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.

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.

ARM: SoC board updates for 3.14
This branch is reducing in size for every release since most board-related
changes have started happening in devicetrees now. Still, we have some things
going on here.
* Renesas platforms are still adding a bit more legacy device support, something
that should trail off shortly as they move to full DT.
* We group most defconfig updates into this branch out of old habits
* Removal of legacy OMAP2 platforms over to DT continues, and a handful of old
code is being removed here.

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

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

Merge tag 'sound-3.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai:
"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

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.

Fix select-induced Kconfig warning for ZBOOT_ROM
warning: (ARCH_MULTIPLATFORM && ARCH_CLPS711X && ARCH_PXA && SOC_EXYNOS5440 && ARCH_EMEV2) selects AUTO_ZRELADDR which has unmet direct dependencies (!ZBOOT_ROM) 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.

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.

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.

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 have colliding definitions when compiling S3C64XX. - Rename inclusion guard in the header file.

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).

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.

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.

Features:
- SWIOTLB has tracing added when doing bounce buffer.
- Xen ARM/ARM64 can use Xen-SWIOTLB. This work allows Linux to
safely program real devices for DMA operations when running as
a guest on Xen on ARM, without IOMMU support.*1
- xen_raw_printk works with PVHVM guests if needed.
Bug-fixes:
- Make memory ballooning work under HVM with large MMIO region.
- Inform hypervisor of MCFG regions found in ACPI DSDT.
- Remove deprecated IRQF_DISABLED.
- Remove deprecated __cpuinit.
[*1]:
"On arm and arm64 all Xen guests, including dom0, run with second stage
translation enabled. As a consequence when dom0 programs a device for a
DMA operation is going to use (pseudo) physical addresses instead
machine addresses. This work introduces two trees to track physical to
machine and machine to physical mappings of foreign pages. Local pages
are assumed mapped 1:1 (physical address == machine address). It
enables the SWIOTLB-Xen driver on ARM and ARM64, so that Linux can
translate physical addresses to machine addresses for dma operations
when necessary. " (Stefano).

Pull Xen updates from Konrad Rzeszutek Wilk:
"This has tons of fixes and two major features which are concentrated
around the Xen SWIOTLB library.
The short <blurb> is that the tracing facility (just one function) has
been added to SWIOTLB to make it easier to track I/O progress.
Additionally under Xen and ARM (32 & 64) the Xen-SWIOTLB driver
"is used to translate physical to machine and machine to physical
addresses of foreign[guest] pages for DMA operations" (Stefano) when
booting under hardware without proper IOMMU.
There are also bug-fixes, cleanups, compile warning fixes, etc.
The commit times for some of the commits is a bit fresh - that is b/c
we wanted to make sure we have the Ack's from the ARM folks - which
with the string of back-to-back conferences took a bit of time. Rest
assured - the code has been stewing in #linux-next for some time.

ARM: 7888/1: seccomp: not compatible with ARM OABI
Make sure that seccomp filter won't be built when ARM OABI is in use, since there is work needed to distinguish calling conventions. Until that is done (which is likely never since OABI is deprecated), make sure seccomp filter is unavailable in the OABI world.

Merge branch 'for-linus' of git://git.linaro.org/people/rmk/linux-arm
Pull ARM updates from Russell King:
"Included in this series are:
1. BE8 (modern big endian) changes for ARM from Ben Dooks
2. big.Little support from Nicolas Pitre and Dave Martin
3. support for LPAE systems with all system memory above 4GB
4. Perf updates from Will Deacon
5. Additional prefetching and other performance improvements from Will.
6. Neon-optimised AES implementation fro Ard.
7. A number of smaller fixes scattered around the place.
There is a rather horrid merge conflict in tools/perf - I was never
notified of the conflict because it originally occurred between Will's
tree and other stuff. Consequently I have a resolution which Will
forwarded me, which I'll forward on immediately after sending this
mail.
The other notable thing is I'm expecting some build breakage in the
crypto stuff on ARM only with Ard's AES patches. These were merged
into a stable git branch which others had already pulled, so there's
little I can do about this. The problem is caused because these
patches have a dependency on some code in the crypto git tree - I
tried requesting a branch I can pull to resolve these, and all I got
each time from the crypto people was "we'll revert our patches then"
which would only make things worse since I still don't have the
dependent patches. I've no idea what's going on there or how to
resolve that, and since I can't split these patches from the rest of
this pull request, I'm rather stuck with pushing this as-is or
reverting Ard's patches.
Since it should "come out in the wash" I've left them in - the only
build problems they seem to cause at the moment are with randconfigs,
and since it's a new feature anyway. However, if by -rc1 the
dependencies aren't in, I think it'd be best to revert Ard's patches"
I resolved the perf conflict roughly as per the patch sent by Russell,
but there may be some differences. Any errors are likely mine. Let's
see how the crypto issues work out..
