New Revision: 254025
URL: http://svnweb.freebsd.org/changeset/base/254025
Log:
Replace kernel virtual address space allocation with vmem. This provides
transparent layering and better fragmentation.
- Normalize functions that allocate memory to use kmem_*
- Those that allocate address space are named kva_*
- Those that operate on maps are named kmap_*
- Implement recursive allocation handling for kmem_arena in vmem.

Hello Jeff,
I'm having some trouble on my ARM platform staring from this commit.
Kernel panics on assertion very early. Please check out log below (as
you can see bt doesn't look helpful but assertion message is visible. I
can send you which functions are in bt if it is necessary).
It would be very helpful to know which function is passing the unaligned
value. I will resolve this later today if you can get me that
information.
Thanks,
Jeff
Best regards
Zbyszek Bodek
