Subject: [PATCH v5 0/3] ACPI: VM fork detection for RNG

Hi Rafael & Len,

This patchset is directed toward you two specifically. Patches 1/3 and
3/3 have been through the ringer of review a bit already and do not
specifically require your attention, but in v4 we wound up getting hung
up on an ACPI API limitation. This v5 fixes that limitation with its 2/3
patch, with a trivial one line fix, which does require your attention.

Patches 1/3 and 3/3 will go through my random.git tree. However, 3/3
actually depends on 2/3 in order to compile without warnings (and be
functional at all). Therefore, it would be nice if you would provide an
"Acked-by" on it and permit me to /also/ take it through my random.git
tree (if it looks like a correct patch to you, of course). This would
make the merge logistics a lot easier. Plus it's a small +1/-1 line
change.

Please have a look and let me know what you think.

Thanks,
Jason
