EXPORT_SYMBOL's do nowadays belong to the files where the actual

Moving the module_init/module_exit to the file with the actual functions

The PPTP NAT helper calculates the offset at which the packet needs
to be mangled as difference between two pointers to the header. With
non-linear skbs however the pointers may point to two seperate buffers
on the stack and the calculation results in a wrong offset beeing
used.

We're starting a number of big applications (memory footprint app.
1MByte) on our Arcturus uC5272.  Therefore memory fragmentation is a
real pain for us.  We've switched to uClinux-2.4.27-uc1 and found that
page_alloc2 fragments the memory heavily.

Digging into it we found a bug in the find_next_zero_bit function in the
m68knommu/bitops.h file.  if the size isn't a multiple of 32 than the
upper bits of the last word to be searched should be masked.  But the
functions masks the lower bits of the last word because it uses a right
shift instead of a left shift operator.

Modify the initial trace output (which is based on flags in the binary
header) so that it is not done until after the magic number check.  This
may well not be a flat format binary, so the flags could be invalid.

This is a patch adapted from a posting by Andrea Tarani which was
pointed out to me by Bernardo Innocenti.  Thanks to both of them for
their help and patience.

The original posting is here:
  http://mailman.uclinux.org/pipermail/uclinux-dev/2005-July/033543.html

The problem first manifest itself as busybox ping terminating with an
"Illegal instruction".  I reduced this to a test case and found that
variable size arrays allocated on the stack could lead to stacks not
aligned on 32 bit boundaries.  For the Coldfire this proved fatal.

Having been pointed out this patch by Bernardo, I applied it and it
fixed the first test case.  I then went back to busybox's ping.  This
still failed with "Illegal instruction", but in a different way.  Before
it depended on the size allocated for the ping buffer, now it happened
every time.  I also found it depended on optimisation level (gcc-3.4.0)
-Os was okay but not -O2.

After a lot of looking, it turned out that register a5 was being
corrupted by the signal handler (after applying the patch).  I re-worked
the patch a bit to save/restore a5 and now all seems well.
