260194052e Reduce memory consumption when allocating kobject strings in the
LinuxKPI. Compute string length before allocating memory instead of
using fixed size allocations. Make kobject_set_name_vargs() global
instead of inline to save some bytes when compiling.

9782763db2 In the zero delay case in queue_delayed_work() use the return value
from taskqueue_enqueue() instead of reading "ta_pending" unlocked and
also ensure the callout is stopped before proceeding.

86845417d1 Build fixes:
- Add some missing I/O functions for non-i386 and amd64 platforms.
- Stub ioremap() to NULL using a macro to ensure non-existing memory
  attributes are not referred when they do not exist.
- Add more header files to linux/list.h to resolve driver compilation
  issues on Sparc64 and PowerPC platforms.

3b383c9ede linuxkpi/sysfs.h: Cast arg2 through intptr_t to avoid GCC warning
The code compiles fine under Clang, but GCC on PPC is less permissive about
integer and pointer sizes.  (An intmax_t is clearly *large enough* to hold a
pointer value.)

Another follow-up to r290475.

8d59ecb214 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.
