32d687cad3 Merge branch 'fixes-for-3.6' of git://git.linaro.org/people/mszyprowski/linux-dma-mapping
Pull DMA-mapping fixes from Marek Szyprowski:
 "Another set of fixes for ARM dma-mapping subsystem.

  Commit e9da6e9905 replaced custom consistent buffer remapping code
  with generic vmalloc areas.  It however introduced some regressions
  caused by limited support for allocations in atomic context.  This
  series contains fixes for those regressions.

  For some subplatforms the default, pre-allocated pool for atomic
  allocations turned out to be too small, so a function for setting its
  size has been added.

  Another set of patches adds support for atomic allocations to
  IOMMU-aware DMA-mapping implementation.

  The last part of this pull request contains two fixes for Contiguous
  Memory Allocator, which relax too strict requirements."

e829c66745 ARM: gemini: fix the gemini build
Test-compiling obscure machines I notice that the gemini (which
by the way lacks a defconfig) is broken since some time back.
Adding a simple missing include makes it build again.

28e515878f ARM: shmobile: armadillo800eva: enable rw rootfs mount
armadillo800eva default boot loader is "hermit",
and it's tag->u.core.flags has flag when kernel boots.
Because of this, ${LINUX}/arch/arm/kernel/setup.c :: parse_tag_core()
didn't remove MS_RDONLY flag from root_mountflags.
Thus, the rootfs is mounted as "readonly".
This patch adds "rw" kernel parameter,
and enable read/write mounts for rootfs

e26a6038d3 ARM: shmobile: mackerel: fixup usb module order
renesas_usbhs driver can play role as both Host and Gadget.
In case of Gadget, it requires not only renesas_usbhs
but also usb gadget module (like g_ether).
So, renesas_usbhs driver calls usb_add_gadget_udc() on probe time.

Because of this behavior,
Host port plays also Gadget role if kernel has both Host/Gadget support.

In mackerel case, from 0ada2da518
(ARM: mach-shmobile: mackerel: use renesas_usbhs instead of r8a66597_hcd)
usb0 plays Gadget role, and usb1 plays Host role,
and current mackerel board probes as usb1 -> usb0.
Thus, 1st installed usb gadget module (like g_ether) will be
assigned to usb1 (= usb Host port), and 2nd module to usb0 (= usb Gadget port).
It is very confusable for user.
This patch fixup usb modes probing order as usb0 -> usb1.

db43b18468 ARM: ux500: don't select LEDS_GPIO for snowball
Using 'select' in Kconfig is hard, a platform cannot just
enable a driver without also making sure that its subsystem
is there. Also, there is no actual code dependency between
the platform and the gpio leds driver.

Without this patch, building without LEDS_CLASS esults in:

drivers/built-in.o: In function `create_gpio_led.part.2':
governor_userspace.c:(.devinit.text+0x5a58): undefined reference to `led_classdev_register'
drivers/built-in.o: In function `gpio_led_remove':
governor_userspace.c:(.devexit.text+0x6b8): undefined reference to `led_classdev_unregister'

This reverts 8733f53c6 "ARM: ux500: Kconfig: Compile in leds-gpio
support for Snowball" that introduced the regression and did not
provide a helpful explanation.

In order to leave the GPIO LED code still present in normal
builds, this also enables the symbol in u8500_defconfig, in addition
to the other LED drivers that are already selected there.

1fc593feaf ARM: imx: build i.MX6 functions only when needed
The head-v7.S contains a call to the generic cpu_suspend function,
which is only available when selected by the i.MX6 code. As
pointed out by Shawn Guo, i.MX5 does not actually use any
functions defined in head-v7.S. It is also needed only for
the i.MX6 power management code and for the SMP code, so
we can restrict building this file to situations in which
at least one of those two is present.

Finally, other platforms with a similar file call it headsmp.S,
so we can rename it to the same for consistency.

Without this patch, building imx5 standalone results in:

c7a9b09b1a ARM: omap: allow building omap44xx without SMP
The new omap4 cpuidle implementation currently requires
ARCH_NEEDS_CPU_IDLE_COUPLED, which only works on SMP.

This patch makes it possible to build a non-SMP kernel
for that platform. This is not normally desired for
end-users but can be useful for testing.

Without this patch, building rand-0y2jSKT results in:

drivers/cpuidle/coupled.c: In function 'cpuidle_coupled_poke':
drivers/cpuidle/coupled.c:317:3: error: implicit declaration of function '__smp_call_function_single' [-Werror=implicit-function-declaration]

It's not clear if this patch is the best solution for
the problem at hand. I have made sure that we can now
build the kernel in all configurations, but that does
not mean it will actually work on an OMAP44xx.

c944b0b935 ARM: imx6: spin the cpu until hardware takes it down
Though commit 602bf40 (ARM: imx6: exit coherency when shutting down
a cpu) improves the stability of imx6q cpu hotplug a lot, there are
still hangs seen with a more stressful hotplug testing.

It's expected that once imx_enable_cpu(cpu, false) is called, the cpu
will be taken down by hardware immediately, and the code after that
will not get any chance to execute.  However, this is not always the
case from the testing.  The cpu could possibly be alive for a few
cycles before hardware actually takes it down.  So rather than letting
cpu execute some code that could cause a hang in these cycles, let's
make the cpu spin there and wait for hardware to take it down.

6c0274cbe6 ARM: shmobile: sh73a0: fixup RELOC_BASE of intca_irq_pins_desc
sh73a0 :: intca_irq_pins_desc irq table had conflict
from irq 552 to irq 557 before.
But the second controller was simply trampling the
first one by way of the -EEXIST case from irq_alloc_desc_at().

But now, we have irqdomain support from
1d6a21b0a6
(sh: intc: initial irqdomain support)

The irqdomain code has simply tightened down the sanity checks and
error path. So, sh73a0 CPU board got some WARNING when booting now.
This patch fixup RELOC_BASE to solve this issue.

16339464c5 ARM i.MX6q: Add virtual 1/3.5 dividers in the LDB clock path
The ldb_di[01]_podf is implemented as a clk-divider that
divides by 1 or 2. In reality, the ldb_di[01]_ipu_div
dividers divide by either 3.5 or 7. Adding a fixed factor
of 1/3.5 fixes their children's clock rates.

This should probably be converted to rate table based dividers,
once available.
