sparc64: Register hugepages during arch init
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. Orabug: 25869946 Reviewed-by: NBob Picco <bob.picco@oracle.com> Signed-off-by: NNitin Gupta <nitin.m.gupta@oracle.com> Signed-off-by: NDavid S.
