[PATCH] solves freeze due to serial comm. on SMP

In the beginning of last year I reported a solid freeze problem with Linux
when I moved from UP to SMP. Some bughunting especially with kdb an hints
from AM I was able to nail it down to some SMP unsafe irq table handling
in serial.c.
I submitted the attached patch to Ted but that never made it to the
kernel. It _really_ solved the problem as I had a crash sometimes within
15 minutes and after applying it I reached uptimes over 100 days.

The problem is however that this patch applies to Linux-2.4.4 and serial.c
has had some tweaks in the meantime. Please merge it.
