This patch fixes the following compile error caused by
commit 4016a1390d07f15b267eecb20e76a48fd5c524ef
(mm/nommu.c: return 0 from kobjsize with invalid objects):
<-- snip -->
...
CC mm/nommu.o
/home/bunk/linux/kernel-2.6/git/linux-2.6/mm/nommu.c: In function 'kobjsize':
/home/bunk/linux/kernel-2.6/git/linux-2.6/mm/nommu.c:112: error: 'memory_end' undeclared (first use in this function)
/home/bunk/linux/kernel-2.6/git/linux-2.6/mm/nommu.c:112: error: (Each undeclared identifier is reported only once
/home/bunk/linux/kernel-2.6/git/linux-2.6/mm/nommu.c:112: error: for each function it appears in.)
make[2]: *** [mm/nommu.o] Error 1
<-- snip -->
The patch also removes now no longer required memory_{start,end}
declarations inside access_ok().

There doesn't seem to be any fixed location for memory_{start,end} among
all architectures, but since mm/nommu.c already has an #include <asm/uaccess.h>
and the non-MMU access_ok anyway needs them this seems to be the logical
way to fix this compile error.
