can the fix be applied at least to 14.04 lts kernels as well?
It should just be adding a build depends as I can build a correct perf just
fine on a stock 14.04 with the right dependencies (libbfd-dev I think is the
missing one)

tool now works again and is still demangling c++ symbols correctly.
eztrace also starts but I did not test its functionality.

@Todd
are you sure they are not swappable?
according to lwn they are:
http://lwn.net/Articles/423584/
"""
This scheme will increase the use of huge pages transparently, but it does not
yet solve the whole problem. Huge pages must be swappable, lest the system run
out of memory in a hurry. Rather
I know non-anonymous huge pages, like those from hugetblfs, are currently not
swappable.
But if I understand the article correctly _anonymous_ huge pages can be swapped.
You lose the benefits of huge pages in this case (as they are split) but the
system does not regress in functionality.
