Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[DECnet]: Endian annotation and fixes for DECnet. The typedef for dn_address has been removed in favour of using __le16 or __u16 directly as appropriate. All the DECnet header files are updated accordingly. The byte ordering of dn_eth2dn() and dn_dn2eth() are both changed since just about all their callers wanted network order rather than host order, so the conversion is now done in the functions themselves. Several missed endianess conversions have been picked up during the conversion process. The nh_gw field in struct dn_fib_info has been changed from a 32 bit field to 16 bits as it ought to be. One or two cases of using htons rather than dn_htons in the routing code have been found and fixed. There are still a few warnings to fix, but this patch deals with the important cases.
