irq_domain_add_simple() was a stop-gap measure until complete irq_domain
support was complete. This patch removes the irq_domain_add_simple()
interface.
This patch also drops the explicit irq_domain initialization performed
by the mach-versatile code because the versatile interrupt controller
already has irq_domain support built into it. This was a bug that was
hanging around quietly for a while, but with the full irq_domain which
actually verifies that irq_domain ranges are available it would cause
the registration to fail and the system wouldn't boot.

This patch removes the simplistic implementation of irq_domains and enables
the powerpc infrastructure for all irq_domain users. The powerpc
infrastructure includes support for complex mappings between Linux and
hardware irq numbers, and can manage allocation of irq_descs.
This patch also converts the few users of irq_domain_add()/irq_domain_del()
to call irq_domain_add_legacy() instead.
v3: Fix bug that set up too many irqs in translation range.

Part of the series to unify the irq remapping mechanisms in the
kernel. A follow up patch will copy the powerpc implementation into
kernel/irq/irqdomain.c, which will be a lot easier if the structures
are identical.
Where they differ, I've chose to use the powerpc names since there is
a lot more code using those names.

This set of changes are fixing various section mismatch warnings which
look to be completely valid. Primerily, those which are fixed are those
which can cause oopses by manipulation of driver binding via sysfs. For
example: calling code marked __init from driver probe __devinit
functions.
Some of these changes will be reworked at the next merge window when the
underlying reasons are sorted out. In the mean time, I think it's
important to have this fixed for correctness.
Also included in this set are fixes to various error messages in OMAP -
including making them gramatically correct, fixing a few spelling
errors, and more importantly, making them greppable by unwrapping them.
Tony Lindgren has acked all these patches, put them out for testing a
week ago, and I've tested them on the platforms I have.

we shouldn't oops.

It's useful to print the error code when a called function fails so a
diagnosis of why it failed is possible. In this case, it fails because
we try to register some data for the wl12xx driver, but as the driver
is not configured, a stub function is used which simply returns -ENOSYS.
Let's do the simple thing for -rc and print the error code.
Also, the return code from platform_register_device() at each of these
sites was not being checked. Add some checking, and again print the
error code.
This should be fixed properly for the next merge window so we don't
issue error messages merely because a driver is not configured.

While trying to debug my OMAP platforms, they emitted this message:
omap_hwmod: %s: enabled state can only be entered from initialized, idle, or disabled state
The following backtrace said it was from a function called '_enable',
which didn't provide much clue. Grepping didn't find it either.
The message is wrapped, so unwrap the message so grep can find it. Do
the same for three other messages in this file.

Found by review.
omap4_sdp4430_wifi_mux_init() is called by an __init marked function,
and only calls omap_mux_init_gpio() and omap_mux_init_signal() which
are both also an __init marked functions.
The only reason this doesn't issue a warning is because the compiler
inlines omap4_sdp4430_wifi_mux_init() into omap4_sdp4430_wifi_init().
So, lets add the __init annotation to ensure this remains safe should
the compiler choose not to inline.

omap_vc_i2c_init: I2C config for all channels must match.
This doesn't help identify what the problem is. Fix this message to

omap_vc_i2c_init: I2C config for vdd_iva does not match other channels (0).
omap_vc_i2c_init: I2C config for vdd_mpu does not match other channels (0).
This allows us to identify which voltage domains have a problem, and
what the I2C configuration state (a boolean, i2c_high_speed) setting
being used actually is.
From this we find that omap4_core_pmic has i2c_high_speed false, but

Prevent OMAP UARTs from going idle while they are still transferring
data in PIO mode. This works around an oversight in the OMAP UART
hardware present in OMAP34xx and earlier: an idle UART won't send a
wakeup when the TX FIFO threshold is reached. This causes long delays
during data transmission when the MPU powerdomain enters a low-power
mode. The MPU interrupt controller is not able to respond to
interrupts when it's in a low-power state, so the TX buffer is not
refilled until another wakeup event occurs.
This fix changes the erratum i291 DMA idle workaround. Rather than
toggling between force-idle and no-idle, it will toggle between
smart-idle and no-idle. The important part of the workaround is the
no-idle part, so this shouldn't result in any change in behavior.
This fix should work on all OMAP UARTs. Future patches intended for
the 3.4 merge window will make this workaround conditional on a
"feature" flag, and will use the OMAP36xx+ TX event wakeup support.

The ARM kernel uses undefined instructions to implement
BUG/BUG_ON(). This leads to problems where people don't read one
line above the Oops message and see the "kernel BUG at ..."
message and so they wrongly assume the kernel has hit an
undefined instruction.
Instead of printing:
Internal error: Oops - undefined instruction: 0 [#1] PREEMPT SMP
print
Internal error: Oops - BUG: 0 [#1] PREEMPT SMP
This should prevent people from thinking the BUG_ON was an
undefined instruction when it was actually intentional.

armv7's flush_cache_all() flushes caches via set/way. To
determine the cache attributes (line size, number of sets,
etc.) the assembly first writes the CSSELR register to select a
cache level and then reads the CCSIDR register. The CSSELR register
is banked per-cpu and is used to determine which cache level CCSIDR
reads. If the task is migrated between when the CSSELR is written and
the CCSIDR is read the CCSIDR value may be for an unexpected cache
level (for example L1 instead of L2) and incorrect cache flushing
could occur.
Disable interrupts across the write and read so that the correct
cache attributes are read and used for the cache flushing
routine. We disable interrupts instead of disabling preemption
because the critical section is only 3 instructions and we want
to call v7_dcache_flush_all from __v7_setup which doesn't have a
full kernel stack with a struct thread_info.
This fixes a problem we see in scm_call() when flush_cache_all()
is called from preemptible context and sometimes the L2 cache is
not properly flushed out.

fbdev fixes for 3.3
It includes:
- compile fix for fsl-diu-fb
- fix for a suspend/resume issue in atmel_lcdfb
- fix for a suspend/resume issue in OMAP
- workaround for a hardware bug to avoid physical damage in OMAP
- really trivial dead code removal in intelfb
* tag 'fbdev-fixes-for-3.3-1' of git://github.com/schandinat/linux-2.6:
atmel_lcdfb: fix usage of CONTRAST_CTR in suspend/resume
intelfb: remove some dead code
drivers/video: compile fixes for fsl-diu-fb.c
OMAPDSS: HDMI: PHY burnout fix
OMAP: 4430SDP/Panda: add HDMI HPD gpio

* A series of OMAP regression fixes for merge window fallout
* Two patches for Davinci, one removes some misdefined clocks, the other
is a regression fix for merge window fallout
* Two patches that makes Broadcom bcmring build again (and removes a
bunch of unused code in the process)

Upstream commit d1fce9c115eeb93e01c01732dfe9a86cf76009cf
"ARM: restart: bcmring: use new restart hook"
breaks building of this platform, since what used to be the
last field of the MACHINE_START/END block didn't have a
trailing comma. Once another field was added below, we get:

i.MX SDMA: Fix burstsize settings

__kuser_cmpxchg64 has a return path using bx lr to get back to the caller.
This is actually ok since the code in question is predicated on
CONFIG_CPU_32v6K, but for the sake of consistency using the usr_ret
macro is probably better.

Several changes to PMC have to be managed for adding this support:
- alternate prescaler location for both MCKR and PCKR
- alternate CSS length for PCKR
- added cpu_is_at91sam9x5() to functional switches
- manage UTMI bias like sam9g45 chip family
