Hi tglx, Arnd, Kyle, Sam and linus,

According to your comment last week, We had updated the linux/score code,
use arch blackfin code as reference.
 
because some reasons below, I have not fixed these problems you mentioned
 
1:      bdflush is not a nop, remove it?

2:      because module_arch_cleanup, makcine_halt, machine_power_off and 
some other funcs are global, 
        so i have not move them into .h and not declare them as static 
inline.

I still leave these syscalls there, bacause i think it clear to everybody
even linux have the new syscall replace them.

4:      asm/atomic.h and asm/bitops.h generic version have not finished,
        so I dont updated them.

Once the kernel code update, I will remove these code.

6:      sys_sigaltstack should rename to sys_rt_sigaltstack?

7:      use score-linux compile linux/score kernel still have some 
warning, 
        but we think it not the problems in score head files.
 
8:      score have big and little endian support, now we only use 
        little endian running linux.
