patches to patches ? or, developers can figure this out....

this is a corrected version of the fix-smp patch found on:

   http://user-mode-linux.sourceforge.net/patches.html

The line in the available patch incorrectly attempts to patch
arch/um/os/drivers/ethertap_kern.c instead of um/os-Linux/drivers
(a clean tree):

And thus fails to apply completely.
