Ah yes, I see what you mean.

Hopefully microMIPS support is new enough for that not to matter.

It appears that the restart behaviour was improved in v2.6.36 in commit
8f5a00eb422e ("MIPS: Sanitize restart logics"), whereas first mentions
of micromips are in v3.9, in commit f8fa4811dbb2 ("MIPS: Add support for
the M14KEc core.").
