and maybe add a one-line mc_channel_to_global_intstatus(mc, channel) helper

mc_ch_writel(mc, MC_BROADCAST_CHANNEL,
	     mc_channel_to_global_intstatus(mc, chan), 
	     MC_GLOBAL_INTSTATUS);

Missing braces after "else", "./scripts/checkpatch.pl --strict" should warn about this.

Otherwise this patch looks okay at a quick glance.
