[Bug tapsets/5434] New: Error processing (missing) nfsservctl syscall

When running the following sample command shown in systemtap's web site:

# stap -vv -c df -e 'probe syscall.* { if (target()==pid()) log(name." ".argstr) }'

I get to the following error:

probe sys_vmsplice@fs/splice.c:1475 kernel pc=0xc0000000000ddb74

This is on a PlayStation 3 running Fedora 8, systemtap's sources from the git
repository (as of yesterday) and this kernel:

Linux 2.6.24-rc3 #2 SMP Fri Nov 30 09:51:06 CET 2007 ppc64
ppc64 ppc64 GNU/Linux

It was built by me and it does NOT have CONFIG_NFSD set in it.  If I set this
option in the kernel's configuration, the above command works correctly.
