Looking at the situation, how about proceeding with patch updating
the bootmem API signatures to use phys_addr_t  which can unblock me
to get my machine working.

Introduction of new API, conversions of core kernel code and then
arches moving away from bootmem is going to take significant time
anyways. I will continue my effort to get ARM port moved to no-bootmem
and get that merged.

Let me know how to make progress here. Appreciate your help on the subject.

Regards,
Santosh
