Ping again.

This patchset is adding a generic infrastructure for luks support in
crash dumping, and it adds the support in x86 ARCH. Since the x86
related change is only located in kdump only files, won't impact other
x86 codes. Could you consider pick this into your tree?

And by the way, this is a kdump only fix, not related to KHO (Kexec
HandOver) which David suggested to adapt to earlier. Explained it here
to remove misunderstanding. 

Thanks
Baoquan
