LPAE enabled kernels use the 64-bit version of TTBR0 and TTBR1
registers. If we're running an LPAE kernel, fill the upper half
of TTBR0 with 0 because we're setting it to the idmap here (the
idmap is guaranteed to be < 4Gb) and fully restore TTBR1 instead
of just restoring the lower 32 bits. Failure to do so can cause
failures on resume from suspend when these registers are only
half restored.

when this bit is implemented by SoC vendor
(IMP - bit 9 - in L1 page table entry format).
When this bit is not implemented by SoC vendor
it doesn't mean that system has no other way
how to do ECC.
This patch ensures to show this message only when ECC

Make sure that inline assembler that expects 'r' operand
receives 32 bit value.

Before this fix in case of CONFIG_ARCH_PHYS_ADDR_T_64BIT and
CONFIG_ARM_PATCH_PHYS_VIRT __phys_to_virt function passed 64 bit
value to __pv_stub inline assembler where 'r' operand is
expected. Compiler behavior in such case is not well specified.
It worked in little endian case, but in big endian case
incorrect code was generated, where compiler confused which
part of 64 bit value it needed to modify. For example BE
snippet looked like this:

N:0x80904E08 : MOV      r2,#0
N:0x80904E0C : SUB      r2,r2,#0x81000000

when LE similar code looked like this

N:0x808FCE2C : MOV      r2,r0
N:0x808FCE30 : SUB      r2,r2,#0xc0, 8 ; #0xc0000000

Note 'r0' register is va that have to be translated into phys

To avoid this situation use explicit cast to 'unsigned long',
which explicitly discard upper part of phys address and convert
value to 32 bit. Also add comment so such cast will not be
removed in the future.

smp_cross_call() unconditionally in arch_irq_work_raise() and
crash the kernel on UP devices. Check to make sure we're running

By default, IRQ work is run from the tick interrupt (see
irq_work_run() in update_process_times()). When we're in full
NOHZ mode, restarting the tick requires the use of IRQ work and
if the only place we run IRQ work is in the tick interrupt we
have an unbreakable cycle. Implement arch_irq_work_raise() via
self IPIs to break this cycle and get the tick started again.
Note that we implement this via IPIs which are only available on
SMP builds. This shouldn't be a problem because full NOHZ is only
supported on SMP builds anyway.

Most of the kernel code assumes that max*pfn is maximum pfns because
the physical start of memory is expected to be PFN0. Since this
assumption is not true on ARM architectures, the meaning of max*pfn
is number of memory pages. This is done to keep drivers happy which
are making use of of these variable to calculate the dma bounce limit
using dma_mask.

Now since we have a architecture override possibility for DMAable
maximum pfns, lets make meaning of max*pfns as maximum pnfs on ARM
as well.

We need to start treating DMA masks as something which is specific to
the bus that the device resides on, otherwise we're going to hit all
sorts of nasty issues with LPAE and 32-bit DMA controllers in >32-bit
systems, where memory is offset from PFN 0.

In order to start doing this, we convert the DMA mask to a PFN using
the device specific dma_to_pfn() macro.  This is the reverse of the
pfn_to_dma() macro which is used to get the DMA address for the device.

This gives us a PFN mask, which we can then check against the PFN
limit of the DMA zone.

This patch (re)adds ARCH_BCM_MOBILE option to bcm_defconfig which was

"make savedefconfig"')

The IOMMU node's reg property contains completely bogus values! Somehow,
this had no practical effect, despite the fact the IOMMU driver appears
to be writing to those registers. I suppose that since no HW modules is
actually at that address, the writes simply had no effect.

Note that I'm not CCing stable here, even though the problem exists as
far back as v3.9, simply because this patch doesn't fix any observed
issue, and I don't want to run the risk of suddenly writing to some
registers and causing a regression.

The CPU_DYING notifier is called by cpu stopper task which
does not own the context held in the VFP hardware. Calling
vfp_force_reload() has no effect.
Replace it with clearing vfp_current_hw_state.

The OpenBlocks A7 board is designed and sold by PlatHome, and based on
a Kirkwood 6283 Marvell SoC. It is quite similar to the OpenBlocks A6
already supported in the kernel, with the following main differences:

 - The A6 uses a RTC on I2C, while the A7 uses the internal SoC RTC.

 - The A6 has one Ethernet port, while the A7 has two Ethernet ports

 - The A6 has only one USB port, while the A7 integrates a USB hub,
   which provides two front-side USB port, and an internal USB port as
   well.

 - The A6 has 512 MB of RAM, while the A7 has 1 GB of RAM.

 - Slightly different GPIOs for some functions.

Several of the options in bcm_defconfig have gotten out of date so
regenerate it with "make savedefconfig" to keep things fresh.

Currently ARCH_BCM has been used for Broadcom
Mobile V7 based SoCs. In order to allow other Broadcom
SoCs to also use mach-bcm directory and files, this patch
renames the original ARCH_BCM to ARCH_BCM_MOBILE, and
uses ARCH_BCM to define any Broadcom chip residing
in mach-bcm directory.

Changes from v2:
 - switch ARCH_MULTIPLATFORM from select to depends
 - remove 'default y' from BCM_MOBILE

Changes from v1:
 - fix alpha ordering in dts/Makefile
 - break into 4 patches for separate subsys

Convert ep93xx to use the OHCI platform driver and remove the
ohci-ep93xx bus glue driver.

Enable CONFIG_OHCI_HCD_PLATFORM in the ep93xx_defconfig so that USB
is still enabled by default on the EP93xx platform.

New u-boot versions no longer set the pinmuxing for Panda's DPI output,
and the muxing has to be done in the .dts file.

Add pinmuxing for DPI and TFP410. Without these, the DVI output on Panda
