    sparc64: Register hugepages during arch init · 8399e4b8
    Nitin Gupta 提交于
    Add hstate for each supported hugepage size using
    arch initcall. This change fixes some hugepage
    parameter parsing inconsistencies:
    
    case 1: no hugepage parameters
    
     Without hugepage parameters, only a hugepages-8192kB entry is visible
     in sysfs.  It's different from x86_64 where both 2M and 1G hugepage
     sizes are available.
    
    case 2: default_hugepagesz=[64K|256M|2G]
    
     When specifying only a default_hugepagesz parameter, the default
     hugepage size isn't really changed and it stays at 8M. This is again
     different from x86_64.
