not have VTOC information about the partitions, it will be created.
This is because the VTOC information is used for the partition type
and FreeBSD's sunlabel(8) does not create nor use VTOC information.
For this purpose, new tags have been added to support FreeBSD's
partition types.
structure. This allows per-CPU variations of struct pmap on a
single architecture without affecting the machine-independent
fields. As such, the PMAP variations don't affect the ABI. They
become part of it.
CPUFREQ_DRV_SETTINGS(). The value of count on input is used to
prefent overflow of the settings buffer passed into CPUFREQ_DRV_SETTINGS().
This corrects the "est: CPU supports Enhanced Speedstep, but is not recognized."

than rely on the lockmgr support [1]:
* bump the waiters only if the interlock is held
* let brelvp() return the waiters count
* rely on brelvp() instead than BUF_LOCKWAITERS() in order to check
for the waiters number
- Remove a namespace pollution introduced recently with lockmgr.h
including lock.h by including lock.h directly in the consumers and
making it mandatory for using lockmgr.
- Modify flags accepted by lockinit():
* introduce LK_NOPROFILE which disables lock profiling for the
specified lockmgr
* introduce LK_QUIET which disables ktr tracing for the specified
lockmgr [2]
* disallow LK_SLEEPFAIL and LK_NOWAIT to be passed there so that it
can only be used on a per-instance basis
- Remove BUF_LOCKWAITERS() and lockwaiters() as they are no longer
used
This patch breaks KPI so __FreBSD_version will be bumped and manpages
updated by further commits. Additively, 'struct buf' changes results in
a disturbed ABI also.
[2] Really, currently there is no ktr tracing in the lockmgr, but it
will be added soon.

Use the correct value of errno. Although the errno value passed into
printf() follows the *env() call, it is not guaranteed to be the errno
from that call. When I wrote the regression tester, the environment I
used did pass the errno from the call. Consolidate the print for the
return code and errno into a function in the process of fixing this.

partition table is empty, check to see if we have something that
looks sufficiently like a BPB. On non-i386 machines, the boot
sector typically doesn't contain boot code; the end of the boot
sector is all zeroes. This is also where the partition table is
for MBRs.
We only check the sector size and cluster size, as that seems to
be the most reliable across implementations, BPB versions and
platforms.
just em, there is an igb driver (this follows behavior with our Linux drivers).
All adapters up to the 82575 are supported in em, and new client/desktop support
will continue to be in that adapter.
The igb driver is for new server NICs like the 82575 and its followons.
Advanced features for virtualization and performance will be in this driver.
Also, both drivers now have shared code that is up to the latest we have
released. Some stylistic changes as well.
Enjoy :)
code to add padlock features to the CPU model on VIA CPUs was no longer
effective. Change the code to instead output a separate printf during
dmesg for VIA Padlock features similar to other cpuid feature bitmasks.

Note: it may be a good idea to deduce obsolete usr/lib32/ files from
obsolete lib/ and usr/lib/ files.

(reported by joe@). Also fix a benign uninitialized variable bug.
Update and tidy the copyright.
Add "show sysregs" command to ddb. On i386, this gives gdt, idt, ldt,
cr0-4, etc. Support should be added for other platforms that have a
different set of registers for system use.
while still restricting auto-channel select to only those channels
permitted by regulatory constraints (sorta, we're still missing the
checks to honor radar and noadhoc status on channels). This somehow
got lost in the initial merge of the revised scanning code.
