an NVidia Tegra 2 CPU.
Tegra 2 needs an external patch to pmap for atomic operations to work. Even
with this the Kernel only gets to the mount root prompt. As such Tegra
support is considered experimental, however adding the kernel config will
help ensure the Tegra code builds.
indexing. When a device has gone it is not removed from device_map
table but just its entry_p field is set to NULL.
So when traversing device_map in disk_OS_get_ATA_disks() and
disk_OS_get_MD_disks() check for entry_p being NULL, otherwise the
bsnmpd crash is possible when a removed map entry is dereferenced.
Before the fix, for disk_OS_get_ATA_disks() the crash could be easily
reproduced running:
atacontrol detach ata1
The crash was not observed in disk_OS_get_MD_disks() because currently
snmp_hostres does no see md(4) disks: to get the device list it uses
devinfo(3), which does not return md devices.

- Remove cvs(1) references.
- Remove CVS* environment references.
- Add default entries for the default SVNROOT for the Ports
Collection, and Documentation Project.
- While here, update 'SGML-based documentation' to 'XML-based',
since the recent SGML->XML conversion.
- Update an example providing SVNROOT environment usage.

These are intended for software TX filtering support, where the NIC
decides there has been too many successive failues to a destination
and will filter it.
Although the filtering is done per-destination (via the keycache),
the state and queue is kept per-TID for now. It simplifies the overall
architecture design and locking.
Whilst here, add ATH_TID_UNLOCK_ASSERT().
* Don't treat high percentage failures as "sucessive failures" - high
MCS rates are very picky and will quite happily "fade" from low
to high failure % and back again within a few seconds. If they really
don't work, the aggregate will just plain fail.
* Only sample MCS rates +/- 3 from the current MCS. Sample will back off
quite quickly, so there's no need to sample _all_ MCS rates between
a high MCS rate and MCS0; there may be a lot of them.
* Modify the smoothing rate to be 75% rather than 95% - it's more adaptive
but it comes with a cost of being slightly less stable at times.
A per-node, hysterisis behaviour would be nicer.
such that when commenting/uncommentting lines, horizontal spacing is
maintained...
Also fix some minor comment formatting to line things up, etc...

This reduces code duplication and code size.
/usr/bin/printf is not affected.
Side effect: different error messages when certain builtins are passed
invalid options.
X86: Emitting x87 fsin/fcos for sinf/cosf is not safe without unsafe
fp math.
This should make clang emit calls to libm for sinf/cosf by default.

(download microcode with offsets, save, and activate).
SATI translation layer was incorrectly using allocation length instead
of blocks, and was constructing the ATA command incorrectly.
Also change #define to specify that the 512 block size here is
specific for DOWNLOAD_MICROCODE, and does not relate to the device's
logical block size.
