Use FIXUP macros and resort them.

It is used __FIXUP_SECTION and __EX_TABLE_SECTION macros.

This is the first patch which does uaccess unification.
I choosed to do several patches to be able to use bisect
in future if any fault happens.

The same noMMU and MMU functions should be placed in
one file.

I would like to use asm-generic uaccess.h where are segment
macros defined. This is just first step.

This is first patch which clear part of uaccess.h.
uaccess.h will be clear later.

For 64bits arguments gcc caused that put_user macro
works with wrong value because of optimalization.
Adding volatile caused that gcc not optimized it.

It is possible to use (as Blackfin do) two put_user
macros with 32bits arguments but there is one more
instruction which is due to duplication zero return
value which is called put_user_asm macro.

This function was actually causing harm, by hiding
errors about invalid sized get_user/put_user accesses.
