Hi,

I have sent version V4 of the patchset now. My plan was to include the fix for
"Kconfig recursive dependency" issue reported for IA64 architecture. But I
would need some more time to understand the problem and provide a correct
fix. Hence the V4 patchset was sent with a fix to only address the problem
reported in this mail.
