The value of the AMR register at the time of the exception is made available in gp_regs[PT_AMR] of the siginfo.
But its already available there in uctxt->uc_mcontext.regs->amr while inside the signal delivery context in the user space. The pt_regs already got updated with new AMR register. Then why we need gp_regs to also contain AMR as well ?
