And this is where I think the problem is, in particular the align field
for the LOAD headers.

aarch64-linux-gnu-readelf -Wl /lib/systemd/systemd

Elf file type is DYN (Shared object file)
Entry point 0x2c8d0
There are 10 program headers, starting at offset 64

Program Headers:
  Type           Offset   VirtAddr           PhysAddr           FileSiz  MemSiz   Flg Align

Title:
  Systemd init failure on arm64 64k pages

Status in systemd package in Ubuntu:

Bug description:
  Some binaries in 15.10 for aarch64 seem to be compiled with maxpagesize=4K which triggers issues when run on 64K pages
  arm64 kernels (tested on all kernels back to 4.0). I spotted this while trying to boot an arm64 kernel with 64K pages enabled on 15.10 Ubuntu filesystem.
