aargh.  Any time anyone dinks with the syscall tables I have tons of fun
fixing up rejects.  It doesn't help that both Stephane and Christoph's
patches were fairly broken.

Rules:

a) Keep unistd.h and the syscall tables in sync.

b) Keep ppc32 and powerpc[64] in sync

c) Add prototypes to syscalls.h (When the implementation goes in -
   obviously not relevant when we're just reserving syscall slots)

d) Some architectures have multiple syscall tables.  Stephane, you
   missed arch/ia64/ia32/ia32_entry.S, for example.  But then, that looks
   to be seriously out of date anyway.  No idea what's going on there.

e) review your work carefully.  Grep the tree for, say, `getxattr' (or
   any other syscall name which is unique-looking and which you expect all
   architectures to implement).

Anyway, I have a shower of fixup patches here.   Hopefully it all landed OK.
