From: Brian Behlendorf <behlendorf1@llnl.gov>
Subject: [PATCH] linux kernel module
Subject: [PATCH] linux have xdr
Setup linux kernel module support, this includes:
- zfs context for kernel/user
- kernel module build system integration
- kernel module macros
- kernel module symbol export
- kernel module options
Use XDR if HAVE_XDR defined
