Re: [RFC] [PATCH] task_pt_regs for powerpc systems

 task_pt_regs() macro defines pt_regs for the given task,  this macro is

upcoming utrace features. 
 Below attached patch  defines this macro for powerpc arch. Please let 
me know your comments on this.

+#define task_pt_regs(tsk)	((struct pt_regs *)(tsk)->thread.regs)

The cast is unnecessary since tsk->thread.regs is already a struct
pt_regs *.  Also note that tsk->thread.regs will be NULL for a kernel
thread.
