XFS on UltraSparc

[Jim Crilly <noth@noth.is.eleet.ca>]

I have Debian unstable running on a UltraSparc1 and I wanted to see if I could 
get XFS working on it which went ok. This isn't really a XFS specific question, 
so keep reading =)

The filesystem itself works, but I felt ambitious and wanted to get ACLs and 
EAs working from userspace, from what the XFS developers told me all I should 
have to do is add syscall numbers for the appropriate architecture. I also 
think I got this working right, but I had a few questions.

1) Since I'm running on an UltraSparc do I need to touch the files in 
arch/sparc or just arch/sparc64? Same for include/asm-sparc and include/asm-
sparc64?

2) I add the syscall entries to include/asm-sparc64/unistd.h and 
arch/sparc64/kernel/systbls.S and update NR_SYSCALLS in 
arch/sparc64/kernel/entry.S and I should be done right?

The only real problem I'm running into is some of the utilities, like 
xfs_repair are getting SBus errors, any tips on trying to clear these up? 

Thanks,
   Jim
