KVM/ARM updates for v4.9-rc4

- Kick the vcpu when a pending interrupt becomes pending again
- Prevent access to invalid interrupt registers
- Invalid TLBs when two vcpus from the same VM share a CPU

94d0e5980d arm/arm64: KVM: Perform local TLB invalidation when multiplexing vcpus on a single CPU
Architecturally, TLBs are private to the (physical) CPU they're
associated with. But when multiple vcpus from the same VM are
being multiplexed on the same CPU, the TLBs are not private
to the vcpus (and are actually shared across the VMID).

Let's consider the following scenario:

- vcpu-0 maps PA to VA
- vcpu-1 maps PA' to VA

If run on the same physical CPU, vcpu-1 can hit TLB entries generated
by vcpu-0 accesses, and access the wrong physical page.

The solution to this is to keep a per-VM map of which vcpu ran last
on each given physical CPU, and invalidate local TLBs when switching
to a different vcpu from the same VM.

2674235fd4 ARM: SoC fixes
We haven't seen a whole lot of fixes for the first two weeks since the merge
 window, but here is the batch that we have at the moment.
 
 Nothing sticks out as particularly bad or scary, it's mostly a handful of
 smaller fixes to several platforms. The Uniphier reset controller changes
 could probably have been delayed to 4.10, but they're not scary and just
 plumbing up driver changes that went in during the merge window.
 
 We're also adding another maintainer to Marvell Berlin platforms, to help
 out when Sebastian is too busy. Yay teamwork!

44d524218c ARM: dts: vf610: fix IRQ flag of global timer
The global timer IRQ (PPI[0], PPI 11 in device tree terms) is a
rising edge interrupt. The ARM Cortex-A5 MPCore TRM in Chapter
10.1.2. Interrupt types and sources says:
"Interrupt is rising-edge sensitive."

The bits seem to be read-only, hence this missconfiguration had
no negative effect. However, with commit 992345a58e
("irqchip/gic: WARN if setting the interrupt type for a PPI fails")
warnings such as this get printed:
GIC: PPI11 is secure or misconfigured

With this change the new configuration matches the default
configuration and no warning is printed anymore.

Instead of returning of_genpd_add_provider_onecell() directly,
we should check its return value and in the case of error we
should unwind the previously taken actions, which in these case are:
- Call imx6q_pm_pu_power_off()
- Set imx6q_pu_domain.reg back to NULL

Setting imx6q_pu_domain.reg to NULL in the error case is important
as it will prevent further operations in the pu_reg regulator.

This kernel crash is not observed with imx_v6_v7_defconfig because
it selects GPU and VPU drivers, which are consumers of the GPC block
and thus change the refcount of the pu_reg regulator.

eef0b282bb ARM: imx: gpc: Initialize all power domains
Since commit 0159ec6707 ("PM / Domains: Verify the PM domain is present
when adding a provider") the following regression is observed on imx6:

imx-gpc: probe of 20dc000.gpc failed with error -22

The gpc probe fails because of_genpd_add_provider_onecell() now checks
if all the domains are initialized via pm_genpd_present() function
and it fails because not all the power domains are initialized.

In order to fix this error, initialize all the power domains from
imx_gpc_domains[], not only the imx6q_pu_domain.base one.

c8ea0395ff arm/arm64: KVM: Map the BSS at HYP
When used with a compiler that doesn't implement "asm goto"
(such as the AArch64 port of GCC 4.8), jump labels generate a
memory access to find out about the value of the key (instead
of just patching the code). The key itself is likely to be
stored in the BSS.

This is perfectly fine, except that we don't map the BSS at HYP,
leading to an exploding kernel at the first access. The obvious
fix is simply to map the BSS there (which should have been done
a long while ago, but hey...).

1b283eea62 ARM: dts: fix the SD card on the Snowball
This fixes a very annoying regression on the Snowball SD card
that has been around for a while. It turns out that the device
tree does not configure the direction pins properly, nor sets
up the pins for the voltage converter properly at boot. Unless
all things are correctly set up, the feedback clock will not
work, and makes the driver spew messages in the console (but
it works, very slowly):

root@Ux500:/ mount /dev/mmcblk0p2 /mnt/
[    9.953460] mmci-pl18x 80126000.sdi0_per1: error during DMA transfer!
[    9.960296] mmcblk0: error -110 sending status command, retrying
[    9.966461] mmcblk0: error -110 sending status command, retrying
[    9.972534] mmcblk0: error -110 sending status command, aborting

Fix this by rectifying the device tree to correspond to that of
the Ux500 HREF boards plus the DAT31DIR setting that is unique for
the Snowball, and things start working smoothly. Add in the SDR12
and SDR25 modes which this host can do without any problems.

I don't know if this has ever been correct, sadly. It works after
this patch.

Pull kbuild updates from Michal Marek:

 - EXPORT_SYMBOL for asm source by Al Viro.

   This does bring a regression, because genksyms no longer generates
   checksums for these symbols (CONFIG_MODVERSIONS). Nick Piggin is
   working on a patch to fix this.

   Plus, we are talking about functions like strcpy(), which rarely
   change prototypes.

 - Fixes for PPC fallout of the above by Stephen Rothwell and Nick
   Piggin

 - fixdep speedup by Alexey Dobriyan.

 - preparatory work by Nick Piggin to allow architectures to build with
   -ffunction-sections, -fdata-sections and --gc-sections

 - CONFIG_THIN_ARCHIVES support by Stephen Rothwell

 - fix for filenames with colons in the initramfs source by me.

 - Introduce hardware-tracked trip points support to the device tree
   thermal sensor framework. The framework supports an arbitrary number
   of trip points. Whenever the current temperature is changed, the trip
   points immediately below and above the current temperature are found,
   driver callback is invoked to program the hardware to get notified
   when either of the two trip points are triggered. Hardware-tracked
   trip points support for rockchip thermal driver is also added at the
   same time. From Sascha Hauer, Caesar Wang

Kernel source files need not include <linux/kconfig.h> explicitly

This commit removes explicit includes except the following:

  * tools/testing/radix-tree/linux/kernel.h

These two are used for host programs.

c984cbf2e3 ARM: use simpler API for random address requests
Currently, all callers to randomize_range() set the length to 0 and
calculate end by adding a constant to the start address.  We can simplify
the API to remove a bunch of needless checks and variables.

Use the new randomize_addr(start, range) call to set the requested
address.

c913fc4146 ARM: SoC: late DT updates for v4.9
These updates have been kept in a separate branch mostly because
 they rely on updates to the respective clk drivers to keep the
 shared header files in sync.
 
 - The Renesas r8a7796 (R-Car M3-W) platform gets added, this is an
   automotive SoC similar to the ⅹ8a7795 chip we already support, but
   the dts changes rely on a clock driver change that has been
   merged for v4.9 through the clk tree.
 
 - The Amlogic meson-gxbb (S905) platform gains support for a few
   drivers merged through our tree, in particular the network and
   usb driver changes are required and included here, and also
   the clk tree changes.
 
 - The Allwinner platforms have seen a large-scale change to their
   clk drivers and the dts file updates must come after that.
   This includes the newly added Nextthing GR8 platform, which is
   derived from sun5i/A13.
 
 - Some integrator (arm32) changes rely on clk driver changes.
 
 - A single patch for lpc32xx has no such dependency but wasn't
   added until just before the merge window

 enable devices in existing machines, or to fix minor bugs.  Notably,
 an ongoing treewide effort to fix warnings caused by an update to the

 but can hopefully become the default once all issues have been addressed.

66f2c6d952 ARM: SoC platform updates for v4.9
These are updates for platform specific code on 32-bit ARM machines,
 essentially anything that can not (yet) be expressed using DT files.
 
 Noteworthy changes include:
 
 - We get support for running in big-endian mode on two platforms:
   sunxi (Allwinner) and s3c24xx (old Samsung).
 
 - The recently added Uniphier platform now uses standard PSCI
   methods for SMP booting and we remove support for old bootloader
   versions that did not support it yet.
 
 - In sunxi, we gain support for the "Nextthing GR8" SoC, which
   is a close relative of the Allwinner A13 and R8 chips.
 
 - PXA completes its move over to the generic dmaengine framework
   and removes its old private API
 
 - mach-bcm gains support for BCM47189/BCM53573, their first ARM
   SoC with integrated 802.11ac wireless networking.

a771151a83 ARM: SoC cleanups for v4.9
The cleanups for v4.9 are a little larger that usual, but thankfully
 that is almost exclusively due to removing a significant number of
 files that have become obsolete after the still ongoing conversion
 of old board files to devicetree.
 
 - for mach-omap2, which is still the largest platform in arch/arm/,
   the conversion to DT is finally complete after the Nokia N900 is
   now fully supported there, along with the omap3 LDP, and we can
   remove those two board files.
   If no regressions are found, another large cleanup for the platform
   will happen as a follow-up, removing dead code and restructuring
   the platform based on being DT-only.
 
 - In mach-imx, similar work is ongoing, but has not come that far.
   This time, we remove the obsolete board file for the i.MX1
   generation, which like i.MX25, i.MX5, i.MX6, and i.MX7 is now DT-only.
   The remaining board files are for i.MX2 and i.MX3 machines
   based on old ARM926 or ARM1136 cores that should work with DT
   in principle.
 
 - realview has just been converted from board files to DT, and a lot
   of code gets removed in the process. This is the last
   ARM/Keil/Versatile derived platform that was still using board
   files, the other ones being integrator, versatile and vexpress.
   We can probably merge the remaining code into a single directory
   in the near future.
 
 - clps711x had completed the conversion in v4.8, but we accidentally
   left the files in place that should have been deleted then.
 
 Conflicts: two files deleted here have been modified upstream,
 the changes can be discarded.

6727ad9e20 nmi_backtrace: generate one-line reports for idle cpus
When doing an nmi backtrace of many cores, most of which are idle, the
output is a little overwhelming and very uninformative.  Suppress
messages for cpus that are idling when they are interrupted and just
emit one line, "NMI backtrace for N skipped: idling at pc 0xNNN".

We do this by grouping all the cpuidle code together into a new
.cpuidle.text section, and then checking the address of the interrupted
PC to see if it lies within that section.

This commit suitably tags x86 and tile idle routines, and only adds in
the minimal framework for other architectures.

6776648952 nmi_backtrace: do a local dump_stack() instead of a self-NMI
Currently on arm there is code that checks whether it should call
dump_stack() explicitly, to avoid trying to raise an NMI when the
current context is not preemptible by the backtrace IPI.  Similarly, the
forthcoming arch/tile support uses an IPI mechanism that does not
support generating an NMI to self.

Accordingly, move the code that guards this case into the generic
mechanism, and invoke it unconditionally whenever we want a backtrace of
the current cpu.  It seems plausible that in all cases, dump_stack()
will generate better information than generating a stack from the NMI
handler.  The register state will be missing, but that state is likely
not particularly helpful in any case.

Or, if we think it is helpful, we should be capturing and emitting the
current register state in all cases when regs == NULL is passed to
nmi_cpu_backtrace().

9a01c3ed5c nmi_backtrace: add more trigger_*_cpu_backtrace() methods
Patch series "improvements to the nmi_backtrace code" v9.

This patch series modifies the trigger_xxx_backtrace() NMI-based remote
backtracing code to make it more flexible, and makes a few small
improvements along the way.

The motivation comes from the task isolation code, where there are
scenarios where we want to be able to diagnose a case where some cpu is
about to interrupt a task-isolated cpu.  It can be helpful to see both
where the interrupting cpu is, and also an approximation of where the
cpu that is being interrupted is.  The nmi_backtrace framework allows us
to discover the stack of the interrupted cpu.

I've tested that the change works as desired on tile, and build-tested
x86, arm, mips, and sparc64.  For x86 I confirmed that the generic
cpuidle stuff as well as the architecture-specific routines are in the
new cpuidle section.  For arm, mips, and sparc I just build-tested it
and made sure the generic cpuidle routines were in the new cpuidle
section, but I didn't attempt to figure out which the platform-specific
idle routines might be.  That might be more usefully done by someone
with platform experience in follow-up patches.

This patch (of 4):

Currently you can only request a backtrace of either all cpus, or all
cpus but yourself.  It can also be helpful to request a remote backtrace
of a single cpu, and since we want that, the logical extension is to
support a cpumask as the underlying primitive.

This change modifies the existing lib/nmi_backtrace.c code to take a
cpumask as its basic primitive, and modifies the linux/nmi.h code to use
the new "cpumask" method instead.

The existing clients of nmi_backtrace (arm and x86) are converted to
using the new cpumask approach in this change.

The other users of the backtracing API (sparc64 and mips) are converted
to use the cpumask approach rather than the all/allbutself approach.
The mips code ignored the "include_self" boolean but with this change it
will now also dump a local backtrace if requested.

51a021244b atomic64: no need for CONFIG_ARCH_HAS_ATOMIC64_DEC_IF_POSITIVE
This came to light when implementing native 64-bit atomics for ARCv2.

The atomic64 self-test code uses CONFIG_ARCH_HAS_ATOMIC64_DEC_IF_POSITIVE
to check whether atomic64_dec_if_positive() is available.  It seems it
was needed when not every arch defined it.  However as of current code
the Kconfig option seems needless

 - for CONFIG_GENERIC_ATOMIC64 it is auto-enabled in lib/Kconfig and a
   generic definition of API is present lib/atomic64.c
 - arches with native 64-bit atomics select it in arch/*/Kconfig and
   define the API in their headers

So I see no point in keeping the Kconfig option

Compile tested for:
 - blackfin (CONFIG_GENERIC_ATOMIC64)
 - x86 (!CONFIG_GENERIC_ATOMIC64)
 - ia64

  - Error reporting: we have added a new mechanism for users of dmaenegine to
    register a callback_result which tells them the result of the dma
    transaction. Right now only one user ntb is using it.
  - As we discussed on KS mailing list and pointed out NO_IRQ has no place in
    kernel, this also remove NO_IRQ from dmaengine subsystem (both arm and
    ppc users)
  - Support for IOMMU slave transfers and it implementation for arm.
  - To get better build coverage, enable COMPILE_TEST for bunch of driver,
    and fix the warning and sparse complaints on these.
  - Apart from above, usual updates spread across drivers.

Pull dmaengine updates from Vinod Koul:
 "This is bit large pile of code which bring in some nice additions:

   - Error reporting: we have added a new mechanism for users of
     dmaenegine to register a callback_result which tells them the
     result of the dma transaction. Right now only one user (ntb) is
     using it.

   - As we discussed on KS mailing list and pointed out NO_IRQ has no
     place in kernel, this also remove NO_IRQ from dmaengine subsystem
     (both arm and ppc users)

   - Support for IOMMU slave transfers and its implementation for arm.

   - To get better build coverage, enable COMPILE_TEST for bunch of
     driver, and fix the warning and sparse complaints on these.

   - Apart from above, usual updates spread across drivers"

Pull ARM updates from Russell King:

 - Correct ARMs dma-mapping to use the correct printk format strings.

 - Avoid defining OBJCOPYFLAGS globally which upsets lkdtm rodata
   testing.

 - Cleanups to ARMs asm/memory.h include.

 - L2 cache cleanups.

 - Allow flat nommu binaries to be executed on ARM MMU systems.

 - Kernel hardening - add more read-only after init annotations,
   including making some kernel vdso variables const.

 - Ensure AMBA primecell clocks are appropriately defaulted.

 - ARM breakpoint cleanup.

 - Various StrongARM 11x0 and companion chip (SA1111) updates to bring
   this legacy platform to use more modern APIs for (eg) GPIOs and
   interrupts, which will allow us in the future to reduce some of the
   board-level driver clutter and elimate function callbacks into board
   code via platform data. There still appears to be interest in these
   platforms!

 - Remove the now redundant secure_flush_area() API.

 - Module PLT relocation optimisations. Ard says: This series of 4
   patches optimizes the ARM PLT generation code that is invoked at
   module load time, to get rid of the O(n^2) algorithm that results in
   pathological load times of 10 seconds or more for large modules on
   certain STB platforms.

 - ARMv7M cache maintanence support.

 - L2 cache PMU support

fb833b1fbb ARM: fix delays
Commit 215e362daf ("ARM: 8306/1: loop_udelay: remove bogomips value
limitation") tried to increase the bogomips limitation, but in doing
so messed up udelay such that it always gives about a 5% error in the
delay, even if we use a timer.

The calculation is:

	loops = UDELAY_MULT * us_delay * ticks_per_jiffy >> UDELAY_SHIFT

Originally, UDELAY_MULT was ((UL(2199023) * HZ) >> 11) and UDELAY_SHIFT
30.  Assuming HZ=100, us_delay of 1000 and ticks_per_jiffy of 1660000
(eg, 166MHz timer, 1ms delay) this would calculate:

	((UL(2199023) * HZ) >> 11) * 1000 * 1660000 >> 30
		=> 165999

With the new values of 2047 * HZ + 483648 * HZ / 1000000 and 31, we get:

	(2047 * HZ + 483648 * HZ / 1000000) * 1000 * 1660000 >> 31
		=> 158269

which is incorrect.  This is due to a typo - correcting it gives:

	(2147 * HZ + 483648 * HZ / 1000000) * 1000 * 1660000 >> 31
		=> 165999

i.o.w, the original value.
