Quick outline of all changes done as part of this patchset:

* Malloc heap adjusted to handle holes in address space
* Single memseg list replaced by multiple expandable memseg lists
* VA space for hugepages is preallocated in advance

Hi Anatoly,

I haven't looked through your patchset yet but quick question.  As far as I
understand, currently EAL remaps virtual addresses to make VA layout matches PA
layout. I'm not sure my expression is 100% correct.

By your comment above, do you mean VA space for all available physical memory
will always be contiguous?

I have been curious about why VA space is fragmented in DPDK.

Thanks,
