Any news? CONFIG_CHECKPOINT_RESTORE is set for x86_64. It doesn't enable arch-specific code, so it should be safe to set this option for arm too.
Any reason not to set it for all architectures (PPC/s390) too?
I don't see such reasons. JFYI: I am not sure that anyone except CRIU uses checkpoint/restore functionality in kernel. CRIU suports x86_64, ARM, ARM64.
kernel now built with support in F-22 (kernel-3.19.0-0.rc4.git2.1.fc22)
