The sa1111 socket driver oopses when removed:

Unable to handle kernel NULL pointer dereference at virtual address 000003b0
pgd = c1b40000

This is because we try to dereference a NULL 's' to obtain the next
pointer.  Fix this.

module_param(bool) used to counter-intuitively take an int.  In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.

It's time to remove the int/unsigned int option.  For this version
it'll simply give a warning, but it'll break next kernel version.

Since commit 6384fd "ARM: pxa: rename IRQ_GPIO to PXA_GPIO_TO_IRQ",
I got buid errors due to implicit declaration of function 'IRQ_GPIO'.

Use common gpio_to_irq() to replace machine dependant macro IRQ_GPIO().

The includes in the pxa2xx_cm_x2xx PCMCIA driver are rather random;
the driver doesn't require anything from these headers except the
cpu_is_xxx() macros which come from another include.

The concern is that it's getting these definitions via mach/system.h,
which is supposed to only be included by arch/arm/kernel/process.c.
As this header is scheduled for cleanup (and elimination) keeping
the status quo will cause build errors.  So lets fix properly and
independent of the future work.

- use spinlock to protect shadow register.

This tries to clear up the confusion between integers and iomem pointers
in the marvell pxa platform. MMIO addresses are supposed to be __iomem*
values, in order to let the Linux type checking work correctly. This
patch moves the cast to __iomem as far back as possible, to the place
where the MMIO virtual address windows are defined.

This fixes the failure to register the IRQ_RTCAlrm alarm as a wakeup

After 2.6.34 changes, __pxa2xx_drv_pcmcia_probe() was replaced by
sa1111_pcmcia_add(). That unfortunately means that configure_sockets()
is not called, leading to MECR not being set properly, leading to
strange crashes.

Tested on pxa255+sa1111, I do not have lubbock board nearby. Perhaps
cleaner solution exists?

The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.

This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel.  A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).

Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.
