From: Yinghai Lu <yinghai@xxxxxxxxxx>
Subject: 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.
