Replace them with a common one, placed in types.h. It uses the "packed" flavor of the GUID structs, the alignment attribute is dropped, since it is not required.

I had a quick look into this and the ia64 "related" part ([1]) switches from an `__attribute__ ((aligned(8)))` struct "grub_efi_guid_t" to an `__attribute__ ((packed))` struct "grub_guid_t" (see [2], [3] and below), which might not work as expected on ia64. `include/grub/types.h` defines: ``` #define GRUB_PACKED __attribute__ ((packed)) ``` [1]: https://git.savannah.gnu.org/cgit/grub.git/diff/grub-core/loader/ia64/efi/linux.c?id=06edd40db76bb78457ac26156ed5f7b62381bbe8 [2]: https://git.savannah.gnu.org/cgit/grub.git/diff/include/grub/efi/api.h?id=06edd40db76bb78457ac26156ed5f7b62381bbe8 [3]: https://git.savannah.gnu.org/cgit/grub.git/diff/include/grub/types.h?id=06edd40db76bb78457ac26156ed5f7b62381bbe8 Not sure if it could help to just replace `GRUB_PACKED` with `__attribute__ ((aligned(8)))` for "grub_guid_t" in [3] or if this breaks the cases that originally used "grub_efi_packed_guid_t".
