6a6d73be12 KVM: arm/arm64: properly use vcpu requests 
arm/arm64 already has one VCPU request used when setting pause,
but it doesn't properly check requests in VCPU RUN. Check it
and also make sure we set vcpu->mode at the appropriate time
(before the check) and with the appropriate barriers. See
Documentation/virtual/kvm/vcpu-requests.rst. Also make sure we
don't leave any vcpu requests we don't intend to handle later
set in the request bitmap. If we don't clear them, then
kvm_request_pending() may return true when it shouldn't.

Using VCPU requests properly fixes a small race where pause
could get set just as a VCPU was entering guest mode.

2387149ead KVM: improve arch vcpu request defining 
Marc Zyngier suggested that we define the arch specific VCPU request
base, rather than requiring each arch to remember to start from 8.
That suggestion, along with Radim Krcmar's recent VCPU request flag
addition, snowballed into defining something of an arch VCPU request
defining API.

No functional change.

(Looks like x86 is running out of arch VCPU request bits.  Maybe
 someday we'll need to extend to 64.)

abd7229626 KVM: arm/arm64: Simplify active_change_prepare and plug race 
We don't need to stop a specific VCPU when changing the active state,
because private IRQs can only be modified by a running VCPU for the
VCPU itself and it is therefore already stopped.

However, it is also possible for two VCPUs to be modifying the active
state of SPIs at the same time, which can cause the thread being stuck
in the loop that checks other VCPU threads for a potentially very long
time, or to modify the active state of a running VCPU.  Fix this by
serializing all accesses to setting and clearing the active state of
interrupts using the KVM mutex.

d2e1936884 KVM: arm: Restore banked registers and physical timer access on hyp_panic() 
When KVM panics, it hurridly restores the host context and parachutes
into the host's panic() code. This looks like it was copied from arm64,
the 32bit KVM panic code needs to restore the host's banked registers
too.

At some point panic() touches the physical timer/counter, this will
trap back to HYP. If we're lucky, we panic again.

Add a __timer_save_state() call to KVMs hyp_panic() path, this saves the
guest registers and disables the traps for the host.

Fixes: c36b6db5f3 ("ARM: KVM: Add panic handling code")

791a9a666d Kbuild UAPI header export updates for v4.12 
Improvement of headers_install by Nicolas Dichtel.
 
 It has been long since the introduction of uapi directories,
 but the de-coupling of exported headers has not been completed.
 Headers listed in header-y are exported whether they exist in
 uapi directories or not.  His work fixes this inconsistency.
 
 All (and only) headers under uapi directories are now exported.
 The asm-generic wrappers are still exceptions, but this is a big
 step forward.

fcc8487d47 uapi: export all headers under uapi directories 
Regularly, when a new header is created in include/uapi/, the developer
forgets to add it in the corresponding Kbuild file. This error is usually
detected after the release is out.

In fact, all headers under uapi directories should be exported, thus it's
useless to have an exhaustive list.

After this patch, the following files, which were not exported, are now
exported (with make headers_install_all):

c81ee18e97 ARM: SoC defconfig updates 
We've traditionally kept defconfig updates in a separate branch, often to
 encourage submaintainers to handle those patches separately to avoid conflicts
 on the shared files. The amount of changes seem to be decreasing though, so
 we might rethink how we handle this going forward.
 
 There really isn't much to write about here. The bulk of changes here
 are enabling drivers for whatever platforms the hardware is found on

85d604902e ARM: Device-tree updates 
Device-tree continues to see lots of updates. The majority of patches
 here are smaller changes for new hardware on existing platforms, and
 there are a few larger changes worth pointing out.
 
 Major new platforms:
 
  - Gemini has been ported to DT, so a handful of "new" platforms moved over
    from board files
  - Rockchip RK3288 support for Tinkerboard and Phytec phyCORE-RK3288 SoM and RDK
  - A bunch of embedded platforms, several Linksys platforms, Synology DS116,
  - Motorola Droid4 (really old OMAP-based phone) support is added.
 
 Some refactorings, i.e. Allwinner H3/H5 support is commonalized.
 
 And lots of smaller changes, cleanups, etc. See shortlog for more description
 
 We're adding ability to cross-include DT files between arm and arm64,
 by creating appropriate links in the dt-include directory, and using arm/
 and arm64/ as include prefixes. This will avoid other local hacks such as
 per-file links between the two arch trees (this broke for external mirroring
 of DT contents). Now they can just provide their own appropriate dt-include
 hierarcy per platform.

Merge tag 'armsoc-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM Device-tree updates from Olof Johansson:
 "Device-tree continues to see lots of updates. The majority of patches
  here are smaller changes for new hardware on existing platforms, and
  there are a few larger changes worth pointing out.

  Major new platforms:

   - Gemini has been ported to DT, so a handful of "new" platforms moved
     over from board files

   - Rockchip RK3288 support for Tinkerboard and Phytec phyCORE-RK3288
     SoM and RDK

   - A bunch of embedded platforms, several Linksys platforms, Synology
     DS116,

   - Motorola Droid4 (really old OMAP-based phone) support is added.

  Some refactorings, i.e. Allwinner H3/H5 support is commonalized.

  And lots of smaller changes, cleanups, etc. See shortlog for more
  description

  We're adding ability to cross-include DT files between arm and arm64,
  by creating appropriate links in the dt-include directory, and using
  arm/ and arm64/ as include prefixes. This will avoid other local hacks
  such as per-file links between the two arch trees (this broke for
  external mirroring of DT contents). Now they can just provide their
  own appropriate dt-include hierarcy per platform"

063246641d format-security: move static strings to const 
While examining output from trial builds with -Wformat-security enabled,
many strings were found that should be defined as "const", or as a char
array instead of char pointer.  This makes some static analysis easier,
by producing fewer false positives.

As these are all trivial changes, it seemed best to put them all in a
single patch rather than chopping them up per maintainer.

299878bac3 treewide: move set_memory_* functions away from cacheflush.h 
Patch series "set_memory_* functions header refactor", v3.

The set_memory_* APIs came out of a desire to have a better way to
change memory attributes.  Many of these attributes were linked to cache
functionality so the prototypes were put in cacheflush.h.  These days,
the APIs have grown and have a much wider use than just cache APIs.  To
support this growth, split off set_memory_* and friends into a separate
header file to avoid growing cacheflush.h for APIs that have nothing to
do with caches.

35d2d5d490 KVM: arm/arm64: Move shared files to virt/kvm/arm 
For some time now we have been having a lot of shared functionality
between the arm and arm64 KVM support in arch/arm, which not only
required a horrible inter-arch reference from the Makefile in
arch/arm64/kvm, but also created confusion for newcomers to the code
base, as was recently seen on the mailing list.

Further, it causes confusion for things like cscope, which needs special
attention to index specific shared files for arm64 from the arm tree.

Move the shared files into virt/kvm/arm and move the trace points along
with it.  When moving the tracepoints we have to modify the way the vgic
creates definitions of the trace points, so we take the chance to
include the VGIC tracepoints in its very own special vgic trace.h file.

a90f0e9ebb regulator: Updates for v4.12 
Quite a lot going on with the regulator API for this release, much more
 in the core than in the drivers for a change:
 
  - Fixes for voltage change propagation through dumb power switches.
  - A notification when regulators are enabled.
  - A new settling time property for regulators where the time taken to
    move to a new voltage is not related to the size of the change.
  - Some reorganization of the Arizona drivers in preparation for sharing
    the code with the next generation devices they've been integrated
    with.
  - Support for newer Freescale chips in the Anatop regulator.
  - A new driver for voltage controlled regulators to cope with some
    exciting ChromeOS hardware designs.
  - Support for Rohm BD9571MWV-M and TI TPS65132.

 "Quite a lot going on with the regulator API for this release, much
  more in the core than in the drivers for a change:

   - Fixes for voltage change propagation through dumb power switches.

   - A notification when regulators are enabled.

   - A new settling time property for regulators where the time taken to
     move to a new voltage is not related to the size of the change.

   - Some reorganization of the Arizona drivers in preparation for
     sharing the code with the next generation devices they've been
     integrated with.

   - Support for newer Freescale chips in the Anatop regulator.

   - A new driver for voltage controlled regulators to cope with some
     exciting ChromeOS hardware designs.

   - Support for Rohm BD9571MWV-M and TI TPS65132"

Merge tag 'pinctrl-v4.12-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pin control updates from Linus Walleij:
 "This is the bulk of pin control changes for the v4.12 cycle.

  The extra week before the merge window actually resulted in some of
  the type of fixes that usually arrive after the merge window already
  starting to trickle in from eager developers using -next, I'm
  impressed.

  I have recruited a Samsung subsubsystem maintainer (Krzysztof) to deal
  with the onset of Samsung patches. It works great.

  Apart from that it is a boring round, just incremental updates and
  fixes all over the place, no serious core changes or anything exciting
  like that. The most pleasing to see is Julia Cartwrights work to audit
  the irqchip-providing drivers for realtime locking compliance. It's
  one of those "I should really get around to looking into that" things
  that have been on my TODO list since forever.

  Summary:

  Core changes:

   - add bi-directional and output-enable pin configurations to the
     generic bindings and generic pin controlling core.

  New drivers or subdrivers:

   - Armada 37xx SoC pin controller and GPIO support.

   - Axis ARTPEC-6 SoC pin controller support.

   - AllWinner A64 R_PIO controller support, and opening up the
     AllWinner sunxi driver for ARM64 use.

   - Rockchip RK3328 support.

   - Renesas R-Car H3 ES2.0 support.

   - STM32F469 support in the STM32 driver.

   - Aspeed G4 and G5 pin controller support.

   - switch meson driver to get the GPIO ranges from the device tree.

   - input schmitt trigger support on the Rockchip driver.

e371fd7607 xen: Implement EFI reset_system callback 
When rebooting DOM0 with ACPI on ARM64, the kernel is crashing with the stack
trace [1].

This is happening because when EFI runtimes are enabled, the reset code
(see machine_restart) will first try to use EFI restart method.

However, the EFI restart code is expecting the reset_system callback to
be always set. This is not the case for Xen and will lead to crash.

The EFI restart helper is used in multiple places and some of them don't
not have fallback (see machine_power_off). So implement reset_system
callback as a call to xen_reboot when using EFI Xen.

The x86 code has theoritically a similar issue, altought EFI does not
seem to be the preferred method. I have only built test it on x86.

This should also probably be fixed in stable tree.

    Changes in v2:
        - Implement xen_efi_reset_system using xen_reboot
        - Move xen_efi_reset_system in drivers/xen/efi.c

e058632670 xen/arm,arm64: fix xen_dma_ops after 815dd18 "Consolidate get_dma_ops..." 
The following commit:

  commit 815dd18788
  Author: Bart Van Assche <bart.vanassche@sandisk.com>
  Date:   Fri Jan 20 13:04:04 2017 -0800

      treewide: Consolidate get_dma_ops() implementations

rearranges get_dma_ops in a way that xen_dma_ops are not returned when
running on Xen anymore, dev->dma_ops is returned instead (see
arch/arm/include/asm/dma-mapping.h:get_arch_dma_ops and
include/linux/dma-mapping.h:get_dma_ops).

Fix the problem by storing dev->dma_ops in dev_archdata, and setting
dev->dma_ops to xen_dma_ops. This way, xen_dma_ops is returned naturally
by get_dma_ops. The Xen code can retrieve the original dev->dma_ops from
dev_archdata when needed. It also allows us to remove __generic_dma_ops
from common headers.
