Cover letter [RFC PATCH 0/3] arm64 initrd mapping/relocation
Quoted 9 lines · Will Deacon

After discussing in linux-efi with Mark, and on #armlinux with Will, this is a proposal for dealing with initrd memory that is potentially not covered by the linear region.
Note that this will look slightly differently when some of the KASLR work gets merged, but this should only affect the way we deal with the initrd if it sits outside of the linear region.

Mostly intended for discussion, not tested at all.
Thanks Ard, this looks like a much better approach to me. Mark -- does the general idea work for you too?
Will
Yeah, much simpler. I like it in concept but am I missing something or is it adding memory to the system beyond the mem= limit? But even that may not be a big deal. And I need to look at the KASLR work and understand the issues with it and mem= if any. I'm traveling right now and can't really try it out until tomorrow...
