Currently the lnet headers used for user land applications
contain various kernel definations. This is due to the
fact libcfs contains kernel wrappers for user land which
will be going away. This patch sorted the header data
so all kernel containing structures are moved out of
headers that user land will use.

This is broken out of the original patch 12932 that was
merged to the Intel/OpenSFS branch.

1.7.1
From: John L. Hammond <[email protected]>
Originally socklnd_lib-linux.h contained linux specific
wrappers and defines but since the linux kernel is the
only supported platform now we can merge what little
remains in the header into socklnd.h. This is broken
out of the original patch 12932 that was merged to the
Intel/OpenSFS branch.

1.7.1
Currently several special macros LNet NID macros exist
in libcfs.h and libcfs_private.h. Move those macros
out to the lnet header types.h. The new lnet header
nidstr.h contains LNet NID string data that can be
used by user land LNet utilities and the LNet kernel
drivers.

Currently the lnet headers used by user land contain various internal
LNet structures that are only used by kernel space. Move the user land
structures to headers used by user land. The kernel structures are
relocated to headers that are never exposed to user land.

Fixing it inside arch/m68k/include/asm/irq.h might cause Include Hell,

Hi Geert,
I have not tested it, but I think the following may fix the problem
while avoiding any include problems. Since pt_regs is used in the file,
one could argue that it should be declared.
Thanks,

... asmlinkage and atomic_t are also needed.
I didn't want to risk introducing more breakage by adding (at least) three
more includes.

Hi Geert
Long time. I agree the above is not the best approach. Lets fix lustre instead.
