o Make the pfsync.ko actually usable. Before this change loading it
didn't register protosw, so was a nop. However, a module /boot/kernel
did confused users.
o Rewrite the way we are joining multicast group:
- Move multicast initialization/destruction to separate functions.
- Don't allocate memory if we aren't going to join a multicast group.
- Use modern API for joining/leaving multicast group.
- Now the utterly wrong pfsync_ifdetach() isn't needed.
o Move module initialization from SYSINIT(9) to moduledata_t method.
o Refuse to unload module, unless asked forcibly.
o Improve a bit some FreeBSD porting code:
- Use separate malloc type.
- Simplify swi sheduling.
This change is probably wrong from VIMAGE viewpoint, however pfsync
wasn't VIMAGE-correct before this change, too.

destroyed prior to pfsync_uninit(). To do this, move all the
initialization to the module_t method, instead of SYSINIT(9).
o Fix another panic after module unload, due to not clearing the
m_addr_chg_pf_p pointer.
o Refuse to unload module, unless being unloaded forcibly.
o Revert the sub argument to MODULE_DECLARE, to the stable/8 value.
This change probably isn't correct from viewpoint of VIMAGE, but
the module wasn't VIMAGE-correct before the change, as well.

The C11 folks reinvented the wheel by introducing an aligned version of
malloc(3) called aligned_alloc(3), instead of posix_memalign(3). Instead
of returning the allocation by reference, it returns the address, just
like malloc(3).

The vfs_busy() is after covered vnode lock in the global lock order, but
since quotaon() does recursive VFS call to open quota file, we usually
end up locking covered vnode after mp is busied in sys_quotactl().
Change the interface of VFS_QUOTACTL(), requiring that mp was unbusied
by fs code, and do not try to pick up vfs_busy() reference in ufs quotaon,
esp. if vfs_busy cannot succeed due to unmount being performed.

operation on POSIX shared memory objects and tmpfs. Previously, neither of
these modules correctly handled the case in which the new size of the object
or file was not a multiple of the page size. Specifically, they did not
handle partial page truncation of data stored on swap. As a result, stale
data might later be returned to an application.
Interestingly, a data inconsistency was less likely to occur under tmpfs
than POSIX shared memory objects. The reason being that a different mistake
by the tmpfs truncation operation helped avoid a data inconsistency. If the
data was still resident in memory in a PG_CACHED page, then the tmpfs
truncation operation would reactivate that page, zero the truncated portion,
and leave the page pinned in memory. More precisely, the benevolent error
was that the truncation operation didn't add the reactivated page to any of
the paging queues, effectively pinning the page. This page would remain
pinned until the file was destroyed or the page was read or written. With
this change, the page is now added to the inactive queue.

in the ARP datagram generated by arprequest(). If caller doesn't
supply the address, then it is either picked from CARP or hardware
address of the interface is taken.
While here, make several minor fixes:
- Hold IF_ADDR_RLOCK(ifp) while traversing address list.
- Remove not true comment.
- Access internet address and mask via in_ifaddr fields,
rather than ifaddr.
If set to 1, no ABORT is sent back in response to an incoming
INIT. If set to 2, no ABORT is sent back in response to
an out of the blue packet. If set to 0 (the default), ABORTs

- Use Elf32_Addr as default, the only field that is
64 bitw wide is R_MIPS_64
- Add R_MIPS_HIGHER and R_MIPS_HGHEST handlers
- Handle R_MIPS_HI16 and R_MIPS_LO16 for both .rel and
.rela sections
The effect of this was, for clients mounted via inet6 addresses,
that the DRC cache would never have a hit in the server. It also
broke NFSv4 callbacks when an inet6 address was the only one available
in the client. This patch fixes the above, plus deletes opt_inet6.h
from a couple of files it is not needed for.

Since UFS_ACL is enabled by default for GENERIC kernels, this shouldn't
break anything - but please beat me to fix things if it does.
This reduces the footprint of the kernel on small embedded systems
(think <1MB flash for the compressed kernel image) just enough to
actually fit.
From the NetBSD bug:
The way how hexdump(1) parses escape sequences has some bugs.
It shows up when an escape sequence is used as the non-last character

where they've disabled all the wireless devices/framework.
This is just a build workaround. If you're actively using wireless,
you must still define AH_SUPPORT_AR5416 as I'm not sure what else
will break!
The real solution is to make the module build depend if AH_SUPPORT_AR5416
is defined, as well as make the 11n code in if_ath_tx.c and if_ath_tx_ht.c
completely optional (maybe depend upon ATH_SUPPORT_11N.)

Allow setting big MTU values on the pfsync interface but not larger
than the syncdev MTU. Prompted by the discussion with and tested
by Maxim Bourmistrov; ok dlg, mpf
Consistently use sc_ifp->if_mtu in the MTU check throughout the
module. This backs out r228813.
This was preventing the ath driver from being loaded at runtime.
It worked fine when compiled statically into the kernel but not when
kldload'ed after the system booted.
The root cause was that PCIR_INTLINE (register 60) was being
overwritten by zeros when register 62 was being written to.
A subsequent read of this register would return 0, and thus
the rest of the PCI glue assumed an IRQ resource had already
been allocated. This caused the device to fail to attach at
runtime as the device itself didn't contain any IRQ resources.
TODO: go back over the ar71xx and ar724x PCI config read/write
code and ensure it's correct.
