2012-10-19openrisc: pass correct arg to schedule_tailJonas Bonn
schedule_tail() requires that the 'prev' task be passed as an argument to it. This arg is set in _switch, just before 'returning' to one of the ret_* functions where schedule_tail is invoked. Signed-off-by: Jonas Bonn <jonas@southpole.se>
2012-05-08openrisc: use scratch regs in atomic syscallJonas Bonn
The function sys_or1k_atomic was using call-saved registers without restoring their value before returning. This is a faux pas: either we need to restore their values or use scratch regs; the latter is less code so that's the route this patch takes. Thanks to David Hennerström for doing most of the heavy-lifting in tracking this one down.

2012-03-06openrisc: sanitize use of orig_gpr11Jonas Bonn
The pt_regs struct had both a 'syscallno' field and an 'orig_gpr11' field and it wasn't really clear how these were supposed to be used. This patch removes the syscallno field altogether and makes orig_gpr11 work more like other architectures: keep track of syscall number in progress or hold -1 for non-syscall exceptions.
