Changes in v5 Rebase to latest code. Changes in v4 Make rte_eal_hugepage_init and rte_eal_hugepage_attach as wrapper functions for BSD. Changes in v3 Changed subject to be more explicit on file name inclusion. Changes in v2 Use common function names rte_eal_hugepage_init and rte_eal_hugepage_attach for BSD and Linux. Update comments about its actuality in function declaration. Changes in v1 Move common functions in eal_memory.c to librte_eal/common/ eal_common_memory.c file. Following functions are moved to eal_common_memory.c file static int rte_eal_memdevice_init(void); int rte_eal_memory_init(void); Fix checkpatch warnings and errors.
