the !COMPAT_43 case - use a common function even when there is no
`old' function. The diffs for this are large because of code motion
to restore the function order to what it was before the pseudo-argument
changes.
Include <sys/sysproto.h> to get correct args structs and prototypes.
The diffs for this are large because the declarations of the args structs
were moved to become comments in the function headers. The comments may
actually match the automatically generated declarations right now.
Add prototypes.
Instead of using a fake "compat" argument, pass a real compat int to function
if COMPAT_43 is defined. Functions involved: wait4, accept, recvfrom,
getsockname.
With the compat psuedo-argument, this introduces an argument structure
that can have two possible sizes depending on compat options.
This makes life difficult for lkm modules like ibcs2, which would
have to guess what size used in kernel when compiled. Also,
the prototype generator for these structures cannot generate proper sizes.
Now there is only one fixed structure and makes everybody happy.
I recommend these changes be introduced to 2.1 so that ibcs2, linux
lkm's generated for 2.2 can still run on a 2.1 kernel.
