Sorry for being so naieve, but where is the staging tree?
I included elf notes infastructure in the kexec patches that I have
posted to this list serveral times. It sounds like there is probably
some infastructure overlap. I'd like to take a look at what you have
done to see if it fits the needs of kexec so we can avoid code duplication.
Hopefully the size of the kexec patchset can be reduced.
And someone might even review or test it :-)
