Default branch: MAIN

Simplify sys/compat/sys/sockio.h. No functional change intended.

 - Move some definitions from sys/compat/sockio.h to compat/net/if.h.
   struct oif_data in sockio.h and if_data50 are the same, so remove oif_data.
   Do the same thing to oifdatareq, too.
 - u_quad_t -> uint64_t. No functional change.

Don't reference ifp->if_data directly; use if_export_if_data().

Remove clause 3 and 4 from TNF licenses.
Ok'ed by martin@ in PR/54760.

Remove clause 3 and 4 leftovers from TNF licenses in more sources.
Confirmed by martin@ in PR/54760.

Remove clause 3 and 4 leftovers from TNF licenses in more sources.

Confirmed by martin@ in PR/54760.

Rather than keeping a separate mutex, condvar, and pserialize for each
module hook, we can share a common set of synchronization structures.
This cuts the amount of cacheline_aligned data for these structures by
50%.

Note that we still have a per-hook localcount, since we need to count
individual references.

As discussed with riastradh@

Welcome to 9.99.22 !

Sync with HEAD

Rename the MODULE_*_HOOK() macros to MODULE_HOOK_*() as briefly
discussed on irc.

NFCI intended.

Ride the earlier kernel bump - it;s getting crowded.

Merge the [pgoyette-compat] branch

Convert the macros for setting and unsetting a hook to generate
in-line code rather than using an intermediary hook##set routine.
Hooks are set and unset only in one place, so the intermediary
routine provides no benefit.  IMHO using the macro at the point-
of-call is more readable than using it elsewhere in the code and
then calling the generated intermediary routine (for which you
won't even find its declaration or definition unless you remember
to search for the HOOK_SET macro instead).

NFC intended, will verify with a bulk build and an atf test run.

Convert a couple more hooks to the MP-safe mechanism.

While here, clean up some headers and remove any that are now empty.

Ssync with HEAD

#include "opt_compat_netbsd.h" for all sources that provide compat code.

Use the MP-safe hooks mechanism for the uipc_syscalls_40 and _50
routines.

 Fix a bug that SIOC[GZ]IFDATA returned old ifreq structure.

Synch with HEAD

Import rev 1.5 from HEAD

Test for valid interface for ioctls that demand it.

Thanks to Robert Swindells for the patch.

Rename if_[45]0_{init,fini} entry points to more appropriate and more
consistent uipc_syscalls_[45]0_{init,fini} and remove some multiple
declarations.

Sync with HEAD, resolve some conflicts

Merge christos's recent changes on HEAD

provide vectors for the ifconf compat code and ifdatareq compat code.

Remove unnecessary conditionals.  These files aren't built unless
their content is needed (via config option or module configuration).

Clean up compat routine vectors

Implement vector initialization for ifreqo2n and ifdatareq

Sync with HEAD.

sync with head

Remove includes <sys/mount.h> and <sys/sched.h> added for <sys/syscallargs.h>.
Now they are handled by $sysarghdrextra in sys/kern/syscalls.conf.
