Since BOOTMEM_LOW_LIMIT is hardwired to 0 there is no restrictions on where the allocated memory should reside. The memblock_alloc_nopanic(size, PAGE_SIZE) also allocates PAGE_SIZE aligned memory without any restrictions and thus can be used as a replacement for alloc_bootmem_pages_nopanic() Signed-off-by: Mike Rapoport Acked-by: Michal Hocko --- drivers/usb/early/xhci-dbc.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/usb/early/xhci-dbc.c b/drivers/usb/early/xhci-dbc.c index e15e896..16df968 100644 --- a/drivers/usb/early/xhci-dbc.c +++ b/drivers/usb/early/xhci-dbc.c @@ -94,7 +94,7 @@ static void * __init xdbc_get_page(dma_addr_t *dma_addr) { void *virt; - virt = alloc_bootmem_pages_nopanic(PAGE_SIZE); + virt = memblock_alloc_nopanic(PAGE_SIZE, PAGE_SIZE); if (!virt) return NULL; -- 2.7.4
