I discussed this shortly with Sascha yesterday and we agree the core serializes requests to the host (by means of mmc_claim_host and synchronus requests). Protecting only the interrupts works for drivers like pxa and mxc. Such locking might or might not be not enough for sdhci, but that would have to be carefully evaluated. Should be worth trying, though (unless we missed something).
