GNU/Linux isn't: Linux=GPLv2, GNU=GPLv3+, they can't share code.
Either it's "mere aggregation", or a license violation.  Pick one.

I took a closer look at the arch/um code, and it wasn't as hard as I
thought.  I have a proposed set of patches to completely remove
IRQF_SAMPLE_RANDOM that I will be sending out shortly....

I'll happily test them, please CC me.

BTW: On UML we have anyway CONFIG_UML_RANDOM to get good random numbers.
It reads from thes host's /dev/random.
