Changes in this version are described in the patches, in short:
v2:
- use real memory as WABB destination,
- address CI compains - do not decrease vm.total,
- minor reordering.
v3:
- fixed typos,
- removed spare defs,
- added tags
v4:
- removed NULL PTE patch,
- separate selftest to separate patch,
- use BB only on BCS0
v5:
- fixed reserved memory allocation
v6:
- decresase vm->total by reserved size

Regards
Andrzej
