c993b95329 Fix an off-by-one bug in the CPU and domain ID parser.
The "size" parameter is the size of the corresponding bit set, so the
maximum CPU or domain index is size - 1.

de68a3200a Allow jail names (not just IDs) to be specified for: cpuset(1), ipfw(8),
sockstat(1), ugidfw(8)
These are the last of the jail-aware userland utilities that didn't work
 with names.

e5818a53db Implement several enhancements to NUMA policies.
Add a new "interleave" allocation policy which stripes pages across
domains with a stride or width keeping contiguity within a multi-page
region.

Move the kernel to the dedicated numbered cpuset #2 making it possible
to assign kernel threads and memory policy separately from user.  This
also eliminates the need for the complicated interrupt binding code.

Add a sysctl API for viewing and manipulating domainsets.  Refactor some
of the cpuset_t manipulation code using the generic bitset type so that
it can be used for both.  This probably belongs in a dedicated subr file.

Attempt to improve the include situation.

3f289c3fcf Implement 'domainset', a cpuset based NUMA policy mechanism. This allows
userspace to control NUMA policy administratively and programmatically.

Implement domainset based iterators in the page layer.

Remove the now legacy numa_* syscalls.

Cleanup some header polution created by having seq.h in proc.h.

1de7b4b805 various: general adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

No functional change intended.

WITH_META_MODE we get auto objdir creation, the ability to

Still need to add real targets under targets/ to build packages.

c0ae66888b Create a cpuset mask for each NUMA domain that is available in the
kernel via the global cpuset_domain[] array. To export these to userland,
add a CPU_WHICH_DOMAIN level that can be used to fetch the mask for a
specific domain. Add a -d flag to cpuset(1) that can be used to fetch
the mask for a given domain.

- Add a new -C flag to create a new cpuset and move an existing pid into
 that set.
- Allow 'all' to be specified for a cpu list (e.g. cpuset -s 1 -l all)
 which maps to the list of all CPUs in the system.

413628a7e3 MFp4:
Bring in updated jail support from bz_jail branch.

This enhances the current jail implementation to permit multiple
addresses per jail. In addtion to IPv4, IPv6 is supported as well.
Due to updated checks it is even possible to have jails without
an IP address at all, which basically gives one a chroot with
restricted process view, no networking,..

SCTP support was updated and supports IPv6 in jails as well.

Cpuset support permits jails to be bound to specific processor
sets after creation.

Jails can have an unrestricted (no duplicate protection, etc.) name
in addition to the hostname. The jail name cannot be changed from
within a jail and is considered to be used for management purposes
or as audit-token in the future.

DDB 'show jails' command was added to aid debugging.

Proper compat support permits 32bit jail binaries to be used on 64bit
systems to manage jails. Also backward compatibility was preserved where
possible: for jail v1 syscalls, as well as with user space management
utilities.

Both jail as well as prison version were updated for the new features.
A gap was intentionally left as the intermediate versions had been
used by various patches floating around the last years.

Bump __FreeBSD_version for the afore mentioned and in kernel changes.

Special thanks to:
- Pawel Jakub Dawidek (pjd) for his multi-IPv4 patches
  and Olivier Houchard (cognet) for initial single-IPv6 patches.
- Jeff Roberson (jeff) and Randall Stewart (rrs) for their
  help, ideas and review on cpuset and SCTP support.
- Robert Watson (rwatson) for lots and lots of help, discussions,
  suggestions and review of most of the patch at various stages.
- John Baldwin (jhb) for his help.
- Simon L. Nielsen (simon) as early adopter testing changes
  on cluster machines as well as all the testers and people
  who provided feedback the last months on freebsd-jail and
  other channels.
- My employer, CK Software GmbH, for the support so I could work on this.

cffe6e824b - When running a new command cause cpuset to operate on the per-thread mask
by default rather than the setmask.  This is consistent with the linux
   tool and more consistent with the notion that the default level is
   the process level.  The cpuset mask can still be modified by specifying
   the -c option.  You can not set the per-thread and cpuset mask in
   a single command.
 - Update the man page to reflect this change.

0d985e498d Add a simple utility for manipulating cpusets. Man page will be available
soon.
 - Lists of cpus may be specified with -l with ranges specified as low-high and
   commas between individual cpus and ranges.  ie -l 0-2,4,6-8.
 - cpuset can modified -p pids, -t tids, or -s cpusetids.
 - cpuset can -g get the current mask for any of the above.
