becomes a size issue later, krw has a tiny crc32 to use instead.

Eliminate kernel option GPT and associated #ifdef GPT/#endif. Let
everybody get on the GPT bandwagon and we'll see what wheels fly
off.

Code abusing the radix internals for the routing table should now
includes <net/rtable.h> and only deal with "struct rtentry".
Code using a radix tree for another purpose can still include
<net/radix.h>.

"shared reference pointers".
srp allows concurrent access to a data structure by multiple cpus
while avoiding interlocking cpu opcodes. it manages its own reference
counts and the garbage collection of those data structure to avoid
use after frees.
internally srp is a twisted version of hazard pointers, which are
a relative of RCU.
jmatthew wrote the bulk of a hazard pointer implementation and
changed bpf to use it to allow mpsafe access to bpfilters. however,
at s2k15 we were trying to apply it to other data structures but
the memory overhead of every hazard pointer would have blown out
significantly in several uses cases. a bulk of our time at s2k15
was spent reworking hazard pointers into srp.
this diff adds the srp api and adds the necessary metadata to struct
cpuinfo on our MP architectures. srp on uniprocessor platforms has
alternate code that is optimised because it knows there'll be no
concurrent access to data by multiple cpus.
srp is made available to the system via param.h, so it should be
available everywhere in the kernel.
the docs likely need improvement cos im too close to the implementation.

user-mode. Yet, no need for every single driver to fiddle with the
conversion code as they are done transparently by common MI code. With

but move the rest of the Linux-specific ioctl() handling into linux_socket.c
This lets struct osockaddr finally move from sys/socket.h to protocols/talkd.h

This allows ddb's "trace" command to include file and line numbers:
ddb{0}> trace
Debugger() at Debugger+0x9 [../../../../arch/amd64/amd64/db_interface.c:405]
ddb_sysctl() at ddb_sysctl+0x1b4 [../../../../ddb/db_usrreq.c:104]
sys___sysctl() at sys___sysctl+0x216 [../../../../kern/kern_sysctl.c:229]
syscall() at syscall+0x297 [../../../../sys/syscall_mi.h:84]
--- syscall (number 202) ---
end of kernel
end trace frame: 0x7f7ffffcf1d7, count: -4
acpi_pdirpa+0x4117aa:
For this to work, it requires using a new version of boot(8), and
booting a kernel with the .debug_line section present (e.g., building
with ``makeoptions DEBUG="-g"'' and then booting the bsd.gdb kernel
instead of the stripped bsd kernel).
Still a WIP, but no failure reports yet. Committing so further
development and testing can happen in tree.

The interface has been disabled by default for about 4 years and
currently there's not much value in having it around at all.

bluetooth support doesn't work and isn't going anywhere. the current
design is a dead end, and should not be the basis for any future support.
general consensus says to whack it so as to not mislead the unwary.

ALTQ has served us well for years and was extremely important not just for
us, but for the entire bandwidth management arena. Back when we got altq,
the subject was not yet well researched and understood, which is why altq
is the framework with pluggable schedulers it is. Kenjiro Cho (kjc@) did an
amazing job there.
Now, more than 10 years later, we do have a good understanding and can use
a simpler framework with just one priority queueing and one bandwidth
shaping mechanism each - the new queueing subsystem. Last not least because
it is incredibly painful to maintain both in parallel, it is time for altq
to depart. Farewell, thanks for many years of good service. Everybody
using any form of "not just fifo" queueing owes Kenjiro a lot. At least
buy him a beer when you meet him.
And, allow me this personal note, thanks Kenjiro, working with you on the
topic has always been a great pleasure and I learned a lot from you. Thanks!
