Corrected the parameters for the kernel. However, the remainder of the this bug
is the same as 1155.

[Bug tapsets/4510] probe scheduler.ctxswitch looks for wrong arg ($new) on 2.6.9-55.ELsmp x86_64

The 2.6.9-55.ELxmp x86_64 has the following function in kernel/sched.c

static inline
task_t * context_switch(runqueue_t *rq, task_t *prev, task_t *next)
{
...

However it the probe scheduler.ctxswitch is looking for $new rather than $next.
The following example illustrates the problem on the machine:

probe scheduler.ctxswitch
{
	printf("next_pid = %d\n", next_pid)
}

$ ../../install/bin/stap -v  /tmp/schedx.stpPass 1: parsed user script and 54
library script(s) in 750usr/10sys/767real ms.
semantic error: unable to find local 'new' near pc 0xffffffff8030ba14
