Subject: ARM: mm: change further appearance of arm_dma_zone_size to phys_addr_t
The definition was chagned in commit 364230b995214 ("ARM: use phys_addr_t
for DMA zone sizes").
Fixes this build error:
arch/arm/mm/init.c:199:13: error: conflicting types for 'arm_dma_zone_size'
include/linux/bootmem.h:259:11: note: previous declaration of 'arm_dma_zone_size' was here
While changing the type, we also need to limit MAX_DMA_ADDRESS if
PAGE_OFFSET + arm_dma_zone_size is greater than 4GB. The MAX_DMA_ADDRESS
is a virtual address and we really don't want the 32-bit value of this
wrapping.
