we don't have access to sysmon_envsys(8)'s copy at refresh time. (The
refresh is driven completely within the driver, and sysmon is uninvolved.)
Resolves unexpected alarms (as reported by David Young) such as over-limit
alarms on fan sensors which have only lower limit values.
taking a reference to curlwp's by calling fd_hold(). If lwp_create()
is called from fork1(), then l2 != curlwp, but l2's and not curlwp's
filedesc_t whose reference we should take.
This change stops the problem I describe in
<http://mail-index.netbsd.org/tech-kern/2009/07/09/msg005422.html>,
where /dev/rsd0a is never properly closed after fsck / runs on it.
This change seems to quiet my USB backup drive, sd0 at scsibus0 at
umass0, which had stopped spinning down when it was not in use:
The unit probably stayed open after mount(8) tried (and failed:
errant fstab entry) to mount it.
I am confident that this change is an improvement, but I doubt that
it is the last word on the matter. I hate to get under the filedesc_t
abstraction by fiddling with fd_refcnt, and there may be something
I have missed, so somebody with greater understanding of the file
descriptors code should have a look.

Admitedly these are not going to be noticed when ukbd(4) is around.
While here, correct a typo (that's also in the HUT document),
and normalize to ASCII a non-UTF-8 encoding of "moire".

%fs on i386, %gs on amd64 registers, before using them. Otherwise, it
might be invalid/garbage, eg. IPI can interrupt userspace.

Thanks <drochner> for reporting and testing of patch.
Changes from dhcpcd-5.0.5 include
* Fix crash on MIPS, fixes PR bin/41682
Thanks to Tim McIntosh <tmcintos@eskimo.com> for the patch
* Save and restore interface MTU when changing
* IP whitelist
* Ensure that the lease and pidfile directories exist at startup
would push out elements to fillup-read only when the time had come for them.
This could then trickle feed the read queue slowly, but fast enough to prevent
it from switching state.
must not allocate a pmf_event_workitem_t using kmem_alloc(9). Use
pool_cache(9), instead, because it is safe in interrupt context.
Thanks, rmind@, for catching the problem and suggesting the solution.
