threads from invalid ones. The pthread structure is opaque to the user
so this change does not cause any incompatibilities.
Hopefully this change will help code that was written for draft 4
fail gracefully if the programmer ignores the compiler warning about
the change in the level of indirection for the argument passed to
pthread_detach(). I got burnt, so I fixed then (expletive deleted)
thing.
These functions comply with the revised standard. That should shut
Terry up!
Add a note about not touching errno and warn about previous drafts
of the standard which changed the level of indirection to the thread
argument. POSIX had a bit of trouble deciding what to do. So anyone
coding to both draft 4 and draft 10 (the final draft) will get burnt
by this function. I did. Grrr.
Explanation of the bug: when processing its first request, rarpd
opens a routing socket to send requests to the arp table. It keeps
that socket open afterwards, while waiting for new RARP requests.
Meanwhile, the data received on the routing socket fill up until
they are about 8Kbytes in size. Any additional data is lost.
When rarpd receives its next RARP request, it tries to access the
ARP table via a routing socket call, then waits for the answer to
its own request. This answer is lost because the received data is
already filled: when looking for the reply, rarpd receives only
8kbytes worth of data, then loops waiting forever.
Someone please test it on -STABLE and commit it. We can close the PR
when testing on STABLE is done.

- Attempt to handle PCI devices where the interrupt is
an ISA/EISA interrupt according to the mp table.
- Attempt to handle multiple IO APIC pins connected to
the same PCI or ISA/EISA interrupt source. Print a
warning if this happens, since performance is suboptimal.
This workaround is only used for PCI devices.
With these two workarounds, the -SMP kernel is capable of running on
my Asus P/I-P65UP5 motherboard when version 1.4 of the MP table is disabled.
Defer the WRITE SESSION command until the first write command, so that
it works like the prepare track command, allowing the device to be
closed after the command.
"time" wasn't a atomic variable, so splfoo() protection were needed
around any access to it, unless you just wanted the seconds part.
Most uses of time.tv_sec now uses the new variable time_second instead.
gettime() changed to getmicrotime(0.
Remove a couple of unneeded splfoo() protections, the new getmicrotime()
is atomic, (until Bruce sets a breakpoint in it).
A couple of places needed random data, so use read_random() instead
of mucking about with time which isn't random.
Add a new nfs_curusec() function.
Mark a couple of bogosities involving the now disappeard time variable.
Update ffs_update() to avoid the weird "== &time" checks, by fixing the
one remaining call that passwd &time as args.
Change profiling in ncr.c to use ticks instead of time. Resolution is
the same.
Add new function "tvtohz()" to avoid the bogus "splfoo(), add time, call
hzto() which subtracts time" sequences.

be worth much effort. Install all i386 binutils programs in
"/usr/libexec/elf". Disable a.out support in libbfd. It's too
dangerous to leave it in. Some of the utilities think they can
handle a.out, but they generate bad object files.
