Log Message:
Hyper-V passes bootstrap entropy to guests via the ACPI OEM0 table.  Use it.

We verify that the OEM0 table has the correct Microsoft IDs, skip the header,
feed the remaining contents to the kernel entropy pool, and wipe them in-place
to prevent later extraction via /dev/acpi (e.g. with acpidump).  This interface
doesn't seem to be documented but we handle it the same way Microsoft's own
Linux driver does.
