This set of four patches moves XPC and XPNET to drivers/misc/sgi-xp in
preparation for enabling SGI UV X86_64 support.
This version is prompted by reported build problems with certain configs,
and a desire to keep things simple by only moving XPC/XPNET as is and
only addressing Lindent and checkpatch.pl issues (not x86_64 issues) at
this time.
