ioremap() twice on same memory mapped area?

[Parav Pandit]

Hi,
   
  I have memory mapped device and two device drivers wants to use the same area for different external device.
  To access the same space there is a global spin lock to avoid any race condition.
   
  Question is:
  Can both the driver call the ioremap() on the same space and get the different virtual address? or ioremap() should fail?
   
  Regards,
