Peter Zijlstra 2e3ca7f6ea locking/mutex: Disable optimistic spinning on some architectures
commit 4badad352a upstream.

The optimistic spin code assumes regular stores and cmpxchg() play nice;
this is found to not be true for at least: parisc, sparc32, tile32,
metag-lock1, arc-!llsc and hexagon.

There is further wreckage, but this in particular seemed easy to
trigger, so blacklist this.

Opt in for known good archs.

Linus Torvalds 4d7eaa12f3 Merge branch 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm
Pull ARM fixes from Russell King:
 "A number of ARM updates for -rc, covering mostly ARM specific code,
  but with one change to modpost.c to allow Thumb section mismatches to
  be detected.

  ARM changes include reporting when an attempt is made to boot a LPAE
  kernel on hardware which does not support LPAE, rather than just being
  silent about it.

  A number of other minor fixes are included too"

Russell King 006fa2599b ARM: fix noMMU kallsyms symbol filtering
With noMMU, CONFIG_PAGE_OFFSET was not being set correctly.  As there's
no MMU, PAGE_OFFSET should be equal to PHYS_OFFSET in all cases.  This
commit makes that explicit.

Since we do this, we don't need to mess around in asm/memory.h with
ifdefs to sort this out, so let's get rid of that, and there's no point
offering the "Memory split" option for noMMU as that's meaningless
there.

Ian Campbell e17b2f114c xen: swiotlb: handle sizeof(dma_addr_t) != sizeof(phys_addr_t)
The use of phys_to_machine and machine_to_phys in the phys<=>bus conversions
causes us to lose the top bits of the DMA address if the size of a DMA address is not the same as the size of the phyiscal address.

This can happen in practice on ARM where foreign pages can be above 4GB even
though the local kernel does not have LPAE page tables enabled (which is
totally reasonable if the guest does not itself have >4GB of RAM). In this
case the kernel still maps the foreign pages at a phys addr below 4G (as it
must) but the resulting DMA address (returned by the grant map operation) is
much higher.

This is analogous to a hardware device which has its view of RAM mapped up
high for some reason.

This patch makes I/O to foreign pages (specifically blkif) work on 32-bit ARM
systems with more than 4GB of RAM.

Linus Torvalds 0ba3307a8e ARM: driver updates for 3.14
Updates of SoC-near drivers and other driver updates that makes more sense to
 take through our tree.
 
 The largest part of this is a conversion of device registration for some
 renesas shmobile/sh devices over to use resources. This has required
 coordination with the corresponding arch/sh changes, and we've agreed
 to merge the arch/sh changes through our tree.
 
 Added in this branch is support for Trusted Foundations secure firmware,
 which is what is used on many of the commercial Nvidia Tegra products
 that are in the market, including the Nvidia Shield. The code is local
 to arch/arm at this time since it's uncertain whether it will be shared
 with arm64 longer-term, if needed we will refactor later.
 
 A couple of new RTC drivers used on ARM boards, merged through our tree
 on request by the RTC maintainer.
 
 ... plus a bunch of smaller updates across the board, gpio conversions
 for davinci, etc.

Linus Torvalds f2c73464d7 ARM: SoC cleanups for 3.14
This is the branch where we usually queue up cleanup efforts, moving
 drivers out of the architecture directory, header file restructuring,
 etc. Sometimes they tangle with new development so it's hard to keep it
 strictly to cleanups.
 
 Some of the things included in this branch are:
 
 * Atmel SAMA5 conversion to common clock
 * Reset framework conversion for tegra platforms
  - Some of this depends on tegra clock driver reworks that are shared with Mike
    Turquette's clk tree.
 * Tegra DMA refactoring, which are shared branches with the DMA tree.
 * Removal of some header files on exynos to prepare for multiplatform

Linus Torvalds d4371f94bc sound updates for 3.14-rc1
It was holiday season, so no wonder that there are little changes in
 framework level, although diffstat shows quite many changes spreaded
 over sound/* directories.  Most of changes are cleanups, code
 refactoring and fixes.
 
 Some highlights:
 
 - Removal of OSS sleep_on usages by Arnd
 
 - Simplified memalloc helper codes, drop obsoleted features;
   now it's built into PCM driver instead of an individual module
 
 - Warn if PCM buffer preallocation fails, which will show page
   allocation issues more clearly
 
 - Compress offload API updates for sample rates by Vinod
 
 - PCM glitch workaround on ctxfi emu20k1 by Sarah
 
 - Drop cs46xx DSP blobs, using firmware loader now
 
 - USB-audio quitks for Plantronics Gamecom 780, Creative VF0420,
   and Focusrite Saffire 6
 
 HD-audio specifics:
 
 - Standardize Kconfigs of HD-audio codec drivers;
   now "make localmodconfig" recognizes configs properly (finally!)
 
 - Parallel PM implementation by Mengdong
 
 - BayleyBay/ValleyView2 board fixups
 
 - Broadwell audio support
 
 - Runtime PM improvement (PantherPoint, etc)
 
 - Quirks: Dell subwooer, Gigabyte mobo jack detection oddity,
   Dell AiO click noise fixes, Dell headset mic fixes, etc
 
 - Automatic bind with HDMI codec parser without generic parser
 
 - More AD codec fixes (since 3.12 regression) including the automatic
   stereo mix support
 
 - Common Thinkpad ACPI helper for Realtek and Conexant codecs
 
 ASoC specifics:
 
 - Update to the generic DMA code to support deferred probe and managed
   resources
 
 - New drivers for BCM2835 (used in Raspberry Pi), Tegra with MAX98090
   and Analog Devices AXI I2S and S/PDIF controller IPs
 
 - Device tree support for the simple card, max98090 and cs42l52
 
 - Conversion of the Samsung drivers to native dmaengine, making them
   multiplatform compatible and hopefully helping keep them more modern
   and up to date.
 
 - More regmap conversions, including a very welcome one for twl6040
   from Peter Ujfalusi
 
 - A big overhaul of the DaVinci drivers also from Peter Ujfalusi
 
 - Lots of DMA updates from Lars-Peter
 
 - Improvements to the constraints handling code from Lars-Peter
 
 - A very helpful conversion of the TWL4030 driver to regmap from Peter

Linus Torvalds 8e50966072 GPIO tree bulk changes for v3.14
A big set this merge window, as we have much going on in
 this subsystem. Major changes this time:
 
 - Some core improvements and cleanups to the new GPIO
   descriptor API. This seems to be working now so we can
   start the exodus to this API, moving gradually away from
   the global GPIO numberspace.
 
 - Incremental improvements to the ACPI GPIO core, and move
   the few GPIO ACPI clients we have to the GPIO descriptor
   API right *now* before we go any further. We actually
   managed to contain this *before* we started to litter
   the kernel with yet another hackish global numberspace for
   the ACPI GPIOs, which is a big win.
 
 - The RFkill GPIO driver and all platforms using it have
   been migrated to use the GPIO descriptors rather than
   fixed number assignments. Tegra machine has been migrated
   as part of this.
 
 - New drivers for MOXA ART, Xtensa GPIO32 and SMSC SCH311x.
   Those should be really good examples of how I expect a
   nice GPIO driver to look these days.
 
 - Do away with custom GPIO implementations on a major
   part of the ARM machines: ks8695, lpc32xx, mv78xx0.
   Make a first step towards the same in the horribly
   convoluted Samsung S3C include forest. We expect to
   continue to clean this up as we move forward.
 
 - Flag GPIO lines used for IRQ on adnp, bcm-kona, em,
   intel-mid and lynxpoint.
   This makes the GPIOlib core aware that a certain GPIO line
   is used for IRQs and can then enforce some semantics such
   as disallowing a GPIO line marked as in use for IRQ to be
   switched to output mode.
 
 - Drop all use of irq_set_chip_and_handler_name().
   The name provided in these cases were just unhelpful
   tags like "mux" or "demux".
 
 - Extend the MCP23s08 driver to handle interrupts.
 
 - Minor incremental improvements for rcar, lynxpoint, em
   74x164 and msm drivers.
 
 - Some non-urgent bug fixes here and there, duplicate
   #includes and that usual kind of cleanups.

This is because it's possible to have ZBOOT_ROM enabled, but at the
same time have another option enabled which selects AUTO_ZRELADDR
overriding the !ZBOOT_ROM dependency.  Fix this by reversing the
dependencies between ZBOOT_ROM and the options which depend on

The DT based MSM platforms can join the multi-platform builds, so
introduce a DT based ARCH_MSM option. This option allows DT based
MSM platforms to be built into the multi-platform kernel. Also
introduce a hidden ARCH_MSM config that both the DT and non-DT
platform support code select to avoid churn in places that depend
on CONFIG_ARCH_MSM.

With commit 11ec50caed ("word-at-a-time: provide generic big-endian

provides a zero_bytemask implementation, allowing us to make use of
DCACHE_WORD_ACCESS on big-endian CPUs, providing our
load_unaligned_zeropad function is endianness-clean.

This patch reworks the load_unaligned_zeropad fixup code to work for
both big- and little-endian CPUs, then removes the !CPU_BIG_ENDIAN check
when selecting DCACHE_WORD_ACCESS.

Linus Walleij 41c3548e6d ARM: s3c64xx: get rid of custom <mach/gpio.h>
This isolates the custom S3C64xx GPIO definition table to
<linux/platform_data/gpio-samsung-s3x64xx.h> as this is
used in a few different places in the kernel, removing the
need to depend on the implicit inclusion of <mach/gpio.h>
from <linux/gpio.h> and thus getting rid of a few nasty
cross-dependencies.

Also delete the CONFIG_SAMSUNG_GPIO_EXTRA stuff. Instead
roof the number of GPIOs for this platform:
First sum up all the GPIO banks from A to Q: 187 GPIOs.
Add the 16 "board GPIOs" and the roof for SAMSUNG_GPIO_EXTRA,
128, so in total maximum 187+16+128 = 331 GPIOs, so let's
take the same roof as for S3C24XX: 512. This way we can do
away with the GPIO calculation macros for GPIO_BOARD_START,
BOARD_NR_GPIOS and the definition of ARCH_NR_GPIOS.

need to depend on the implicit inclusion of <mach/gpio.h>
from <linux/gpio.h> and thus getting rid of a few nasty
cross-dependencies.

We also delete the nifty CONFIG_S3C24XX_GPIO_EXTRA stuff.
The biggest this can ever be for the S3C24XX is
CONFIG_S3C24XX_GPIO_EXTRA = 128, and then for CPU_S3C2443 or
CPU_S3C2416 32*12 GPIOs are added, so 32*12+128 = 512
is the absolute roof value on this platform. So we set
the size of ARCH_NR_GPIO to this and the GPIOs array will
fit any S3C24XX platform, as per pattern from other archs.

ChangeLog v2->v3:
- Move the movement of the S3C64XX gpio.h file out of
  this patch and into the follow-up patch where it belongs.
ChangeLog v1->v2:
- Added an #ifdef ARCH_S3C24XX around the header inclusion
  in drivers/gpio/gpio-samsung.c as we would otherwise

Haojian Zhuang 389ee0c2ff ARM: hisi: rename hi3xxx to hisi
Since some new Hisilicon SoCs are not named as hi3xxx, rename mach-hi3xxx
to mach-hisi instead. And the pronounciation of "hisi" is similar to the
chinese pronounciation of Hisilicon. So Hisilicon guys like this name.

ARCH_HI3xxx will be renamed later since other drivers are using it and
they are still in linux-next git tree. So rename ARCH_HI3xxx later.

Kees Cook 19952a9203 stackprotector: Unify the HAVE_CC_STACKPROTECTOR logic between architectures
Instead of duplicating the CC_STACKPROTECTOR Kconfig and
Makefile logic in each architecture, switch to using
HAVE_CC_STACKPROTECTOR and keep everything in one place. This
retains the x86-specific bug verification scripts.

Tomasz Figa 70bacadbd0 ARM: S3C64XX: Select CPU_V6K instead of CPU_V6
All S3C64XX SoCs come with ARM1176JZF-s core, which fully supports
ARMv6K extensions. This patch lets the kernel use them on S3C6410 by
adding selection of CPU_V6K to ARCH_S3C64XX.
To use V6K extensions, these symbols must not be selected at the same
time, so this patch keeps only CPU_V6K selected for S3C64XX.

Alexandre Courbot d9a1beaa10 ARM: add basic support for Trusted Foundations
Trusted Foundations is a TrustZone-based secure monitor for ARM that
can be invoked using the same SMC-based API on supported platforms.
This patch adds initial basic support for Trusted Foundations using
the ARM firmware API. Current features are limited to the ability to
boot secondary processors.

Note: The API followed by Trusted Foundations does *not* follow the SMC
calling conventions. It has nothing to do with PSCI neither and is only
relevant to devices that use Trusted Foundations (like most Tegra-based
retail devices).

Laurent Pinchart 0d9fd6165a ARM: Kconfig: Mention Renesas ARM SoCs instead of SH-Mobile
Only the SH-Mobile product name is mentioned in the Kconfig descriptions
and help texts. This makes it difficult for external engineers working
on other Renesas platforms to find upstream platform support as the
combination of the SH-Mobile name and using the product number proved an
effective method of concealment.

Replace the "SH-Mobile" name with "Renesas ARM SoCs" in all the related
descriptions, help texts and comments.

Laurent Pinchart bf98c1eac1 ARM: Rename ARCH_SHMOBILE to ARCH_SHMOBILE_LEGACY
SH-Mobile platforms are transitioning from non-multiplatform to
multiplatform kernel. A new ARCH_SHMOBILE_MULTI configuration symbol has
been created to group all multiplatform-enabled SH-Mobile SoCs. The
existing ARCH_SHMOBILE configuration symbol groups SoCs that haven't
been converted yet.

This arrangement works fine for the arch/ code, but lots of drivers
needed on both ARCH_SHMOBILE and ARCH_SHMOBILE_MULTI depend on
ARCH_SHMOBILE only. In order to avoid changing them, rename
ARCH_SHMOBILE to ARCH_SHMOBILE_LEGACY, and create a new boolean
ARCH_SHMOBILE configuration symbol that is selected by both
ARCH_SHMOBILE_LEGACY and ARCH_SHMOBILE_MULTI.

panchaxari fe98914544 ARM: integrator: Default enable ARM_PATCH_PHYS_VIRT, AUTO_ZRELADDR
ARM_PATCH_PHYS_VIRT and AUTO_ZRELADDR has been enabled as default configs
to integrator platform.

Introduction of PHYS_VIRT config as default would enable phy-to-virt and
virt-to-phy translation function at boot and module loading time
and enforce dynamic reallocation of memory. AUTO_ZRELADDR config would
enable calculation of kernel load address at run time.

PHYS_VIRT config is mutually exclusive to XIP_KERNEL, XIP_KERNEL is used in
systems with NOR flash devices, and ZRELADDR config is mutually exclusive
to ZBOOT_ROM.

Requesting maintainers of Integrator platform to evaluate the changes on the
board and comment, as I dont have the board for testing and also requesting
an ACK.

Tomasz Figa 1db0287ab1 ARM: s3c64xx: Add support for DMA using generic amba-pl08x driver
This patch adds all required platform-specific data and initialization
code to support the generic amba-pl08x driver on S3C64xx SoCs.

Also some compatibility definitions are added to make the transition
from legacy API to DMA engine easier. The biggest hack here is passing
const char * pointers through DMA resource, casted to unsigned long,
but this is how Samsung DMA wrappers (used to support both s3c-dma and
DMA engine in drivers) are designed.
