This is the updated patchkit to allow to use 1GB pages for mmap/shmget directly. This is needed for various software and makes it far more convenient to use 1GB pages.
There were a lot of discussions on the ABI of v6 due to a conflict of the new bits with the NOMMU only feature MAP_UNINITIALIZED.
However I don't think this matters at all because this feature only works with HUGETLBFS and HUGETLBFS and NOMMU are mutually exclusive. So any architecture which suppors HUGETLBFS will never do MAP_UNINITIALIZED and vice versa. So there's no actual conflict in these flags.
Based on that I don't think any changes are needed.
So I decided to just repost with a rebase.
Please consider applying,
Thanks, -Andi
