Are there currently any plans to use the hardware page aging bits in the future, and if there are, would architectures that don't have them be required to have them? I'm asking this question because for some time (1.3 onwards), the ARM architecture has had some code to handle software emulation of the young and dirty bits. If its not required, then I'd like to get rid of this software emulation. -- Russell King (rmk@arm.linux.org.uk) The developer of ARM Linux http://www.arm.linux.org.uk/personal/aboutme.html -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
