    [IA64] 4-level page tables · 837cd0bd
    Robin Holt 提交于
    This patch introduces 4-level page tables to ia64.  I have run
    some benchmarks and found nothing interesting.  Performance has
    consistently fallen within the noise range.
    
    It also introduces a config option (setting the default to 3
    levels).  The config option prevents having 4 level page
    tables with 64k base page size.
