We don't support non-realtime signals (the syscalls are rt_*)

umount2

newselect

obsolete

we don't use the socketcall multiplexer (presumably because we don't need
to put the args on the stack) for socket/bind/connect/ etc...

same story as socketcall, obsolete multiplexed syscall

sys_fadvise64_64 versus fadvise64 is a reordering of syscall args, presumably
because loff_t is 64bit and needs to be passed in pairs.

Your kernel is too old. 2.6.21-rc3 has this.

Dunno about this one. sys_utimes seems to just call futimesat anyways.

nobody's implemented kexec yet. :)
