This series implements non-contiguous trace buffers.
Please review.

For some reason its not possible to allocate more than 128MB with repeated
calls to alloc_xen_heappage(). Any ideas how to reach the theoretical limit of
256MB per cpu?
Also the error path in alloc_trace_bufs() needs a fix, I always run into the
assert there.

Olaf
