Christoph Hellwig 0895708c5c FROMGIT: net: Revert "net: optimize the sockptr_t for unified kernel/user address spaces" 
This reverts commits 6d04fe15f7 and
a31edb2059.

It turns out the idea to share a single pointer for both kernel and user
space address causes various kinds of problems.  So use the slightly less
optimal version that uses an extra bit, but which is guaranteed to be safe
everywhere.
