This can work - For 64 CPUs e.g. R4k and up it is common to run a 64Bit
kernel and a 32Bit userspace.
E.g.
[EMAIL PROTECTED]:~$ file /bin/bash
/bin/bash: ELF 32-bit MSB executable, MIPS, MIPS-I version 1 (SYSV), for
GNU/Linux 2.4.0, dynamically linked (uses shared libs), for GNU/Linux
2.4.0, stripped
[EMAIL PROTECTED]:~$ uname -a
Linux reset 2.6.9-rc2 #8 Fri Sep 24 17:23:43 CEST 2004 mips64 GNU/Linux
I guess xfsdump/restore use some interesting ioctl's which might
need compat wrappers for the 32/64 bit case. But this is how its
supposed to work.
