kernel-fxtec-pro1x/arch/um/Makefile
Matt LaPlante 4b3f686d4a Attack of "the the"s in arch 
The patch below corrects multiple occurances of "the the"
typos across several files, both in source comments and KConfig files.
There is no actual code changed, only text.  Note this only affects the /arch
directory, and I believe I could find many more elsewhere. :)
