Title:
  ARM instruction "srs" wrong behaviour

Status in QEMU:
  Confirmed

Bug description:
  Quote from ARM Architecture Reference Manual ARMv7-A and ARMv7-R :
  "Store Return State stores the LR and SPSR of the current mode to the stack 
of a specified mode"

  Problem:
  When executing this instruction, the register stored is CPSR instead of SPSR.

  Context:
  Using QEMU 1.2.0 to simulate a Zynq application (processor Cortex-a9 mpcore) 
with the following command line:
  qemu-system-arm -M xilinx-zynq-a9 -m 512 -serial null -serial mon:stdio -dtb 
/home/vcesson/workspace/xilinx_zynq.dtb -kernel 
install/tests/io/serial/current/tests/serial2 -S -s -nographic
