>So Is 64 bit "user-space appls" the same as 64 bit kernal?
No.
64bit-kernel : kernel uses 64bit for integers (f.e.)
64bit app : applications use 64bit for integers (f.e.)
If you see the kernel as an application, its the same. The kernel is not
that much different from an app, its just not running as a process and
in a different environment.
All this is only part of the picture. You could write a book about
32+64bit.
F.e. are arguments to syscalls 32 or 64bit? What about libraries? Can
your filesystem use 64bit filehandles (must be large-file enabled)? Can
your processor handle 64bit? If yes, only address or also data? etc.etc.
