This change makes struct ifaddr and its variants (in_ifaddr and in6_ifaddr)
MP-safe by using pserialize and psref. At this moment, pserialize_perform
and psref_target_destroy are disabled because (1) we don't need them
because of softnet_lock (2) they cause a deadlock because of softnet_lock.
So we'll enable them when we remove softnet_lock in the future.
The change ensures that ifnet objects in the ifnet list aren't freed during
list iterations by using pserialize(9) and psref(9).
Note that the change adds a pslist(9) for ifnet but doesn't remove the
original ifnet list (ifnet_list) to avoid breaking kvm(3) users. We
shouldn't use the original list in the kernel anymore.
were vaguely useful back when we didn't run make -j, but now you end
up with a single line "done" every so often, with no idea what it is
for. very few other targets claim they're done so just remove these.
drive instead of its associated vfsops. Makes it more friendly, and allows
compat binaries to autoload VFS modules if needed.

gets handled properly even in built-in module case.
XXX
Whatever was I thinking when I put those conditionals in? And wouldn't it
be a wonderful thing to have some atf regression tests to actually catch
errors in the compat{,_sysv} modules? :)
For monolithic kernels, both modules will be compiled as "built-ins",
while modular environments will be able to load the SYSVSEM, SYSVSHM,
and SYSVMSG code independant from the rest of compat.
This is a necessary precursor step to making the "STD" SYSV* code
into a separate module.
Tested in both monolithic and modular environments with no errors
seen.
abuse of pointer to struct mbuf type.
param2 changed to u_long type and uses parameter name 'cmd' (ioctl command)
param3 changed to void * type and uses parameter name 'data'
param4 changed to struct ifnet * and uses parameter name 'ifp'
param5 has been removed (formerly struct lwp *) and uses of 'l' have been
replaced with curlwp from curproc(9).
callers have had (now unnecessary) casts to struct mbuf * removed, called
code has had (now unnecessary) casts to u_long, void * and struct ifnet *
respectively removed.

into separate xxx_ioctl() functions.
* place KASSERT(req != PRU_CONTROL) inside xxx_userreq() as it is now
inappropriate for req = PRU_CONTROL in xxx_userreq().
* replace calls to pr_generic() with req = PRU_CONTROL with pr_ioctl().
* remove & fixup references to PRU_CONTROL xxx_userreq() function comments.
* fix various comments references for xxx_userreq() that mentioned
PRU_CONTROL as xxx_userreq() no longer handles the request.
a further change will follow to fix parameter and naming inconsistencies
retained from original code.

dismantling of pr_usrreq in the protocols; no functional change intended.
PRU_ATTACH/PRU_DETACH changes will follow soon.
Bump for struct protosw. Welcome to 6.99.62!
