[MIPS] Generate SIGILL again

2005-12-01T11:05:14+00:00

    
The rdhwr emulation accidentally swallowed the SIGILL from most other
illegal instructions.  Make sure to return -EFAULT by default.

[PATCH] sched: disable preempt in idle tasks

2005-11-09T15:56:33+00:00

Run idle threads with preempt disabled.

Also corrected a bugs in arm26's cpu_idle (make it actually call schedule()).
How did it ever work before?

Might fix the CPU hotplugging hang which Nigel Cunningham noted.

We think the bug hits if the idle thread is preempted after checking
need_resched() and before going to sleep, then the CPU offlined.

After calling stop_machine_run, the CPU eventually returns from preemption and
into the idle thread and goes to sleep.  The CPU will continue executing
previous idle and have no chance to call play_dead.

By disabling preemption until we are ready to explicitly schedule, this bug is
fixed and the idle threads generally become more robust.

[PATCH] remove ioctl32_handler_t

2005-11-09T15:56:00+00:00

Some architectures define and use this type in their compat_ioctl code, but
all of them can easily use the identical ioctl_trans_handler_t type that is
defined in common code.

Fix return type of setup_frame variants

2005-11-07T18:05:39+00:00

    
Since 2.6.13-rc1 setup_frame and its variants return int.  But some bits
were missed in the conversion.
