This patch introduces ipcs storage into IDRs. The main changes are:
. This ipc_ids structure is changed: the entries array is changed into a
root idr structure.
. The grow_ary() routine is removed: it is not needed anymore when adding
an ipc structure, since we are now using the IDR facility.
. The ipc_rmid() routine interface is changed:
. there is no need for this routine to return the pointer passed in as
argument: it is now declared as a void
. since the id is now part of the kern_ipc_perm structure, no need to
have it as an argument to the routineSigned-off-by: Nadia Derbey

This patch provides the following hugetlb-related fixes to the recent stacked
shm files changes:
- Update is_file_hugepages() so it will reconize hugetlb shm segments.
- get_unmapped_area must be called with the nested file struct to handle
the sfd->file->f_ops->get_unmapped_area == NULL case.
- The fsync f_op must be wrapped since it is specified in the hugetlbfs
f_ops.This is based on proposed fixes from Eric Biederman that were debugged and
tested by me. Without it, attempting to use hugetlb shared memory segments
on powerpc (and likely ia64) will kill your box.Signed-off-by: Adam Litke

Add SHM_NORESERVE functionality similar to MAP_NORESERVE for shared memory
segments.This is mainly to avoid abuse of OVERCOMMIT_ALWAYS and this flag is ignored
for OVERCOMMIT_NEVER.Signed-off-by: Badari Pulavarty

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.Let it rip!
