I don't know where you get that idea from. What it does is make a kernel built with a standard set of options have differing behaviour on v7 and pre-v7 architectures. On v7 architectures, the vectors page and user pages all become read only to SVC mode. On pre-v7 architectures on the same kernel, they are read- write to SVC mode. What we have now is that these pages are only read-only when CPU domains are turned off - for everything. So we know that if CPU domains are enabled, it's read/write, otherwise it's read only. That's more straight forward than what this patch creates IMHO. -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
