ARM: mm: fix type of the arm_dma_limit global variable
arm_dma_limit stores physical address of maximal address accessible by DMA, so the phys_addr_t type makes much more sense for it instead of u32. This patch fixes the following build warning: arch/arm/mm/init.c:380: warning: comparison of distinct pointer types lacks a cast Reported-by: Russell King <linux@arm.linux.org.uk> Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com>
