Leif Lindholm 51f375d688 efidisk: Respect block_io_protocol buffer alignment ... Returned from the OpenProtocol operation, the grub_efi_block_io_media structure contains the io_align field, specifying the minimum alignment required for buffers used in any data transfers with the device. Make grub_efidisk_readwrite() allocate a temporary buffer, aligned to this boundary, if the buffer passed to it does not already meet the requirements. Also sanity check the io_align field in grub_efidisk_open() for power-of-two-ness and bail if invalid.		2016-02-27 13:44:59 +01:00
