Yishai Hadas 3de819e6b6 mlx4_core: Fix integer overflow issues around MTT table ... Fix some issues around int variables used in data structures related to memory registration. Handle int overflow in mlx4_init_icm_table by using a u64 intermediate variable and changing struct mlx4_icm_table num_obj field to be u32. Change some more fields/variables to use u32 instead of int to prevent a case where the variable becomes negative when bit 31 is set. Also subtract log_mtts_per_seg from the exponent when computing num_mtt, since its added later on in that very same code area. This and the previous commit fixes some issues which actually prevent commit db5a7a65c0 ("mlx4_core: Scale size of MTT table with system RAM") from working. Now, when the number of MTTs is scaled with the size of the RAM we can map up to 8TB.
