o Provide separate functions for SIOCAIFADDR and for SIOCDIFADDR, with
clear code flow from beginning to the end. After that the rest of
in_control() gets very small and clear.
o Provide sx(9) lock to protect against parallel ioctl() invocations.
o Reimplement logic from r201282, that tried to keep localhost route in
table when multiple P2P interfaces with same local address are created
and deleted.

net.link.ether, originally it had been at another wrong namespace. It was
incorrectly documented at incorrect manual page arp(8). Since new-ARP commit,
the tunable have been consulted only on route addition, and ignored on route
deletion. Behaviour of a system with tunable turned off is not fully correct,
and has no advantages comparing to normal behavior.

coalesce would extend the object to keep pages for the anonymous
mapping created by the process. The pages has no relations to the
tmpfs file content which could be written into the corresponding
range, causing anonymous mapping and file content aliasing and
subsequent corruption.
Another lesser problem created by coalescing is over-accounting on the
tmpfs node destruction, since the object size is substracted from the
total count of the pages owned by the tmpfs mount.

emulation of the call instruction caused by reversing the uaddr and kaddr
arguments when copying data out to userland: the suword* functions take the
uaddr as the first argument whereas copyout(9) takes the kaddr as the first
argument. This also partially undoes the fixes from r257143.

allocates kva space from the top down for the device mappings and builds
entries in an internal table which is automatically used later by
arm_devmap_bootstrap(). The platform code just calls the new
arm_devmap_add_entry() function as many times as it needs to (up to 32
entries allowed; most platforms use 2 or 3 at most).
There is also a new arm_devmap_lastaddr() function that returns the lowest
kva address allocated; this can be used to implement initarm_lastaddr()
which is used to initialize vm_max_kernel_address.
The new code is based on a similar concept developed for the imx family
SoCs recently. They will soon be converted to use this new common code.

ptrace(2) to work.
libdtrace does not seem to stop target processes before trying to remove
their breakpoints, so we were previously failing to remove the breakpoint
on r_debug_state() in rtld. This was causing processes to die with SIGTRAP
if they called dlopen(3) after dtrace(1) had detached.

static device mappings, rather than as the first of the initializations
that a platform can hook into. This allows a platform to allocate KVA
from the top of the address space downwards for things like static device
mapping, and return the final "last usable address" result after that and
other early init work is done.
Because some platforms were doing work in initarm_lastaddr() that needs to
be done early, add a new initarm_early_init() routine and move the early
init code to that routine on those platforms.
Rename platform_devmap_init() to initarm_devmap_init() to match all the
other init routines called from initarm() that are designed to be
implemented by platform code.
Add a comment block that explains when these routines are called and the
type of work expected to be done in each of them.

inside vmm.ko is the local apic and it is always at a fixed guest physical

the prefix arm_devmap_ on the function and type names (already a few of
these things found their way into MI code, hopefully it will be harder to
do by accident in the future).

Instead, just use the bootstrap compiler's built-in default. This
should eventually make it possible to build stable/9 on head, or on
stable/10, which ship without libstdc++ by default.

out common code related to mapping device memory into a new devmap.c file.
Remove the growing duplication of code that used pmap_devmap_find_pa() and
then did some math with the returned results to generate a virtual address,
and likewise in reverse to get a physical address. Now there are a pair
of functions, arm_devmap_vtop() and arm_devmap_ptov(), to do that. The
bus_space_map() implementations are rewritten in terms of these.
This explanation is supposed to be simpler and better. In particular
