Start importing the basic OFED linux compatibility layer changes made by dumbbell@ to be able to compile this layer as a dependency module. Clean up some Makefiles and remove the no longer used OFED define. Currently only i386 and amd64 targets are supported. MFC after: 1 month Sponsored by: Mellanox Technologies

Rename linuxapi[.ko] into linuxkpi[.ko], to reflect that it is a kernel programming interface module, KPI, to avoid confusion with the existing Linux userspace binary compatibility shims. Bump the FreeBSD_version number. Reviewed by: np @ Suggested by: dumbbell @ Sponsored by: Mellanox Technologies

Make the LinuxKPI task struct persistent accross system calls. A set of helper functions have been added to manage the life of the LinuxKPI task struct. When an external system call or task is invoked, a check is made to create the task struct by demand. A thread destructor callback is registered to free the task struct when a thread exits to avoid memory leaks. This change lays the ground for emulating the Linux kernel more closely which is a dependency by the code using the LinuxKPI APIs. Add new dedicated td_lkpi_task field has been added to struct thread instead of abusing td_retval[1]. Fix some header file inclusions to make LINT kernel build properly after this change. Bump the __FreeBSD_version to force a rebuild of all kernel modules. MFC after: 1 week Sponsored by: Mellanox Technologies

Optimise unmapped LinuxKPI page allocations. When allocating unmapped pages, take advantage of the direct map on AMD64 to get the virtual address corresponding to a page. Else all pages allocated must be mapped because sometimes the virtual address of a page is requested. Move all page allocation and deallocation code into an own C-file. Add support for GFP_DMA32, GFP_KERNEL, GFP_ATOMIC and __GFP_ZERO allocation flags. Make a clear separation between mapped and unmapped allocations.

Add support for LinuxKPI tasklets. Tasklets are implemented using a taskqueue and a small statemachine on top. The additional statemachine is required to ensure all LinuxKPI tasklets get serialized. FreeBSD taskqueues do not guarantee serialisation of its tasks, except when there is only one worker thread configured. MFC after: 1 week Sponsored by: Mellanox Technologies

Finish process of moving the LinuxKPI module into the default kernel build. - 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.
