RE: [PATCH] remove unimplemented syscalls noise

Well, in the case of unaligned faults, there is no other way for an
application to know that there were unaligned faults.  Whereas for
unsupported system calls, the kernel will return ENOSYS and thus the
application gets the required notification (so that it can take any
action it wants).  It does not need to depend on dmesg stuff to find
that information out.  

So, it does make sense to remove this printk (even though it is _debug_)
in this path.
