memory disk is larger than the number of available sf_bufs, this improves
performance on SMPs by eliminating interprocessor TLB shootdowns. For
example, with 6656 sf_bufs, the default on my test machine, and a 256MB
swap-backed memory disk, I see the command
"dd if=/dev/md0 of=/dev/null bs=64k" achieve ~489MB/sec with the default,
shared mappings, and ~587MB/sec with CPU private mappings.

base transfer speed to CAM. The actual value used (40MB/s) is fairly
arbitrary, but assumes the same 33% overhead as was implied by the
1MB/s figure we used for USB1 devices.

are not added to the list(s) of available settings. However, other drivers
can call the CPUFREQ_DRV_SETTINGS() method on those devices directly to
get info about available settings.
Update the acpi_perf(4) driver to use this flag in the presence of
"functional fixed hardware." Thus, future drivers like Powernow can
query acpi_perf for platform info but perform frequency transitions
themselves.

independent control will be supported but this is good enough for now.

former is callable from user space and the latter from the kernel one. Make
kernel version take additional argument which tells if the respective call
should check for additional restrictions for sending signals to suid/sugid
applications or not.
Make all emulation layers using non-checked version, since signal numbers in
emulation layers can have different meaning that in native mode and such
protection can cause misbehaviour.
As a result remove LIBTHR from the signals allowed to be delivered to a
suid/sugid application.

throttling, neglecting to do this kept the sysctls from appearing.
Attach an acpi_throttle device to each CPU that supports it.
Don't add a device if the P_BLK is invalid or if _PTC is not present.
This removes extraneous probe/attach failure messages on some machines.
Make the cpu throttle state local to the softc to account for partial
successes when changing the clock rate on MP machines.

When reading the bodies of Zip archive entries, request a minimum of 1
byte, rather than a minimum of the full entry size. This is faster
(since it does not force the decompression layer to combine reads) and
works around a bug in the "none" decompression handler (which I'm
testing a separate fix for now). I've also renamed "bytes_read" to
"bytes_avail" in several places to more accurately reflect that the
value returned from (a->compression_read_ahead) is the number of bytes
available, not necessarily the number of bytes requested.

(padding) entries, extract inode value from PX entry, recognize SP and
ST (start/end of SUSP extensions).
I don't enforce SP yet, as I've seen CDROMs which use Rockridge
extensions but don't have the SP record (which is officially
required).
The ISO9660 support is now mature enough to extract FreeBSD
distribution CDROMs created with mkisofs.

For example, when using 'gunzip | tar' to decompress.
Also, fix some style issues (write null character as '\0').

for nodes hanging off of Central (untested), FireHose (untested) and
PCI (tested) busses.
- Add an additional parameter to OF_decode_addr() which specifies the
index of the register bank to decode.
These should allow to eventually add support for the Z8530 hanging off of
FireHose to uart(4) and to write support for PCI-based graphics adapters.
