[CRIU] Criu illegal instruction on ARM6 (Raspberry Pi zero) ...

[Mark O'Neill]

Hello

I don't know if I have come through to the right place.

I am trying to build criu 3.15 for Raspberry Pi zero. Compilation from
source is fine but restorer.c generates an illegal instruction when criu
is run. I have checked your makefile and it seems to be detecting ARM6
architecture okay. Not sure how to proceed. The error occurs at in
restorer.c at this point:

I have highlighted the ARM instruction which is throwing the error.
