Adding missing export symbols for loadable modules.

A userland read of more than PAGE_SIZE bytes from /dev/zero results in
(a) not all of the bytes returned being zero, and
(b) memory corruption due to zeroing of bytes beyond the user buffer.
This is caused by improper constraints on the assembly __clear_user function.
The constrints don't indicate to the compiler that the pointer argument is
modified. Since the function is inline, this results in double-incrementing
of the pointer when __clear_user() is invoked through a multi-page read() of
/dev/zero.

r0_ram pool was used for saving/restoring register
content if hw exception happen. This poll was replaced by
pt_pool_space with PT_SIZE size.
Based on this change SAVE_STATE_ARG_SPACE was removed which
caused that PTO offset is zero that's why is also removed.
r0_ram space was used as scratchpad by v850. In early
Microblaze Linux developing phase was this part of code
blindly copied.

The debugfs support added to the regulator API (which has been merged
in during this merge window) creates directories for regulators named
after the display names for the regulators so replace / as a separator
for multiple supplies with + in the SMDK6410 machine.

Reduce the logging output of s3c64xx_dma_init1() as it is not useful
for normal bootup (and we get an overall indication of the registration
of the PL180 DMA block).
This removes the following output from the log:
s3c64xx_dma_init1: registering DMA 0 (e0808100)
s3c64xx_dma_init1: registering DMA 1 (e0808120)

The call to s3c_gpio_cfgrange_nopull() takes a size and base
but this looks like it is trying to do base and end. This means
it is configuring too many GPIOs and on the case of the Cragganmore
means we're seeing an overflow of the ROW pins causing problems
with the keyboard driver.

This patch modifies the number of total GPIO lines for Bank F
for Samsung S5P6440 and S5P6450 SoCs from 2 to 16.
This is necessary as the GPIO lines from 0 to 13 are reserved
and only lines 14 and 15 are used. As during initialization,
the line number starts at 0, putting 2 does not solve the
intended purpose.
