iommu/arm-smmu-v3: Fix compilation when CONFIG_CMA=n
When compiling a kernel without support for CMA, CONFIG_CMA_ALIGNMENT
is not defined which results in the following build failure:
In file included from ./include/linux/list.h:9:0
from ./include/linux/kobject.h:19,
from ./include/linux/of.h:17
from ./include/linux/irqdomain.h:35,
from ./include/linux/acpi.h:13,
from drivers/iommu/arm-smmu-v3.c:12:
drivers/iommu/arm-smmu-v3.c: In function ‘arm_smmu_device_hw_probe’:
drivers/iommu/arm-smmu-v3.c:194:40: error: ‘CONFIG_CMA_ALIGNMENT’ undeclared (first use in this function)
#define Q_MAX_SZ_SHIFT (PAGE_SHIFT + CONFIG_CMA_ALIGNMENT)
Fix the breakage by capping the maximum queue size based on MAX_ORDER
when CMA is not enabled.
