hi, all

I just update "RT_PREEMPT for loongson" to the latest RT_PREEMPT
(patch-2.6.29.1-rt8), welcome to pull & test it.

$ git clone git://dev.lemote.com/rt4ls.git
or
http://dev.lemote.com/http_git/rt4ls.git

this version include basic-RT support for mips, ftrace support for mips
(static function tracer/dynamic function tracer/function graph
tracer/system call tracer). 

* current status

the "system call tracer" need to fix when compiled in 64bit, because
there are several sys_call_table entries for different mips64
standards(o32, n32), currently, i only use the one in
arch/mips/kernel/scall64-o32.S via EXPORT(sys_call_table).

the "function graph tracer" is not stable under 100% load(lots of
"find /" background). 

best regards,
Wu Zhangjin
