Details

Summary

This ioctl would instantly induce a panic, likely since near inception, up
until 0861c7d3e048. Lack of previous interest in fixing it combined with
the problematic interface (exports a pointer, really a physical address)
brings us to the natural conclusion: remove it until a useful consumer
forward.

If it eventually gets resurrected, the interface should definitely not
return in this exact form and likely needs to be reimagined.

The associated KPI, efi_get_table, is left intact for the time being.
