Russell,

The latest mainline ARM build breaks with KPROBES enabled. Anand
Gadiyar did git bisect and figured out that below commit breaks the build.
	commit :4260415f6a3b92c5c986398d96c314df37a4ccbf

I tried matching the sections but failed to fix the build error. Below
is the hack patch to keep build working.

Regards,
Santosh
