Thanks, I tried it, and added the missing early_memremap.
But I still got bad values, so I dumped the first 4KB of the table.
It seems to contain events, but they overlap : the last 16 bytes of an
event are overwritten by the following one.
So it seems the UEFI miscalculated the offsets when writing the table,
so gives us data which cannot be used.
