fix the following 'make headers_check' warnings:

  usr/include/asm-arm/setup.h:17: include of <linux/types.h> is preferred over <asm/types.h>
  usr/include/asm-arm/setup.h:25: found __[us]{8,16,32,64} type without #include <linux/types.h>

Currently there are two instances of struct meminfo: one in
kernel/setup.c marked __initdata, and another in mm/init.c with
permanent storage.  Let's keep only the later to directly populate
the permanent version from arm_add_memory().

Also move common validation tests between the MMU and non-MMU cases
into arm_add_memory() to remove some duplication.  Protection against
overflowing the membank array is also moved in there in order to cover
the kernel cmdline parsing path as well.

Provide helpers for getting physical addresses or pfns from the
meminfo array, and use them.  Move for_each_nodebank() to
asm/setup.h alongside the meminfo structure definition.

Move platform independent header files to arch/arm/include/asm, leaving
those in asm/arch* and asm/plat* alone.

Use the newly introduced __used attribute in place of the deprecated
__attribute_used__.  Functionally the same.

Make the contents of the userspace asm/setup.h header consistent on all
architectures:

 - export setup.h to userspace on all architectures
 - export only COMMAND_LINE_SIZE to userspace
 - frv: move COMMAND_LINE_SIZE from param.h
 - i386: remove duplicate COMMAND_LINE_SIZE from param.h
 - arm:
   - export ATAGs to userspace
   - change u8/u16/u32 to __u8/__u16/__u32

nommu does not require the page table manipulation code in the
bootmem initialisation paths.  Move this into separate inline
functions.

Patch from Ben Dooks

The `make buildcheck` is erroneously reporting that the earlyparam
list is referencing items in the .init section as it is not itself
postfixed with .init
Also, as per rmk's suggestion, rename the __early_param to
.early_param to bring it into line with everything else

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!
