Multiple symbols same address in vmlinux map file? huh?

hi there,

When doing a 'nm' on the vmlinux I see that some different
symbols are at the same address. This seems very strange
to me. Can anyone explain this?

What I typed (to see the duplicates only)...

nm vmlinux-2.4.18-14 | awk 'BEGIN{oldval=01;} { if ($1==oldval) {
if(plast) { print "\n"; print oldrow;} print $0; plast=0} else plast=1;
oldrow=$0; oldval=$1}' - | more

What I saw....

[stuff removed...]
c0305a78 d emergency_lock
c0305a78 d emergency_pages

c0303100 d i8259A_irq_type
c0303100 D i8259A_lock

c0386628 B jiffies
c0386628 B jiffies_64

Any idea?

Thanks again,
