On Oprofile ARMv7 the PMNC_D bit was set to lower the PMU IRQs
and so to decrease the risk of errata #628216 from appearing.
The effect of setting the PMNC_D bit is that the CCNT counter
is divided by 64, making the program counter events count
inaccurate.
The new OMAP3 r4 cores should have that errata fixed.
The PMNC_D bit should not be set, this patch fixes it.

This avoids races in the VFP code where the dead thread may have
state on another CPU. By moving this code to exit_thread(), we
will be running as the thread, and therefore be running on the
current CPU.
This means that we can ensure that the only local state is accessed
in the thread notifiers.

Add pseudo-DMA by FIQ to the S3C24XX SPI driver. This allows the driver
to get DMA-like performance where there are either no free DMA channels or
when doing transfers that required both TX and RX data paths.
Since this patch requires the addition of an assembly file to hold the FIQ
code, we rename the module (instead of adding a rename of the .c file to
this patch). We expect most users are loading this via udev and thus
there should be no change to the userland configuration.

This driver was merged before the ep93xx core support was added
for the keypad clock and acquiring/releasing the necessary gpio's.
Now that the proper support is in the ep93xx core this driver
needs to be updated to work correctly.
Summary of changes:
1) Remove some unused members from the platform data.
2) Remove the custom KEY macro and use the ones available in
<linux/input/matrix_keypad.h>
3) Remove the keypad_{readl/writel} macros and just use
__raw_{readl/writel} directly.
4) Update the clk_set_rate() call to work with the core support.
5) Cleanup the probe routine and remove some unneeded messages.
6) Use the ep93xx core functions to acquire and release the gpio's.
7) Fix the clk_get() call to get the keypad clock.

Allow the use of another DMA controller driver in atmel-mci sd/mmc driver.
This adds a generic dma_slave pointer to the mci platform structure where
we can store DMA controller information. In atmel-mci we use information
provided by this structure to initialize the driver (with new helper
functions that are architecture dependant).
This also adds at32/avr32 chip modifications to cope with this new access
method.

The Kconfigs for in-tree floating point emulation do not allow building
as modules. That leaves the Acorn FPEmulator module. I found two public
releases of this as a binary module for 2.1 and 2.2 kernels, optimized
for ARMV4.[1] If there is a resurgence of interest in this, the symbols
can always be re-exported.
This allows the EXPORT_SYMBOL_ALIAS() hack to be removed. The ulterior
motive here is that EXPORT_SYMBOL_ALIAS() makes it harder to sort the
resulting kernel symbol tables. Sorted symbol tables will allow faster
symbol resolution during module loading.
Note that fp_send_sigs() and fp_printk() are simply aliases for existing
exports and add no obvious value. Similarly fp_enter could easily be
renamed to kern_fp_enter at the point of definition. Therefore removing
EXPORT_SYMBOL_ALIAS will not serve as a material obstacle to re-adding
the exports should they be desired in future.
Build tested only.

Commit 023bf6f "linker script: unify usage of discard definition"
changed the linker scripts for all architectures except for ARM.
I can find no discussion about this ommision, so here are the changes
for ARM.
These changes are exactly parallel to the ia64 case.
"ia64 is notable because it first throws away some ia64 specific
subsections and then include the rest of the sections into the final
image, so those sections must be discarded before the inclusion."
Not boot-tested. In build testing, the modified linker script generated
an identical vmlinux file.
[I would like to be able to rely on this unified discard definition.
I want to sort the kernel symbol tables to allow faster symbol
resolution during module loading. The simplest way appears to be
to generate sorted versions from vmlinux.o, link them in to vmlinux,
_and discard the original unsorted tables_.
This work is driven by my x86 netbook, but it is implemented at a
generic level. It is possible it will benefit some ARM systems also.]

The raw_spin* namespace was taken by lockdep for the architecture
specific implementations. raw_spin_* would be the ideal name space for
the spinlocks which are not converted to sleeping locks in preempt-rt.
Linus suggested to convert the raw_ to arch_ locks and cleanup the
name space instead of using an artifical name like core_spin,
atomic_spin or whatever

There is not enough users to warrant its existence, and it is actually
an obstacle to progress with the new DMA API which cannot cover this
case properly.

There's no point having the hardware support background operations
if we issue a cache operation, and then wait for it to complete
before calculating the address of the next operation. We gain no
advantage in the cache controller stalling the bus until completion.
What we should be doing is using the 'wait' time productively by
calculating the address of the next operation, and only then waiting
for the previous operation to complete. This means that cache
operations can occur in parallel with the CPU calculating the next
address.

No idea if this platform actually uses cpufreq_get(), but it doesn't
have any cpufreq drivers. That's not to say it doesn't use cpufreq_get()

be killed off.

Fix:
arch/arm/mach-sa1100/generic.c:117: error: redefinition of 'cpufreq_get'
include/linux/cpufreq.h:299: error: previous definition of 'cpufreq_get' was here
cpufreq_get() is used on these platforms to tell drivers what the CPU
frequency is, and therefore the bus frequency - which is critical for
setting the PCMCIA and LCD timings. Adding ifdefs to these drivers to
select cpufreq_get() or some other interface adds confusion. Making
these drivers use some other interface for the normal paths and cpufreq
stuff for the cpufreq notifier is insane as well.
(Why x86 can't provide a version of cpufreq_get() which returns the
CPU frequency when CPUFREQ is disabled is beyond me, rather than
requiring a dummy zero-returning cpufreq_get(). Especially as they
do:
unsigned long khz = cpufreq_get(cpu);
if (!khz)
khz = tsc_khz;
In other words, if CPUFREQ is disabled, get it from tsc_khz - why
not provide a dummy cpufreq_get() which returns tsc_khz?)

When the VFP notifier is called for flush_thread(), we may be
preemptible, meaning we might migrate to another CPU, which means
referencing the current CPU number without some form of locking is
invalid, and can cause data corruption.
For the most cases, this isn't a problem since atomic notifiers are run
under rcu lock, which for most configurations results in preemption
being disabled - except when the preemptable tree-based rcu
implementation is selected.
Let's make it safe anyway.

Earlier, the hwmod code had considered the OCP_SYSCONFIG.CLOCKACTIVITY
bits to be incremental power saving bits, controlling internal IP
block clock gates. This was a misapprehension. The CLOCKACTIVITY
bits are used to indicate, in advance, which clocks will be cut when
the module acknowledges an idle request. This enables the IP block to
take whatever action is necessary to complete any in-progress work
before asserting its IdleAck.
In the current Linux-OMAP code, this implies that the clock framework
should be changing module CLOCKACTIVITY bits as module clocks are enabled
and disabled. We don't do that yet, but in the future, we should.
This must wait until the clock tree is annotated with omap_hwmod pointers
(or vice-versa). In the meantime, drop most of the hwmod code that
controls CLOCKACTIVITY bits to avoid confusion.
This patch has benefited from many illuminating discussions with (in
alphabetical order) Benoît Cousson <b-cousson@ti.com>, Rajendra Nayak
<rnayak@ti.com>, and Sebastien Sabatier <s-sabatier1@ti.com>.

Replace the existing u8 array of module MPU IRQ lines with a struct
that includes a name - similar to the existing struct
omap_hwmod_dma_info. Device drivers can then use
platform_get_resource_byname() to retrieve specific IRQs without nasty
dependencies on array ordering.

This patch fills in the OCP_SYSCONFIG.AUTOIDLE handling in the OMAP
hwmod code.
After this patch, the hwmod code will set the module AUTOIDLE bit
(generally <module>.OCP_SYSCONFIG.AUTOIDLE) to 1 by default upon
enable. If the hwmod flag HWMOD_NO_OCP_AUTOIDLE is set, AUTOIDLE will
be set to 0 upon enable. Upon module disable, AUTOIDLE will be set to
1.
Enabling module autoidle should save some power. The only reason to
not set the OCP_SYSCONFIG.AUTOIDLE bit is if there is a bug in the
module RTL, e.g., the MPUINTC block on OMAP3.

The code that reprograms the SDRC memory controller during CORE DVFS,
mach-omap2/sram34xx.S:omap3_sram_configure_core_dpll(), does not
ensure that all L3 initiators are prevented from accessing the SDRAM
before modifying the SDRC AC timing and MR registers. This can cause
memory to be corrupted or cause the SDRC to enter an unpredictable
state. This patch places that code behind a Kconfig option,
CONFIG_OMAP3_SDRC_AC_TIMING for now, and adds a note explaining what
is going on. Ideally the code can be added back in once supporting
code is present to ensure that other initiators aren't touching the
SDRAM. At the very least, these registers should be reprogrammable
during kernel init to deal with buggy bootloaders. Users who know
that all other system initiators will not be touching the SDRAM can
also re-enable this Kconfig option.
This is a modification of a patch originally written by Rajendra Nayak
<rnayak@ti.com> (the original is at http://patchwork.kernel.org/patch/51927/).
Rather than removing the code completely, this patch just comments it out.
Thanks to Benoît Cousson <b-cousson@ti.com> and Christophe Sucur
<c-sucur@ti.com> for explaining the technical basis for this and for
explaining what can be done to make this path work in future code.

leaving the clock24xx.c namespace, use a more durable method: split the

Each context has a backend area of real memory, where it stores the

- Allocate without ioremapping
- Allocate at defined physical addresses
- Allows larger VRAM area and larger allocations

Correct boilerplates after files split. Also shorten them a bit - use
standart GPL wording (as per http://lkml.org/lkml/2007/5/1/220) and
drop changelog, which only entry about h3800 support and abstracted
EGPIOs is just confusing now, as both of these features are gone.

Split common h3600.c into three separate files: h3100.c, h3600.c and
h3xxx.c (the latter contains common code for h3100/h3600)
Copyright boilerplates and #includes are copied intact and will be
cleaned up later.

As all existing code was converted to gpiolib, drop no more
used pre-gpiolib (bit-shifted) GPIO definintions.
Supply new gpiolib-friendly definitions for GPIOs which
don't have them yet.

After conversion to gpiolib there's still some GPIOs left, that get
configured in *_mach_init() as outputs (using direct operations
on GPCR/GPDR registers), but otherwise unused. These GPIOs are mainly
sound related and should be configured by corresponding driver once
it is written.
Drop this initialisation and configure all GPIOs as input.

As all the remaining users of these definitions
(in pcmcia/sa1100_h3600 driver) were converted to gpio_to_irq(),
they can be safely removed.

As all users of assign_h3600_egpio now converted to gpiolib, we
can safely remove all assign_h3600_egpio handling code and

Use of gpio_request/gpio_free in some callbacks may look ugly, but
corresponding drivers (sa1100_serial and sa1100_fb) don't provide (yet)
init/exit hooks and registering these gpios in *_mach_init is also
not possible, because htc-gpio driver starts a bit later...

h3100 and h3600 have different sets of LCD-controlling gpios,
which mapped to the same "abstracted" EGPIO.
As we plan to get rid of those abstracted egpios completely, we
need to separate these helper functions.
