Since these patches are all the same, and they have identical subject and description texts, I would suggest combining them into a single patch to keep the series more compact. Having them separate would allow merging the patches through the individual architecture maintainer trees, but that in turn would mean waiting longer to get it all merged, but in this case it seems way easier to go through the asm-generic tree.
