Sparc64 uses some of the upper page->flags bits to store D-cache flushing state. Specifically, PG_arch_1 is used to set whether the page is scheduled for delayed D-cache flushing, and bits 24 and up say which CPU the CPU stores occurred on (and thus which CPU will get the cross-CPU message to flush it's D-cache should the deferred flush actually occur). I imagine that since we don't support the domain stuff (yet) on sparc64, your patches won't break things, but it is something to be aware of. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
