strcmp was lost when all other string functions were removed,
but we still have an optimized version for this on CRISv32,
so any driver built as a module would not have access to this symbol.

In a similar manner, we had optimized versions of
csum_partial_copy_from_user and __do_clear_user
but no exported symbols for them, breaking bunch of other drivers
when built as a module.

At the same time, move EXPORT_SYMBOL(__copy_user) and
EXPORT_SYMBOL(__copy_user_zeroing) C-files so it's
located together with the function definition.

Most of these have been purged years ago.  This one silently lived
on until commit 69349c2d

    "kconfig: fix IS_ENABLED to not require all options to be defined"

In the above, we use some macro trickery to create a conditional that
is valid in CPP and in C usage.  However that trickery doesn't sit
well if you have the legacy "-traditional" flag enabled.  You'll get:

  AS      arch/cris/arch-v10/lib/checksum.o
In file included from <command-line>:4:0:
include/linux/kconfig.h:23:0: error: syntax error in macro parameter list
make[2]: *** [arch/cris/arch-v10/lib/checksum.o] Error 1

Everything builds fine w/o "-traditional" so simply drop it from this
location as well.

Function __copy_user_zeroing in arch/lib/usercopy.c had the wrong parameter
set as __user, and in include/asm-cris/uaccess.h, it was not set at all for
some of the calling functions.

This will cut the number of warnings quite dramatically when using sparse.

While we're here, remove useless CVS log and correct confusing typo.

Adrian Bunk reported another compile error with a SVN head GCC:

...
  CC      arch/cris/arch-v10/lib/string.o
/home/bunk/linux/kernel-2.6/git/linux-2.6/arch/cris/arch-v10/lib/string.c:138:
error: lvalue required as increment operand
/home/bunk/linux/kernel-2.6/git/linux-2.6/arch/cris/arch-v10/lib/string.c:138:
error: lvalue required as increment operand
/home/bunk/linux/kernel-2.6/git/linux-2.6/arch/cris/arch-v10/lib/string.c:139:
error: lvalue required as increment operand
...

This is due to the use of the construct:

	*((long*)dst)++ = lc;

Which isn't legal since casts don't return an lvalue.

The solution is to import the implementation from newlib,
which is continually autotested together with GCC mainline,
and uses the construct:

	*(long *) dst = lc; dst += 4;

Since this is an import of a file from newlib, I'm not touching
the formatting or correcting any checkpatch errors.

As for the earlier fix for memset.c, even if the two files for
CRIS v10 and CRIS v32 are identical at the moment, it might
be possible to tweak the CRIS v32 version.
Thus, I'm not yet folding them into the same file, at least not
until we've done some research on it.

This is due to the use of the construct:

	*((long*)dst)++ = lc;

Which is no longer legal since casts don't return an lvalue.

The solution is to import the implementation from newlib,
which is continually autotested together with GCC mainline,
and uses the construct:

	*(long *) dst = lc; dst += 4;

With this change, the generated code actually shrinks 76 bytes
since gcc notices that it can use autoincrement for the move
instruction in CRIS.

   text    data     bss     dec     hex filename
    304       0       0     304     130 memset.old.o
   text    data     bss     dec     hex filename
    228       0       0     228      e4 memset.o

Since this is an import of a file from newlib, I'm not touching
the formatting or correcting any checkpatch errors.

Note also that even if the two files for the CRIS v10 and CRIS v32

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!
