SMbios is important for server hardware vendors. It implements a spec for
providing descriptive information about the platform. Things like serial
numbers, physical layout of the ports, build configuration data, and the like.

This has been tested by dmidecode and lshw tools.

It turns out that efi_lookup_mapped_addr() is not appropriate after all for
remapping the address of the SMBIOS tables. The reason is that the UEFI spec
forbids virtual mappings being requested for configuration tables (which is not
currently honored by Tianocore/EDK2)

@Yi: could you retest yet again, please?

@Will; this superseded the patch that is already queued up in
for-next/core, so perhaps you could drop that while we get this
tested?

Reverted. I'd really appreciate help testing this stuff in future -- it was
a pig getting it going on the foundation model and the whole setup felt
rather contrived.

Anyway, thanks for letting me know.

Hi Will,

Are you ok to take this patch now, for 3.18? Surely, we could get it
tested today or tomorrow if you would still like do it yourself? Yi
has tested it on a recent RC so we could ask him to demonstrate if for
us.

Cheers,
Ard.
