[PATCH] fix mdelay

[Paul Mackerras]

The mdelay macro uses a variable called `msec'.  The effect of this is
that the statements msec = 1; mdelay(msec); will spin for an
indeterminate length of time, because you end up with a statement like
this:

	({unsigned long msec=(msec); while (msec--) udelay(1000);}))

and the msec in that statement is uninitialized.  This actually bit me
in sound/ppc/awacs.c.  The patch below changes the name of the loop
variable to __ms, which will hopefully have a lower chance of a
collision.

Please apply.

Paul.
