James Bottomley warns that inclusion of linux/fs.h in a low level
driver was always a danger signal. This patch moves
memory_read_from_buffer() from fs.h to string.h and fixes includes in
existing memory_read_from_buffer() users.

* This patch replaces the dangerous lvalue version of cpumask_of_cpu
with new cpumask_of_cpu_ptr macros. These are patterned after the
node_to_cpumask_ptr macros.
In general terms, if there is a cpumask_of_cpu_map[] then a pointer to
the cpumask_of_cpu_map[cpu] entry is used. The cpumask_of_cpu_map
is provided when there is a large NR_CPUS count, reducing
greatly the amount of code generated and stack space used for
cpumask_of_cpu(). The pointer to the cpumask_t value is needed for
calling set_cpus_allowed_ptr() to reduce the amount of stack space
needed to pass the cpumask_t value.
If there isn't a cpumask_of_cpu_map[], then a temporary variable is
declared and filled in with value from cpumask_of_cpu(cpu) as well as
a pointer variable pointing to this temporary variable. Afterwards,
the pointer is used to reference the cpumask value. The compiler
will optimize out the extra dereference through the pointer as well
as the stack space used for the pointer, resulting in identical code.
A good example of the orthogonal usages is in net/sunrpc/svc.c:
case SVC_POOL_PERCPU:
{
unsigned int cpu = m->pool_to[pidx];
cpumask_of_cpu_ptr(cpumask, cpu);
*oldmask = current->cpus_allowed;
set_cpus_allowed_ptr(current, cpumask);
return 1;
}
case SVC_POOL_PERNODE:
{
unsigned int node = m->pool_to[pidx];
node_to_cpumask_ptr(nodecpumask, node);
*oldmask = current->cpus_allowed;
set_cpus_allowed_ptr(current, nodecpumask);
return 1;
}

Now that the original SMC_USE_PXA_DMA specific code will always being
built if CONFIG_ARCH_PXA is defined, so to make this part of the code
to be PXA public, and still prevent it from being built if support of
PXA is not selected.
A SMC91X_USE_DMA flag is added to the platform data to allow platform
to choose its usage of DMA. Note this flag itself is so named to be
generic enough (assuming other platforms can also use DMA).
It keeps backward compatibility to set the SMC91X_USE_DMA flag if
SMC_USE_PXA_DMA is still defined.

Now one can use the following code
#define SMC_IO_SHIFT lp->io_shift
to make SMC_IO_SHIFT a variable. This, however, will slightly increase
the CPU overhead and have negative impact on the network performance.
The tradeoff is, this can be specified in the smc91x platform data so
that multiple boards support can be built in a single zImage.

And also favors the usage of SMC91X_NOWAIT over the hardcoded SMC_NOWAIT
by converting "nowait" (module parameter overridable) to platform flag.
There are several possibilities:
1. platform data present - preferred and use as is
2. platform data absent - use "nowait", it can be:
a. SMC_NOWAIT if defined
b. default to 0 if SMC_NOWAIT isn't defined
c. overriden by module parameter

Let's simplify the logic and avoid confusion, the use of SMC91X_USE_*
is favored than SMC_CAN_USE_*, if platform data isn't given, convert
the hardcoded SMC_CAN_USE_* to SMC91X_USE_*.

IRQ trigger type can be specified in the IRQ resource definition by
IORESOURCE_IRQ_*, we need only one way to specify this.
This also fixes the following small issue:
To allow dynamic support for multiple platforms, when those relevant
macros are not defined for one specific platform, the default case
will be:
- SMC_DYNAMIC_BUS_CONFIG defined
- and SMC_IRQ_FLAGS = IRQF_TRIGGER_RISING
While if "irq_flags" is missing when defining the smc91x_platdata,
usually as follows:
static struct smc91x_platdata xxxx_smc91x_data = {
.flags = SMC91X_USE_XXBIT,
};
The lp->cfg.irq_flags will always be overriden by the above structure
(due to a memcpy), thus rendering lp->cfg.irq_flags to be "0" always.
(regardless of the default SMC_IRQ_FLAGS or IORESOURCE_IRQ_* flags)
Fixes this by forcing to use IORESOURCE_IRQ_* flags if present, and
make the only user of smc91x_platdata.irq_flags (renesas/migor) to
use IORESOURCE_IRQ_*.

Make it a bit more obvious that the card has been claimed by the
mmc_test driver so that people don't have to wonder why their block
device never shows up.

Commit c8b3e02 renamed a variable, but missed one reference to it
inside a WARN_ON, causing it to incorrectly trigger.

The ADMA code path assumes that the 3 byte alignment fix doesn't cross
a page boundary. I'm not convinced this is worth supporting, but at
least print a warning in the off chance we'll actually see such a request.

Add tests that make sure the driver properly checks the blocks and
blksz fields and doesn't assume the sg list has a size that perfectly
matches the current request.

Add a couple of tests to make sure the host driver handles highmem
memory pages properly. Unfortunately there is no way to guarantee an
allocation below 4 GB in i386, so it might give you addresses that
are out of reach for the hardware (OTOH, so will any other highmem
allocation in the kernel).

Ensure that the s3cmci host controller is turned off
when the machine is shutdown, otherwise we end up
leaving the card powered and processing insertion and
removal events after the system prints "System halted."
