Updated uprobes patches

[Srikar Dronamraju]

Hi All, 

I just updated uprobes patches to rearrange some of the files. 
Architecture dependent files are moved to their corresponding arch
directories. 

Uprobes can now be built into the kernel or built as a module on 
i386, powerpc, and s390.
Please do review and let me know your comments.

The updated patches are available at /cvs/patches/uprobes directory.
The current set of patches are 

uprobes-all-i386.patch
uprobes-powerpc.patch
uprobes-s390.patch

Thanks and Regards
