Hi,
Quick note: the Internet has just returned back here after a full
5-day shutdown by the “authorities”. I will hopefully return back
home on Saturday to continue working on this.

When restarting using the kernel kexec functionality the MMU
needs to be turned off. Any code which does this needs to use
identity mapped addresses to get reliable results. In the ARM
kexec case this identity mapping is done:
- using the page table of the current task
- for all addresses normall
