that the usual macro for "ret" hides the detail of calling .mexitcount
before returning.
Fixed missing call to .mexitcount in lgdt(). This was missing on
i386's, mainly because lgdt() uses lret[q] insted of ret. This is
very unimportant since lgdt() is not (normally?) called until after
profiling is initialized.
in all USB ethernet drivers. The qdat structure contains a pointer
to the interface's struct ifnet and is used to process incoming
packets, so simultaneous use of two similar devices caused crashes
and confusion.
The if_udav driver appeared in the tree since Daan's PR, so I made
similar changes to that driver too.

stored in EEPROM or NVRAM. It's inspired by the NetBSD eeprom(8) and
the SunOS/Solaris eeprom(1M) utilities. Currently, this eeprom(8)
only supports systems equipped with Open Firmware and is only tested
on Sun machines but should work on any platform using Open Firmware.
A bit more specific, eeprom(8) can be used on these systems to do the
same under FreeBSD as can be done using the printenv and setenv
commandos in the boot monitor. One thing that only hardly can be done
using the boot monitor but easily with eeprom(8) is to write a logo
to the "oem-logo" property. eeprom(8) may also be useful to recover
the boot monitor password (in the default configuration only as root,
of course), i.e. when the boot monitor allows you to boot but you
can't alter the configuration because the password is unknown. The
man page may also be a useful reference of the various configuration
variables.
The idea of eeprom(8) is that handlers can be written to add support
for any firmware that stores such configuration in EEPROM or NVRAM;
sort of e.g. eeprom(1M) on Solaris/x86 is used to turn PAE-support
on and off (stored in a file then, not hardware). In FreeBSD, a
candidate for this would be a handler for the EFI boot environment
for FreeBSD/ia64.
eeprom(8) uses some code from NetBSD (eeprom.c and the base for
eeprom.8), the handler for the Open Firmware /options node
(ofw_options.[c,h]) was written using ofw_util.[c,h] from ofwdump(8).

- Make the code use the new OFIOCMAXVALUE instead of defining the maximum
length of property values locally.
- Move the application specific parts from ofw_util.c to ofwdump.c in
order to make ofw_util.c more library-like. While ofw_dump_properties()
could be made non-specific to ofwdump(8) it's currently optimized for
use in ofwdump(8) and making it a library-like function would just
complicate the code unnecessarily.
- Minor clean-up in ofw_util.c, e.g. make its use of getopt(3) the way
it's described in style(9), make its usage() static, etc.
- Add a comment in ofw_util.c about why it doesn't call usage() when
neither the "-a" option nor a node-name where given.
- Add ofw_optnode() and ofw_setprop(), helper functions for the
OFIOCGETOPTNODE and OFIOCSET ioctls respectively, to ofw_util.[c,h].
- Be consistent with the use of 'const' in ofw_util.[c,h] and add 'const'
to the function arguments that are acutally const but weren't declared
as such.
- Mark WARNS=6 clean.

identifiers, to openfirmio.h as OFIOCMAXNAME, so programs can use it
for buffer sizes etc.
Note: Although this is only a rough upper limit to make the code more
robust and to prevent the allocation of ridiculous amounts of memory,
the current limit of one page (8191 + '\0' in openfirm_getstr()) still
appears a bit high. The maximum length of OFW property names is 31.
I didn't find a maximum length for the device identifiers in the OFW
documentation but it certainly is much smaller than 8191, too.
- Enable the OFIOCSET ioctl, i.e. move it out from under #if 0.
- Don't use openfirm_getstr() for the property value in OFIOCSET, there
are also properties whose values aren't strings and it makes sense to
use a different maximum length for property values than OFW_NAME_MAX/
OFIOCMAXNAME. The maximum accepted property value is defined in
openfirmio.h as OFIOCMAXVALUE (currently the maximum size of the value
of the nvramrc property).
- Make OFIOCSET not return EINVAL when OF_setprop() returns a different
length for the written value than it was told to write, this is normal
for the text string values of the properties in the OFW /options node.
Instead, only return EINVAL if OF_setprop() returned -1 (value could
not be written or property could not be created). Add a comment about
the specialty of the OFW /options node.
- Make OFIOCSET return the length of the written value returned by
OF_setprop(), just like OF_getprop() does. Quite useful, at least for
debugging.

enough to contain the multibyte character, character does not straddle
buffer boundary) this results in only one call to mbrtowc() for each
wide character read.

This is only a performance improvement for now, but it would also be

to get a better sense of latency between events, such as time to
schedule an interrupt thread from time the interrupt occurred. Assert

being that PHYS_TO_VM_PAGE() returns the wrong vm_page for fictitious
pages but unwiring uses PHYS_TO_VM_PAGE(). The resulting panic
reported an unexpected wired count. Rather than attempting to fix
PHYS_TO_VM_PAGE(), this fix takes advantage of the properties of
fictitious pages. Specifically, fictitious pages will never be
completely unwired. Therefore, we can keep a fictitious page's wired
count forever set to one and thereby avoid the use of
PHYS_TO_VM_PAGE() when we know that we're working with a fictitious
page, just not which one.
