Forgot to mention that there is a checkpatch warning:
WARNING:LONG_LINE: line over 90 characters
#113: FILE: lib/librte_eal/linuxapp/eal/eal_memory.c:1167:
+               qsort(&tmp_hp[hp_offset], hpi->num_pages[0], 
sizeof(struct hugepage_file), cmp_physaddr);

Could you fix that Ralf?

Thanks,
Sergio
