Bug#281905: please enable CONFIG_EFI_PARTITION; it's needed for > 2TiB

[Tore Anderson <tore@debian.org>]

  I second this request.  GPT is in my opinion superior to the MSDOS
 partition-table type, for several reasons like robustness (no fragile
 linked list of extended partitions, backup partition table),
 flexibility and of course scalability, the reason why Mr. DeRobertis
 wanted it.

  As he also points out, it works and is useful on normal ia32 hardware
 (in spite of what fs/partitions/Kconfig says).

  I must admit I cannot comment on the potential issues with broken USB
 devices, as I don't have such hardware in my possession.  It does
 strike me as odd, though, that there is a problem:  As I understand it
 the GPT detection code fails if it doesn't find a valid "Protective
 MBR", ie. a MSDOS partition table with one partition, spanning the
 whole drive, with the type set to 0xEE.  Am I wrong assuming that such
 a partition table will almost certainly never be found on such a broken
 USB device that doesn't have a GPT, and thus there should be no
 problem?

  See also the documentation for the 'gpt' kernel parameter in
 Documentation/kernel-parameters.txt.

  Finally I'd like to point out that SuSE do indeed support GPT in their
 ES¹ 9 product, so there must obviously be some way to enable it without
 USB breakage ensuing.
