via-velocity: don't annotate MAC registers as packed
On ARM, memory accesses through packed pointers behave in unexpected ways in GCC releases 4.3 and higher; see https://lkml.org/lkml/2011/2/2/163 for discussion. In this particular case, 32-bit I/O registers are accessed bytewise, causing incorrect setting of the DMA address registers which in turn leads to an error interrupt storm that brings the system to a halt. Since the mac_regs structure does not need any packing anyway, this patch simply removes the attribute to fix the issue. Signed-off-by: Ulrich Hecht <uli@suse.de> Signed-off-by: David S.
