OK, I've pulled these patches out. For the MMC issue I suggest using ifdef CONFIG_PPC and mfspr(SPRN_SVR) like the clock driver does[1] and we can revisit the issue if/when we need to do something similar on an ARM chip. -Scott [1] One of the issues with Arnd's approach is that it wouldn't have worked for early things like the clock driver, and he didn't seem to mind using ifdef and mfspr() there. -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
