The functions uclinux_mtd_cleanup and uclinux_mtd_init do
not heed to be global. Add the needed keyword to the file
drivers/mtd/maps/uclinux.c to make these functions static.

On 32-bit architectures PAGE_ALIGN() truncates 64-bit values to the 32-bit
boundary. For example:

	u64 val = PAGE_ALIGN(size);

always returns a value < 4GB even if size is greater than 4GB.

The problem resides in PAGE_MASK definition (from include/asm-x86/page.h for
example):

#define PAGE_SHIFT      12
#define PAGE_SIZE       (_AC(1,UL) << PAGE_SHIFT)
#define PAGE_MASK       (~(PAGE_SIZE-1))
...
#define PAGE_ALIGN(addr)       (((addr)+PAGE_SIZE-1)&PAGE_MASK)

The "~" is performed on a 32-bit value, so everything in "and" with
PAGE_MASK greater than 4GB will be truncated to the 32-bit boundary.
Using the ALIGN() macro seems to be the right way, because it uses
typeof(addr) for the mask.

Also move the PAGE_ALIGN() definitions out of include/asm-*/page.h in
include/linux/mm.h.

Once upon a time, the MTD repository was using CVS.

This patch therefore removes all usages of the no longer updated CVS
keywords from the MTD code.

This also includes code that printed them to the user.

The cheesy uclinux mtd maps can be used for more than just the root device, so
I think we should drop the forcing.

Also, I feel like this is a policy decision that shouldnt be in the kernel in
the first place.  People who have been lazy and boot with uclinux mtd maps and
dont put root= into their commandline can simply add the appropriate root=
line either into their bootloader or into the compiled in bootargs.

We should not call mtd_put_device() in the uclinux MTD map driver.
Also consistently use phys/virt fields of maps map_info struct,
instead of mixing it with map_priv_1.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
