494cc76061 ARM: tegra: multi-platform conversion
This branch converts Tegra to support multi-platform/single-zImage.
 
 One header is made accessible to drivers. The earlyprintk implementation
 is moved to the multi-platform location. Some Kconfig changes are made
 to enable multi-platform. Some dead files are deleted.
 
 The APIs exposed in the now-global tegra-powergate.h should be replaced
 with standard reset and power domain APIs in the future.
 
 This branch is based on (part of) the previous soc pull request.

6cd2f8e7da ARM: tegra: core SoC support development
This branch includes major development on the core Tegra SoC support code
 in the mach-tegra directory:
 
 * SMP support for Tegra114.
 * Exposes SoC chip ID and revision through standard sysfs files.
 * System-level suspend/resume for Tegra20/30. At present, this only
   supports "LP2" mode (CPU power-down), but provides the basis to
   implement "LP0"/"LP1" (various levels of core/chip power-down) in the
   hopefully near future.
 * A minor cleanup of a duplicate include, which was introduced in this
   branch.
 
 This branch is based on the previous cleanup pull request.

This series adds support for the pinctrl/gpio module on all arch-vt8500

 As part of the review process, some tidy up is also done to
 drivers/of/base.c to remove some code that is being constantly duplicated.
 
 Also, a patch for the bcm2835 pinctrl driver is included to take advantage
 of the new of/base.c code.

arm: vt8500: Add pinctrl driver for arch-vt8500

This series adds support for the pinctrl/gpio module on all arch-vt8500
supported SoCs.

As part of the review process, some tidy up is also done to
drivers/of/base.c to remove some code that is being constantly duplicated.

Also, a patch for the bcm2835 pinctrl driver is included to take advantage
of the new of/base.c code.

And since the GENERIC_GPIO in arch/arm/ will be gone away, this adds

b008848020 ARM: 7688/1: add support for context tracking subsystem
commit 91d1aa43 (context_tracking: New context tracking susbsystem)
generalized parts of the RCU userspace extended quiescent state into
the context tracking subsystem.  Context tracking is then used
to implement adaptive tickless (a.k.a extended nohz)

To support the new context tracking subsystem on ARM, the user/kernel
boundary transtions need to be instrumented.

For exceptions and IRQs in usermode, the existing usr_entry macro is
used to instrument the user->kernel transition.  For the return to
usermode path, the ret_to_user* path is instrumented.  Using the
usr_entry macro, this covers interrupts in userspace, data abort and
prefetch abort exceptions in userspace as well as undefined exceptions
in userspace (which is where FP emulation and VFP are handled.)

For syscalls, the slow return path is covered by instrumenting the
ret_to_user path.  In addition, the syscall entry point is
instrumented which covers the user->kernel transition for both fast
and slow syscalls, and an additional instrumentation point is added
for the fast syscall return path (ret_fast_syscall).

On Cortex-A15 (r0p0..r3p2) the TLBI/DSB are not adequately shooting down
all use of the old entries. This patch implements the erratum workaround
which consists of:

1. Dummy TLBIMVAIS and DSB on the CPU doing the TLBI operation.
2. Send IPI to the CPUs that are running the same mm (and ASID) as the
   one being invalidated (or all the online CPUs for global pages).
3. CPU receiving the IPI executes a DMB and CLREX (part of the exception
   return code already).

698613b638 ARM: iWMMXt: always enable iWMMXt support with PJ4 CPUs
Jason Cooper reports these build errors:

/.../arch/arm/kernel/pj4-cp0.c:40: undefined reference to `iwmmxt_task_switch'
make: *** [vmlinux] Error 1

This is caused because the PJ4 code explicitly references the iWMMXt
code, but doesn't require it to be built.  Fix this by ensuring that
iWMMXt is always enabled with PJ4.

This change:

* Stops selecting some ARM errata that are incompatible with multi-
  platform. This requires that you use a bootloader that enables the

faeb9e36d6 ARM: EXYNOS: drop "select HAVE_SCHED_CLOCK"
The Kconfig symbol HAVE_SCHED_CLOCK got removed in v3.4,
with commit 6905a65879b5 ("ARM: Make the sched_clock
framework mandatory"). Drop the last two select statements
for that symbol too. They're useless now.

e7b64391ba ARM: kill Hynix h720x platform
The platform was merged about 10 years ago, and has seen few updates
for most of the time since. The people that merged the code seem
no longer interested in it either, so let's remove it now.

1c6ba37b3d arm-soc: bug fixes for 3.9-rc3
Things are calming down for arm-soc as well. This set of bug fixes is
 dominated in size by the at91 platform bug fixes. Some of them were
 meant to go through the framebuffer tree during the merge window, but
 since the framebuffer maintainer could not be reached, I offered to
 take them here. The other notable at91 change is the addition of pinctrl
 definitions to fix the NAND controller.
 
 The rest are mostly simple regression fixes:
 
 * Our removal of VIRT_TO_BUS conflicted with Stephen Rothwell's
   renaming of the Kconfig symbol. You will get a trivial merge conflict
   here, we still want to remove it.
 * missing bits for clocks on imx and s5pv210
 * missing header inclusions in mmp and shmobile
 * typos in s5pv210 camera and vt8500 clock support code
 
 and three trivial fixes for pre-3.8 bugs:
 
 * an old bogus build warning in the joystick driver
 * a misleading Kconfig description
 * a NULL pointer check on davinci

b4811bacbc ARM: fix CONFIG_VIRT_TO_BUS handling
887cbce0 "arch Kconfig: centralise CONFIG_ARCH_NO_VIRT_TO_BUS"
and  4febd95a8 "Select VIRT_TO_BUS directly where needed" from
Stephen Rothwell changed globally how CONFIG_VIRT_TO_BUS is
selected, while my own a5d533ee0 "ARM: disable virt_to_bus/
virt_to_bus almost everywhere" was merged at the same time and
changed which platforms select it on ARM.

The result of this conflict was that we again see CONFIG_VIRT_TO_BUS
on all ARM systems. This patch fixes up the problem and removes
CONFIG_ARCH_NO_VIRT_TO_BUS again on ARM.

cca438b57e ARM: ux500: bump arch nr of GPIOs
Set the number of GPIOs for Ux500 to 392. Reasoning:

- Internal pinctrl "Nomadik" SoC: 288 GPIOs
- Then each Ux500 system has one or two GPIO expanders at
  maximum 24 GPIOs each:
  TC35892 expander: 24 GPIOs
  STMPE1601 or 1801 Expander: 24 GPIOs
- Then AB8500/AB8505/AB8540: 56 GPIOs

Sum: maximum 392 GPIOs - no more no less.

3a768d0463 Merge branch 'spear/multiplatform' into next/multiplatform
The spear platform has been cleaned up a lot by Viresh
Kumar, and is relatively easy to convert to multiplatform,
getting us one more step closer to having all ARMv7
platforms included.

I originally did this before 3.8 but merging it never
worked out so far, mostly because of conflicts against
patches in the DMA tree, but also because I did not push very
hard for these.

* spear/multiplatform:
  ARM: spear: enable spear13xx in multi_v7_defconfig
  ARM: spear: fix build error in restart.c
  ARM: spear: use multiplatform configuration options.
  ARM: spear: rename duplicate pl080_plat_data
  ARM: spear: make clock driver independent of headers
  ARM: spear: move generic.h and pl080.h into private dir
  ARM: spear: move all files to mach-spear
  ARM: spear: move spear.h and misc_regs.h into plat-spear
  ARM: spear: merge Kconfig files
  ARM: spear: make spear3xx/6xx mach/spear.h files identical
  ARM: spear: move identical headers to plat-spear/include/mach
  ARM: spear: unify mach/generic.h and mach/irqs.h
  ARM: spear13xx: make mach/dma.h local

that's what I did here.

There is no defconfig file for gemini, which has lead to a lot

and the reset logic work again, and fixes the build warnings

f1ac922dec ARM: bcm2835: convert to multi-platform
This allows BCM2835 be included in a kernel build that supports multiple
SoCs at once, which is useful for distro kernels.

This change:
* Moves bcm2835's debug-macro.S into ARM's include/debug/, and hooks it
  into the relevant menu.
* Moves bcm2835's Kconfig into its own directory, as seems typical for
  multi-platform conversions.
* Removes bcm2835_soc.h, and moves the content to the files where it was
  used; just one usage per define.
* Deletes some headers and Makefile.boot that aren't needed now that we
  support multi-platform.
