Cover letter [RFC PATCH 0/3] arm64 initrd mapping/relocation
Quoted 8 lines · Ard Biesheuvel
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.
Quoted 6 lines
Mostly intended for discussion, not tested at all.
Ard Biesheuvel (3):
memblock: add routine to clear theMEMBLOCK_NOMAPflag for a region
arm64: add the initrd region to the linear mapping explicitly
arm64: remove the now unneededrelocate_initrd()
I discovered the original problem on AMD Seattle and these patches fixed it for me.
