Stafford Horne 6dfd85ada8 openrisc: Properly store r31 to pt_regs on unhandled exceptions ... [ Upstream commit 812489ac4dd91144a74ce65ecf232252a2e406fb ] In commit 91993c8c2e ("openrisc: use shadow registers to save regs on exception") the unhandled exception path was changed to do an early store of r30 instead of r31. The entry code was not updated and r31 is not getting stored to pt_regs. This patch updates the entry handler to store r31 instead of r30. We also remove some misleading commented out store r30 and r31 instructrions. I noticed this while working on adding floating point exception handling, This issue probably would never impact anything since we kill the process or Oops right away on unhandled exceptions.
