Subject: [PATCH 0/14] score - New architecure port to SunplusCT S+CORE
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.
