From: Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx>
Subject: include/linux/efi.h: redefine type, constant, macro from generic code
Generic UUID library defines structure type, macro to define UUID, and the
length of the UUID string. This patch removes duplicate data structure
definition, UUID string length constant as well as macro for UUID
handling.
