7e7a1 ARM: fix broken hibernation
Normally, when a CPU wants to clear a cache line to zero in the external
L2 cache, it would generate bus cycles to write each word as it would do
with any other data access.

However, a Cortex A9 connected to a L2C-310 has a specific feature where
the CPU can detect this operation, and signal that it wants to zero an
entire cache line.  This feature, known as Full Line of Zeros (FLZ),
involves a non-standard AXI signalling mechanism which only the L2C-310
can properly interpret.

There are separate enable bits in both the L2C-310 and the Cortex A9 -
the L2C-310 needs to be enabled and have the FLZ enable bit set in the
auxiliary control register before the Cortex A9 has this feature
enabled.

Unfortunately, the suspend code was not respecting this - it's not
obvious from the code:

swsusp_arch_suspend()
 cpu_suspend() /* saves the Cortex A9 auxiliary control register */
  arch_save_image()
  soft_restart() /* turns off FLZ in Cortex A9, and disables L2C */
   cpu_resume() /* restores the Cortex A9 registers, inc auxcr */

At this point, we end up with the L2C disabled, but the Cortex A9 with
FLZ enabled - which means any memset() or zeroing of a full cache line
will fail to take effect.

A similar issue exists in the resume path, but it's slightly more
complex:

swsusp_arch_suspend()
 cpu_suspend() /* saves the Cortex A9 auxiliary control register */
  arch_save_image() /* image with A9 auxcr saved */
...
swsusp_arch_resume()
 call_with_stack()
  arch_restore_image() /* restores image with A9 auxcr saved above */
  soft_restart() /* turns off FLZ in Cortex A9, and disables L2C */
   cpu_resume() /* restores the Cortex A9 registers, inc auxcr */

Again, here we end up with the L2C disabled, but Cortex A9 FLZ enabled.

There's no need to turn off the L2C in either of these two paths; there
are benefits from not doing so - for example, the page copies will be
faster with the L2C enabled.

Hence, fix this by providing a variant of soft_restart() which can be
used without turning the L2 cache controller off, and use it in both
of these paths to keep the L2C enabled across the respective resume
transitions.

Kuninori Morimoto e7199d3260 ARM: configs: remove all CONFIG_RCAR_AUDMAC_PP from ARM defconfigs
Renesas R-Car sound (= rsnd) needs 2 DMAC which are called as
Audio DMAC (= 1st DMAC) and Audio DMAC peri peri (2nd DMAC).
And rsnd had assumed that 1st / 2nd DMACs are implemented as DMAEngine.
But, in result of DMA ML discussion, 2nd DMAC was concluded that it is
not a general purpose DMAC (2nd DMAC is for Device to Device inside
sound system). Additionally, current DMAEngine can't support Device to
Device, and we don't have correct DT bindings for it at this point.
So the easiest solution for it is that move it from DMAEngine to rsnd
driver.
Audio DMAC peri peri DMAEngine is no longer needed.
Remove all CONFIG_RCAR_AUDMAC_PP from ARM defconfigs

Thomas Gleixner 7270d11c56 arm/bL_switcher: Kill tick suspend hackery
Use the new tick_suspend/resume_local() and get rid of the
homebrewn implementation of these in the ARM bL switcher.  The
check for the cpumask is completely pointless.  There is no harm
to suspend a per cpu tick device unconditionally.  If that's a
real issue then we fix it proper at the core level and not with
some completely undocumented hacks in some random core code.

Move the tick internals to the core code, now that this nuisance
is gone.

Andre Przywara 950324ab81 KVM: arm/arm64: rework MMIO abort handling to use KVM MMIO bus
Currently we have struct kvm_exit_mmio for encapsulating MMIO abort
data to be passed on from syndrome decoding all the way down to the
VGIC register handlers. Now as we switch the MMIO handling to be
routed through the KVM MMIO bus, it does not make sense anymore to
use that structure already from the beginning. So we keep the data in
local variables until we put them into the kvm_io_bus framework.
Then we fill kvm_exit_mmio in the VGIC only, making it a VGIC private
structure. On that way we replace the data buffer in that structure
with a pointer pointing to a single location in a local variable, so
we get rid of some copying on the way.
With all of the virtual GIC emulation code now being registered with
the kvm_io_bus, we can remove all of the old MMIO handling code and
its dispatching functionality.

I didn't bother to rename kvm_exit_mmio (to vgic_mmio or something),
because that touches a lot of code lines without any good reason.

This is based on an original patch by Nikolay.
