[PATCH 0/5] report allocation stats

[Luc Van Oostenryck <luc.vanoostenryck@gmail.com>]

The goal of this series is to add some support to easily
report allocations statistics and thus be able to do
some experiments about allocation.

For example, playing a bit with this showed that most lists
are quite short (can be as short as and avarage of 2.5 elements
on some code) and that decreasing LIST_NODE_NR from 29 to 13
allow to win 5% when using make C=2 on the kernel (when all
source files have already been compile by GCC), which is already
quite interesting..
