- Document different semantics for ACPI_WMI_PROVIDES_GUID_STRING_METHOD
acpi_wmi.c:
- Modify acpi_wmi_provides_guid_string_method to return absolut number of
instances known for the given GUID.
acpi_hp.c:
- sysctl dev.acpi_hp.0.verbose to toggle debug output
- A modification so this can deal with different array lengths
when reading the CMI BIOS - now it works ok on HP Compaq nx7300
as well.
- Change behaviour to query only max_instance-1 CMI BIOS instances,
because all HPs seen so far are broken in that respect
(or there is a fundamental misunderstanding on my side, possible
as well). This way a disturbing ACPI Error Field exceeds Buffer
message is avoided.
- New bit to set on dev.acpi_hp.0.cmi_detail (0x8) to
also query the highest guid instance of CMI bios
acpi_hp.4:
- Document dev.acpi_hp.0.verbose sysctl in man page
- Document new bit for dev.acpi_hp.0.cmi_detail
- Add a section to manpage about hardware that has been reported
to work ok

The IOCTL functionality is entirely duplicated and routing sockets

used kernel TLB slots when unloading the kernel or modules, which
results in havoc when loading a kernel and modules which take up
less TLB slots afterwards as the unused but locked ones aren't
accounted for in virtual_avail. Eventually this should be fixed
in the loader which isn't straight forward though and the kernel
should be robust against this anyway. [1]
- Ensure that the addresses allocated directly from phys_avail[] by
pmap_bootstrap_alloc() are always colored properly. This implicit
assumption was broken in r194784 as unlike the other consumers the

inbound data waiting on a filedescriptor, such as a pipe or a socket,
for instance by using select(2), poll(2), kqueue(2), ioctl(FIONREAD)
etc.
But we have no way of finding out if written data have yet to be
disposed of, for instance, transmitted (and ack'ed!) to some remote
host, or read by the applicantion at the far end of the pipe.
The closest we get, is calling shutdown(2) on a TCP socket in
non-blocking mode, but this has the undesirable sideeffect of
preventing future communication.
Add a complement to FIONREAD, called FIONWRITE, which returns the
number of bytes not yet properly disposed of. Implement it for
all sockets.
Background:
A HTTP server will want to time out connections, if no new request
arrives within a certain period after the last transmitted response
has actually been sent (and ack'ed).
For a busy HTTP server, this timeout can be subsecond duration.
In order to signal to a load-balancer that the connection is truly
dead, TCP_RST will be the preferred method, as this avoids the need
for a RTT delay for FIN handshaking, with a client which, surprisingly
often, no longer at the remote IP number.
If a slow, distant client is being served a response which is big
enough to fill the window, but small enough to fit in the socket
buffer, the write(2) call will return immediately.
If the session timeout is armed at that time, all bytes in the
response may not have been transmitted by the time it fires.
FIONWRITE allows the timeout to check that no data is outstanding
on the connection, before it TCP_RST's it.
