from our install description, pass the partition type (not only the file
system type). Sometimes (e.g. EFI boot partition on GPT) the filesystem
type (MSDOS) is not a unique selector.
the main effect of this is to make GCC and other libiberty using
tools use /tmp instead of /var/tmp for compiler temp files,
which can be a bottleneck on larger systems.
a survey of other platforms shows only OSX also uses /var/tmp,
everyone else has switched to /tmp long ago.
cons: some smaller systems may have a smaller /tmp than /var/tmp,
and this may cause builds to fail with out of space earlier.
point the build to /var/tmp using TMPDIR in this case.
one can argue that setting TMPDIR would work around this, but we
want to have the effect for all users without having special setup.
lock for use of the pagedaemon policy code. Discussed on tech-kern.

Having assertions here causes panic if target is missing anything
as shown in "dm: Add dummy target ->sync()/->secsize() to prevent panic on modload(8)".
Instead just return EINVAL if a handler(s) isn't implemented.

- Add code for 1000BASE-T SFP. It uses SGMII.
- Add extra delay in wm_serdes_power_up_link_82575(). Same as other OSes.
TODO:
- Module insertion/removal support. Currently, SFP detection is only done
in the driver's attach phase.
when the link is up, so it's not good to check in the attach function.
- There is an environment that both copper and fiber bits are set in EXTSR
but it support copper only. To resolve this problem, check the ESSR
register's HWCFG_MODE bit and drop unsupported bits.
- If the chip is in Fiber/Copper auto select mode, check which media is
selected. Currently, the code supports 88E1011, 88E1111 and 88E1112 only.
To support other chips documents are required.
module hook, we can share a common set of synchronization structures.
This cuts the amount of cacheline_aligned data for these structures by
50%.
Note that we still have a per-hook localcount, since we need to count
individual references.

Welcome to 9.99.22 !
return NULL, so check for this.
I got NULL pointer dereference here with a device showing:
[ 303.732632] ugen0: autoconfiguration error: setting configuration index 0 failed
in this commit. SFP module removal interrupt detects but not used yet:
- Detect SFP's 1000BASE-SX, 1000BASE-LX, 100BASE-FX and 1000BASE-T correctly.
- Detect the Media Auto Sense feature. Not supported yet.
- Add comment.
Link status event that is used to update link status sometimes
is not notified when link down. So, use Get Link Status response
that has the same information with the event.
The handling of the event is needed to detect link state
up because the response sometimes does not notify link up.
