The num_chipselect field for on-chip Blackfin SPI buses is supposed to
be 1 larger than the number of actual CSs available. This is because
the hardware starts counting at 1 and not 0. There is a field for "CS0",
but it is marked as "reserved" everywhere.

We don't need our own header and structure to hook up the ad5398 part,
so drop the custom resources for it.

Rather than write our own ADP switch driver, use the existing fixed
regulator driver and rewrite the platform resources accordingly.

Some peripherals might generate an error interrupt shortly after the
data interrupt due to the fact that the peripheral isn't serviced fast
enough. In most cases this isn't a problem and is expected behavior.
This hasn't been a problem on most parts since you simply don't request
the error interrupt (or you leave it disabled while there is an expected
state) and do the peripheral status checking in the data interrupt.
The Blackfin SIC allows people to prioritize data and error interrupts,
and the Blackfin CEC allows interrupts of equal or higher priority to
nest. The current default settings gives error interrupts a higher
priority than data interrupts. So if an error occurs while processing
the data interrupt, it will be serviced immediately.
However, the error interrupt on the BF537 SIC cannot be enabled on a
per-peripheral basis. Once the error interrupt is enabled for one
peripheral, it is automatically enabled for all peripherals.
Therefore lower the default multiplexed error interrupt priority so
most people need not worry themselves with this issue.

The NAND platform driver expects the registers to have a "mem"
resource type rather than "io".

With the recent kernel update the isp1362-hcd driver evaluates the
IORESOURCE_IRQ resource flags and requests the irq with the given
polarity/edge settings. However the ISP1362 config requires low
level/edge interrupts. Most of the Blackfin boards use some random
flag or no flag at all. Make all boards use a know good flag
IORESOURCE_IRQ_LOWEDGE.

Now that the common header defines everything and the SPI drivers are
using it, we can drop these duplicated global namespace polluters.

All file_operations should get a .llseek operation so we can make
nonseekable_open the default for future file operations without a
.llseek pointer.
The three cases that we can automatically detect are no_llseek, seq_lseek
and default_llseek. For cases where we can we can automatically prove that
the file offset is always ignored, we use noop_llseek, which maintains
the current behavior of not returning an error from a seek.
New drivers should normally not use noop_llseek but instead use no_llseek
and call nonseekable_open at open time. Existing drivers can be converted
to do the same when the maintainer knows for certain that no user code
relies on calling seek on the device file.
The generated code is often incorrectly indented and right now contains
comments that clarify for each added line why a specific variant was
chosen. In the version that gets submitted upstream, the comments will
be gone and I will manually fix the indentation, because there does not
seem to be a way to do that using coccinelle.
Some amount of new code is currently sitting in linux-next that should get
the same modifications, which I will do at the end of the merge window.
Many thanks to Julia Lawall for helping me learn to write a semantic
patch that does all this.

Fix the IRQ flag handling naming. In linux/irqflags.h under one configuration,
it maps:
local_irq_enable() -> raw_local_irq_enable()
local_irq_disable() -> raw_local_irq_disable()
local_irq_save() -> raw_local_irq_save()
...
and under the other configuration, it maps:
raw_local_irq_enable() -> local_irq_enable()
raw_local_irq_disable() -> local_irq_disable()
raw_local_irq_save() -> local_irq_save()
...
This is quite confusing. There should be one set of names expected of the
arch, and this should be wrapped to give another set of names that are expected
by users of this facility.
Change this to have the arch provide:
flags = arch_local_save_flags()
flags = arch_local_irq_save()
arch_local_irq_restore(flags)
arch_local_irq_disable()
arch_local_irq_enable()
arch_irqs_disabled_flags(flags)
arch_irqs_disabled()
arch_safe_halt()
Then linux/irqflags.h wraps these to provide:
raw_local_save_flags(flags)
raw_local_irq_save(flags)
raw_local_irq_restore(flags)
raw_local_irq_disable()
raw_local_irq_enable()
raw_irqs_disabled_flags(flags)
raw_irqs_disabled()
raw_safe_halt()
with type checking on the flags 'arguments', and then wraps those to provide:
local_save_flags(flags)
local_irq_save(flags)
local_irq_restore(flags)
local_irq_disable()
local_irq_enable()
irqs_disabled_flags(flags)
irqs_disabled()
safe_halt()
with tracing included if enabled.
The arch functions can now all be inline functions rather than some of them
having to be macros.

Rename h/w IRQ flags handling functions to be in line with what is expected for
the irq renaming patch. This renames local_*_hw() to hard_local_*() using the
following perl command:
perl -pi -e 's/local_irq_(restore|enable|disable)_hw/hard_local_irq_\1/ or s/local_irq_save_hw([_a-z]*)[(]flags[)]/flags = hard_local_irq_save\1()/' `find arch/blackfin/ -name "*.[ch]"`
and then fixing up asm/irqflags.h manually.
Additionally, arch/hard_local_save_flags() and arch/hard_local_irq_save() both
return the flags rather than passing it through the argument list.

Split the BF532 machine type BFIN_*_FIO_FLAG() functions to their own header
file to avoid circular #include problems as these functions require IRQ flag
handling, which requires asm/blackfin.h, which otherwise requires the header
file that defines these functions.
For good measure, also get rid of the inclusion of asm/blackfin.h from
mach/cdefBF532.h (which is circular) and defBF532.h (which is included by
asm/blackfin.h before including this header).

The common SPI layers take care of detecting CS conflicts and preventing
two devices from claiming the same CS. This causes problems for the GPIO
CS support we currently have as we are using CS0 to mean "GPIO CS". But
if we have multiple devices using a GPIO CS, the common SPI layers see
multiple devices using the virtual "CS0" and reject any such attempts.
To make both work, we introduce an offset define. This represents the
max number of hardware CS values that the SPI peripheral supports. If
the CS is below this limit, we know we can use the hardware CS. If it's
above, we treat it as a GPIO CS. This keeps the CS unique as seen by
the common code and prevents conflicts.

Make do_execve() take a const filename pointer so that kernel_execve() compiles
correctly on ARM:
arch/arm/kernel/sys_arm.c:88: warning: passing argument 1 of 'do_execve' discards qualifiers from pointer target type
This also requires the argv and envp arguments to be consted twice, once for
the pointer array and once for the strings the array points to. This is
because do_execve() passes a pointer to the filename (now const) to
copy_strings_kernel(). A simpler alternative would be to cast the filename
pointer in do_execve() when it's passed to copy_strings_kernel().
do_execve() may not change any of the strings it is passed as part of the argv
or envp lists as they are some of them in .rodata, so marking these strings as
const should be fine.
Further kernel_execve() and sys_execve() need to be changed to match.
This has been test built on x86_64, frv, arm and mips.

Architectures implement dma_is_consistent() in different ways (some
misinterpret the definition of API in DMA-API.txt). So it hasn't been so
useful for drivers. We have only one user of the API in tree. Unlikely
out-of-tree drivers use the API.
Even if we fix dma_is_consistent() in some architectures, it doesn't look
useful at all. It was invented long ago for some old systems that can't
allocate coherent memory at all. It's better to export only APIs that are
definitely necessary for drivers.
Let's remove this API.

dma_get_cache_alignment returns the minimum DMA alignment. Architectures
defines it as ARCH_DMA_MINALIGN (formally ARCH_KMALLOC_MINALIGN). So we
can unify dma_get_cache_alignment implementations.
Note that some architectures implement dma_get_cache_alignment wrongly.
dma_get_cache_alignment() should return the minimum DMA alignment. So
fully-coherent architectures should return 1. This patch also fixes this
issue.

Now each architecture has the own dma_get_cache_alignment implementation.
dma_get_cache_alignment returns the minimum DMA alignment. Architectures
define it as ARCH_KMALLOC_MINALIGN (it's used to make sure that malloc'ed
buffer is DMA-safe; the buffer doesn't share a cache with the others). So
we can unify dma_get_cache_alignment implementations.
This patch:
dma_get_cache_alignment() needs to know if an architecture defines
ARCH_KMALLOC_MINALIGN or not (needs to know if architecture has DMA
alignment restriction). However, slab.h define ARCH_KMALLOC_MINALIGN if
architectures doesn't define it.
Let's rename ARCH_KMALLOC_MINALIGN to ARCH_DMA_MINALIGN.
ARCH_KMALLOC_MINALIGN is used only in the internals of slab/slob/slub
(except for crypto).

The GPIO API was extended recently to include debounce functions, but
since the on-chip Blackfin GPIO modules don't support this stuff, make
a stub in the non-GPIOLIB case so drivers build properly.

MEM_GENERIC_BOARD depends on GENERIC_BOARD, but this flag was removed
in 4f25eb85d64640bc656e72917113a84701521b99, therefore all references
to it from the source can be removed.
