memblock, bootmem: restore goal for alloc_low
Now we have memblock_virt_alloc_low to replace original bootmem api in swiotlb. But we should not use BOOTMEM_LOW_LIMIT for arch that does not support CONFIG_NOBOOTMEM, as old api take 0. | #define alloc_bootmem_low(x) \ | __alloc_bootmem_low(x, SMP_CACHE_BYTES, 0) |#define alloc_bootmem_low_pages_nopanic(x) \ | __alloc_bootmem_low_nopanic(x, PAGE_SIZE, 0) and we have #define BOOTMEM_LOW_LIMIT __pa(MAX_DMA_ADDRESS) for CONFIG_NOBOOTMEM. Restore goal to 0 to fix ia64 crash, that Tony found.
