DPLL1 reprogramming to a different rate is actually blocked inside
omap1_select_table_rate(), resulting in the defalut rate of 60 MHz
always used instead of the one selected in .config. OTOH, in
omap1_defconfig we currently rely on Kconfig options for the supported
MHz rates in case of boards which boot with dpll1 not set correctly by
their boot loaders.
This means that before we allow for reprogramming of dpll1 rate, we
should remove all unsafe clock selections from omap1_defconfig,
otherwise it will stop booting on boards with imperfect boot loaders,
as it would always try to change to 216MHz.
Keep only one safe clock rate per each supported xtal frequency, i.e.
60MHZ dpll1 for 12MHz xtal and 182MHz dpll1 for 13MHz xtal.
BTW, this change goes into the direction of removing all OMAP1 clock
rate options, planned for next merge window.

60MHz
Commit e9b7086b80c4d9e354f4edc9e280ae85a60df408 (ARM: OMAP: Fix
reprogramming of dpll1 rate) fixed a regression for systems that
did not rely on bootloader set rates.
However, it also introduced a new problem where the rates selected
in .config would not take affect as omap1_select_table_rate
currently refuses to reprogram DPLL1 if it's already initialized.
This was not a problem earlier, as the reprogramming was done
earlier with ck_dpll1_p->rate uninitialized.
Fix this by forcing the reprogramming on systems booting at rates
below 60MHz. Note that the long term fix is to make the rates
SoC specific later on.
Thanks for Janusz Krzysztofik <jkrzyszt@tis.icnet.pl> for figuring
this one out.

On OMAP-L138 platform, EDMA event queue 0 should be used for audio
transfers so that they are not starved by video data moving on event queue 1.
Commit 48519f0ae03bc7e86b3dc93e56f1334d53803770 (ASoC: davinci: let platform
data define edma queue numbers) had a side-effect of changing this behavior
by making the driver actually honor the platform data passed.
Fix this now by passing event queue 0 as the queue to be used for audio
transfers.

The function setup_vpif_input_channel_mode() used the VSCLKDIS register

used a different clock from channel 1.

When gpio core dynamically allocate gpio number for a port, it starts
from the end of the total range, 0 ~ ARCH_NR_GPIOS. That said, the
earlier a port gets probed, the bigger gpio number it gets assigned.
To match this, the irq_base for gpio should be assigned from
'MXC_GPIO_IRQ_START + ARCH_NR_GPIOS' decreasingly.

The of_irq_init() expects the callback passed by .data of of_device_id
return 'int' instead of 'void'. This patch fixes it to have
irq_init_cb() return the correct value, and in turn have the secondary
interrupt controller (gpio in this case) initialized properly and also
eliminate the error message 'of_irq_init: children remain, but no
parents' which was overlooked before.

The SWP instruction is deprecated on ARMv6 and with ARMv7 it will be
UNDEFINED when CONFIG_SWP_EMULATE is selected. In this case, probing a
SWP instruction will cause an oops when the kprobes emulation code
executes an undefined instruction.
As the SWP instruction should be rare or non-existent in kernels for
ARMv6 and later, we can simply avoid these problems by not allowing
probing of these.

There is a kprobes testcase for the instruction "strd r2, [r3], r4".
This has unpredictable behaviour as it uses r3 for register writeback
addressing and also stores it to memory.
On a cortex A9, this testcase would fail because the instruction writes
the updated value of r3 to memory, whereas the kprobes emulation code
writes the original value.
Fix this by changing testcase to used r5 instead of r3.

Commit 4294f8baa ("ARM: gic: add irq_domain support") defines irq_start
as irq_start = (irq_start & ~31) + 16; On a platform with a GIC and a
CPU without PPIs, this results in irq_start being off by 16.
This patch fixes gic_init so that we only carve out a PPI space when
PPIs exist for the GIC being initialised.

When multiple GICs exist on a platform (RealView PB1176/11MP),
we must make sure the PM notifier block is only registered
once, otherwise we end up corrupting the PM notifier list.
The fix is to only register the notifier when initializing
the first GIC, as the power management functions seem
to iterate over all the registered GICs.
Tested on PB11MP and PB1176.

When compiling kprobes-test-thumb.c an error like below may occur:
/tmp/ccKcuJcG.s:19179: Error: offset out of range
This is caused by the compiler underestimating the size of the inline
assembler instructions containing ".space 0x1000" and failing to spill
the literal pool in time to prevent the generation of PC relative load
instruction with invalid offsets.
The fix implemented by this patch is to replace a single large .space
directive by a number of 4 byte .space's. This requires splitting the
macros which generate test cases for branch instructions into two forms:
one with, and one without support for inserting extra code between
branch and target.

dma_alloc_coherent wants to split pages after allocation in order to
reduce the memory footprint. This does not work well with GFP_COMP
pages, so drop this flag before allocation.
This patch is ported from arch/avr32
(commit 3611553ef985ef7c5863c8a94641738addd04cff).

The bitops functions (e.g. _test_and_set_bit) on ARM do not have unwind
annotations and therefore the kernel cannot backtrace out of them on a
fatal error (for example, NULL pointer dereference).
This patch annotates the bitops assembly macros with UNWIND annotations
so that we can produce a meaningful backtrace on error. Callers of the
macros are modified to pass their function name as a macro parameter,
enforcing that the macros are used as standalone function implementations.

There are already cache type decoding functions, so use those instead
of custom decode code which only works for ARMv6.
