Yishai Hadas 89dd86db78 mlx4_core: Allow large mlx4_buddy bitmaps ... mlx4_buddy_init uses kmalloc() to allocate bitmaps, which fails when the required size is beyond the max supported value (or when memory is too fragmented to handle a huge allocation). Extend this to use use vmalloc() if kmalloc() fails, and take that into account when freeing the bitmaps as well. This fixes a driver load failure when log num mtt is 26 or higher, and is a step in the direction of allowing to register huge amounts of memory on large memory systems.
