[PATCH] GUID Partition Tables for 2.4.x

Marcelo and Alan:

Posted to http://domsch.com/linux/patches/gpt is the GUID Partition Table 
code, copied from the IA64 port patch and applied to 2.4.19-pre1 and 
2.4.19-pre10-ac2.  This code is identical to that included in the IA64 
port patch already, and has been in use on IA64 for many many months.  
Equivalent code is already included in the 2.5 kernel series.  I'm 
submitting now for 2.4.x so that a partition table scheme which supports 
Large Block Devices will be available if/when Peter Chubb's work on such 
is backported from 2.5.x.  I've tested this on x86.

The work consist of two parts:
1) Changes efi_guid_t typedef to match the 2.5.x implementation.  This 
code is already included in the ia64 port patch for 2.4.x, and I have 
David Mosberger's approval to submit this directly for 2.4.x.

2) Adds fs/partitions/efi.[ch] and associated small changes to related 
files.  The arch/ia64/defconfig change removes a stale entry.

Marcelo, I understand you won't wish to apply this before 2.4.19 final.  I 
don't expect any conflicts to arise between this code and anything 
expected in 2.4.19 final, so please try to apply this after 2.4.19 is out.

Thanks,
Matt
