[PATCH] fix warning: incompatiable argument type of clear_user

[Wu Zhangjin <wuzhangjin@gmail.com>]

hi, Ralf

there are lots of warnings about the macro: clear_user in linux-mips.
in linux-2.6.29.3, it will come with errors, so, must be fixed.

the type of the second argument of access_ok should be void __user *,
but there is an un-needed (unsigned long) conversion before __cl_addr,
so remove the (unsigned long) will fix this problem.

       best regards, 
       Wu Zhangjin
