"A range of ARM fixes. Biggest change is the stage-2 attributes used
for for hyp mode which were wrong. I've killed some bits in a couple
of DT files which turned out not to be required, and a few other
fixes.
One fix touches code outside of arch/arm, which is related to sorting
out the DMA masks correctly. There is a long standing issue with the
conversion from PFNs to addresses where people assume that shifting an
unsigned long left by PAGE_SHIFT results in a correct address. This
is not the case with C: the integer promotion happens at assignment
after evaluation. This fixes the recently introduced dma_max_pfn()
function, but there's a number of other places where we try this
directly on an unsigned long in the mm code"

Since commit 9e8147bb5e
"ARM: imx6q: move low-power code out of clock driver"
the kernel fails to boot on i.MX6Q/D if preemption is
enabled (CONFIG_PREEMPT=y). The kernel just hangs
before the console comes up.
The above commit moved the initalization of the low-power
mode setting (enabling clocked WAIT states), which was
introduced in commit 83ae20981a
"ARM: imx: correct low-power mode setting", from
imx6q_clks_init to imx6q_pm_init. Now it is called
much later, after all cores are enabled.
This patch moves the low-power mode initialization back
to imx6q_clks_init again (and to imx6sl_clks_init).

Due to commit 88f718e3fa
"ARM: pxa: delete the custom GPIO header" some drivers fail
compilation, for example like this:
In file included from sound/soc/pxa/spitz.c:28:0:
sound/soc/pxa/spitz.c: In function ‘spitz_ext_control’:
arch/arm/mach-pxa/include/mach/spitz.h:111:30: error:
‘PXA_NR_BUILTIN_GPIO’ undeclared (first use in this function)
#define SPITZ_SCP_GPIO_BASE (PXA_NR_BUILTIN_GPIO)
(etc.)
This is caused by implicit inclusion of <mach/irqs.h> from
various board-specific headers under <mach/*> in the PXA
platform. So we take a sweep over these, and for every such
header that uses PXA_NR_BUILTIN_GPIO or PXA_GPIO_TO_IRQ()
we explicitly #include "irqs.h" so that we satisfy the
dependency in the board include file alone.

of function ‘PXA_GPIO_TO_IRQ’ [-Werror=implicit-function-declaration]
free_irq(PXA_GPIO_TO_IRQ(RDY_GPIO_PIN), par);
This was caused by commit 88f718e3fa
"ARM: pxa: delete the custom GPIO header"
This is because it was previously getting the macro PXA_GPIO_TO_IRQ
implicitly from <linux/gpio.h> which in turn implicitly included

When unlocking a spinlock, we require the following, strictly ordered
sequence of events:
<barrier> /* dmb */
<unlock>
<barrier> /* dsb */
<sev>
Whilst the code does indeed reflect this in terms of the architecture,
the final <barrier> + <sev> have been contracted into a single inline
asm without a "memory" clobber, therefore the compiler is at liberty to
reorder the unlock to the end of the above sequence. In such a case,
a waiting CPU may be woken up before the lock has been unlocked, leading
to extremely poor performance.
This patch reworks the dsb_sev() function to make use of the dsb()
macro and ensure ordering against the unlock.

During __v{6,7}_setup, we invalidate the TLBs since we are about to
enable the MMU on return to head.S. Unfortunately, without a subsequent
dsb instruction, the invalidation is not guaranteed to have completed by
the time we write to the sctlr, potentially exposing us to junk/stale
translations cached in the TLB.
This patch reworks the init functions so that the dsb used to ensure
completion of cache/predictor maintenance is also used to ensure
completion of the TLB invalidation.

Commit ad6492b8 added much needed memblock_virt_alloc_low() and further
commit 07bacb3 {memblock, bootmem: restore goal for alloc_low} fixed
the issue with low memory limit thanks to Yinghai. But even after all
these fixes, there is still one case where the limit check done with
ARCH_LOW_ADDRESS_LIMIT for low memory fails. Russell pointed out the
issue with 32 bit LPAE machines in below thread.
https://lkml.org/lkml/2014/1/28/364
Since on some LPAE machines where memory start address is beyond 4GB,
the low memory marker in memblock will be set to default
ARCH_LOW_ADDRESS_LIMIT which is wrong. We can fix this by letting
architectures set the ARCH_LOW_ADDRESS_LIMIT using another export
similar to memblock_set_current_limit() but am not sure whether
its worth the trouble. Tell me if you think otherwise.
Rather am just trying to fix that one broken case using
memblock_virt_alloc() in setup code since the memblock.current_limit
is updated appropriately makes it work on all ARM 32 bit machines.

TI_EDMA fell out of automatically selected options in the multi_v7

we need to re-enable explicitly to not regress some platforms.
The rest is just the result of running 'make multi_v7_defconfig + make

DEBUG_FS used to be selected by COMMON_CLK_DEBUG, which was enabled
by tegra_defconfig. However, this config option no longer exists, so
no longer selects DEBUG_FS, and nothing else selects it either. So,
"make tegra_defconfig" no longer enables DEBUG_FS in .config.
Rebuild tegra_defconfig on top of next-20140424, while manually
re-enabling DEBUG_FS.
Reasons for removed entries are:
- I2C_MUX: selected by MEDIA_SUBDRV_AUTOSELECT
- DRM_PANEL: selected by DRM_TEGRA
- NEW_LEDS: selected by many things; at least VT

multi_v7_defconfig was missing a large number of options that were in
tegra_defconfig. This patch adds them. The changes fall into the
following categories:
* Enable more Tegra SoC options/drivers.
* Enable more drivers for Tegra boards.
* Enable more options that are useful for running distros.
The patch removes a few lines as well, simply because those options are
now selected by something else, and "make savedefconfig" removes them. I
verified that the options appear in .config after
"make multi_v7_defconfig".

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.
