| H A D | init_64.c | 8399e4b8 Wed Jul 19 19:12:54 CDT 2017 Nitin Gupta <nitin.m.gupta@oracle.com> 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.
