[31/53] ARM: 7204/1: arch/arm/kernel/setup.c: initialize arm_dma_zone_size earlier

[Greg KH]

3.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Arnaud Patard <arnaud.patard@xxxxxxxxxxx>

commit 9811ccdfa94b4773c8030569bd8ec75eafa485ac upstream.

arm_dma_zone_size is used by arm_bootmem_free() which is called by
paging_init(). Thus it needs to be set before calling it.
