- Move all files related to the LinuxKPI into sys/compat/linuxkpi and its subfolders. - Update sys/conf/files and some Makefiles to use new file locations. - Added description of COMPAT_LINUXKPI to sys/conf/NOTES which in turn adds the LinuxKPI to all LINT builds. - The LinuxKPI can be added to the kernel by setting the COMPAT_LINUXKPI option. The OFED kernel option no longer builds the LinuxKPI into the kernel. This was done to keep the build rules for the LinuxKPI in sys/conf/files simple. - Extend the LinuxKPI module to include support for USB by moving the Linux USB compat from usb.ko to linuxkpi.ko. - Bump the FreeBSD_version. - A universe kernel build has been done.
