- Add loader(8) variables for RB_DFLTROOT, RB_MUTE, and RB_PAUSE:
"boot_dfltroot", "boot_mute", and "boot_pause" respectively.
- Cause all flags passed by boot2 to set the respective loader(8)
boot_* variable. The end effect is that all flags from boot2
are now passed to the kernel.

The uma_zone data structure defines the size of its uz_cpu[] array as 1,
but then sizes the containing data structure at run-time to make room
for per-cpu cache data. Modify libmemstat to separately allocate a
buffer to hold per-cpu cache data, sized based on the run-time mp_maxid
variable when using libkvm to access UMA data. This avoids reading
invalid cache data from beyond the end of the uma_zone data structure
on the stack, which can result in invalid statistics and/or reads from
invalid kernel addresses.

When reporting an error reading from UMA per-cpu cache pointers using KVM,
return a KVM error rather than an out of memory error, so that the caller
reports the KVM error state. This replaces a misleading error message
with a more accurate although equally confusing one.

Read all_cpus variable out of kmem, and validate CPUs against the all_cpus
cpu mask before looking at the cache entries for the CPU. For systems
with sparse CPU id arrays, this skips otherwise uninitialized cache
structures.

present in kdump.1:1.15:
Add a "-H" argument to kdump, which causes kdump to print an additional
field holding the threadid. This is more useful for libthr than
libpthread, but still quite useful in libpthread as it can be used to
process interlaced records from multiple threads over the course of a
system call.
Detect old ktr_buffer values using the heuristic "if it's negative,
then it must not be a valid threadid". This may leave something to be
desired.

Reuse ktr_unused field in ktr_header structure as ktr_tid; populate

reasons, and cannot be changed to lwpid_t at this point.

Modify the IP fragment reassembly code so that it uses a new UMA zone,
ipq_zone, to allocate fragment headers from, rather than using cast mbuf
storage. This was one of the few remaining uses of mbuf storage for
local data structures that relied on dtom(). Implement the resource
limit on ipq's using UMA zone limits, but preserve current sysctl
semantics using a sysctl proc.

- Don't shift the clock frequency in MHz left by 8 before assigning it
to sbus_mdvec.dv_clock as sbus_mdvec.dv_clock is meant to be specified
in MHz. While this was a bug it shouldn't have affected FreeBSD/sparc64
as sbus_mdvec.dv_clock is used to limit the clock rate of chips when
a machine isn't able to support them at maximum speed which isn't the
case for sun4u machines.
- Remove the code that checks whether the clock frequency returned by
sbus_get_clockfreq() is 0 and falls back to 25MHz if it is as that's
already done in sbus(4).

Avoid creating (and subsequently using) fake opt_*.h files
when the modules are built with the kernel and hence actual
opt_*.h files are available in ${KERNBUILDDIR}. Fix a few
small bugs that would prevent this from working.
At last the build options of the modules become consistent
with those of the kernel unless the MODULES_WITH_WORLD way
still is used.

Do address assignment/removal operations after callbacks. Presently,
ifconfig callbacks are used for L2 configuration, media and vlan,
so actions associated with address assignment, like sending out a
gratuitous ARP, should go when L2 is running already.
Return ifvlan.c to the state of rev. 1.7.2.2 -- undo the last
back-out. The above change to ifconfig.c lets us use a callback
for vlan set-up without facing the evil side-effects from IP
assignment to an orphaned vlan interface.
