No tools have ever - * been released which used this code, so it's effectively dead. - * - Per Asit Mallick of Intel, added a test for a valid PMBR. - * - Added kernel command line option 'gpt' to override valid PMBR test. - * - * Wed Jun 6 2001 Martin Wilck <Martin.Wilck@Fujitsu-Siemens.com> - * - added devfs volume UUID support (/dev/volumes/uuids) for - * mounting file systems by the partition GUID. - * - * Tue Dec 5 2000 Matt Domsch <Matt_Domsch@dell.com> - * - Moved crc32() to linux/lib, added efi_crc32(). - * - * Thu Nov 30 2000 Matt Domsch <Matt_Domsch@dell.com> - * - Replaced Intel's CRC32 function with an equivalent - * non-license-restricted version. - * - * Wed Oct 25 2000 Matt Domsch <Matt_Domsch@dell.com> - * - Fixed the last_lba() call to return the proper last block - * - * Thu Oct 12 2000 Matt Domsch <Matt_Domsch@dell.com> - * - Thanks to Andries Brouwer for his debugging assistance. - * - Code works, detects all the partitions. - * - ************************************************************/ -#include <linux/crc32.h> -#include <linux/ctype.h> -#include <linux/math64.h> -#include <linux/slab.h> -#include "check.h" -#include "efi.h" - -/* This allows a kernel command line option 'gpt' to override - * the test for invalid PMBR.
