are now compiled in by default.
Note that MSR support in Xen depends on its version. rdmsr() should always
succeed, but wrmsr() to certain registers can end in a NOOP. In that case,
the error will be logged (see xm dmesg).
Setting CPU frequency (SpeedStep) requires Xen 3.3 with the option
cpufreq="dom0-kernel" passed down to hypervisor during boot.
Compiled and tested for SpeedStep under i386 for XEN3_DOM0 and XEN3PAE_DOM0
by jym@. amd64 was tested by Joel Carnat.

support -ve lengths (lock area before current offset).
Nothing in libc or the kernel allowed for this, so some random part
of the file would get locked (no idea which bits).
Although this could probably be fixed in libc, the stubs for posix file
locks for emulations could easily get into the kernel with -ve lengths.
So fixing in the kernel avoids those problems.
This also fixes PR/41620 (attempting to lock negative offsets) - which
is what I was looking into!
It seems that some revisions of the controllers hang while accessing
the VPD. Because VPD access routine is now unused, nuke it.
- Let TWSI reload EEPROM if VPD capability is detected. Reloading
the EEPROM will also set the Ethernet address, so age(4) now reads
AGE_PAR0 and AGE_PAR1 register to get the Ethernet address. This removes
removes a lot of hacks and enhance readability a lot.
- Double PHY reset timeout as it takes more time to take the PHY out of
power-saving state.
- Explicitly check power-saving state by checking undocumented PHY
registers. If link is not up, poke undocumented registers to take
PHY out of power-saving state. This is the same thing done by the
Linux driver.
- Don't rely on auto-clearing feature of master reset bit, just wait
1ms and check idle status of MAC.

and options. Don't allow the previously undocumented method to change the
maximum number of scores kept per user to be used on the system-wide high
score file. Sort options list in the man page. Bump its date.
Instead of doing actual page remapping, which we can't portably
do in userspace without extensive trickery (read: signals), simply
allocate the kva window with new physical backing, copy page
contents, return, and copy contents back in mapout. Since the
pages are locked during the mapping cycle, we can do this without
hazard.
* add lots of stubbies necessary for new stuff coming soon
restore the system from sleep. set/clear wake GPEs as specified before
entering sleep.
by default, the following devices are enabled for wake:
- sleep/power buttons
- lid switch
- pc kbd controller
