Hi,

Since release 1.7.1 and patchset "tailq fully local", the test
eal_flags_autotest doesn't work anymore. It fails because it doesn't
find any free hugepage (rte_memzone_reserve).

The interesting commits are:
	http://dpdk.org/browse/dpdk/commit/?id=e3f3b68c6e42
	http://dpdk.org/browse/dpdk/commit/?id=dd0024ccbc70
The test works only when these patches are reverted.

Here is how to reproduce:
	git revert e3f3b68c6e42
	git revert dd0024ccbc70
	make config T=x86_64-native-linuxapp-gcc
	make
	mkdir -p /mnt/huge
	mount -t hugetlbfs nodev /mnt/huge
	echo 9 > /sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepages
	build/app/test -c 1 -n 1 -m 1
		eal_flags_autotest

I'd like this regression to be fixed for the coming release.
If someone has an idea, he's welcome :)

Thanks
