 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 *. 

True.

Also note that tsk->thread.regs will be NULL for a kernel 
thread.

Yes, users of task_pt_regs will verify for NULL.  Updated patch attached 
below.

Can you send a cleanup patch against powerpc.git instead ?

Thanks !
