I used the following command to determine which source files were
unneeded:
| for i in `find lib/clang -name '*.o'`
| do
| MATCHES="`(nm -g --defined-only $i; nm -g --defined-only \
| usr.bin/clang/clang/clang) | sed -e 's/.* //' | \
| sort | uniq -d | wc -l`"
| [ $MATCHES -eq 0 ] && echo "$i: unneeded"
| done
This should slightly improve the build times.

Explicitely assert that the calling conventions for fpudrop() are
adhered too. In cpu_thread_exit(), add missed critical section entrance.

Features:
- configurable amount of days between scrubs (default value or per pool)
- do not scrub directly after pool creation (respects the configured
number of days between scrubs)
- do not scrub if a scrub is in progress
- tells how to see the status of the scrub
- tells how many days since the last scrub if it skips the scrubbing
- warns if a non-existent pool is specified explicitely
(default: no pools specified -> all currently imported pools are
handled)
- runs late in the periodic run to not slow down the other periodic daily
scripts

Although the sysctls are marked with CTLFLAG_RD and the values will stay
immutable, current sysctl implementation stores value pointer in
void* type, which means that const qualifier is discarded anyway
and some newer compilers complaint about that.
We can't use de-const trick in sysctl implementation, because in that
case we could miss an opposite situation where a const value is used
with CTLFLAG_RW sysctl.

* Fix a bug where a NULL pointer was dereferenced when interfaces
come and go at a high rate.
* Fix a bug where inps where not deregistered from iterators.
* Fix a race condition in freeing an association.
* Fix a refcount problem related to the iterator.
Each of the above bug results in a panic. It shows up when

we grow more descriptors, but I'll reconsider readding them once we get there.
Passing (a = b) expression to FD_ISSET() is bad idea, as FD_ISSET() evaluates
its argument twice.

and vm_pageout_page_stats(). These checks were recently introduced by
the first page locking commit, r207410, but they are not needed. At
the same time, eliminate some redundant accesses to the page's object
field. (These accesses should have neen eliminated by r207410.)
Make the assertion in vm_page_flag_set() stricter. Specifically, only
managed pages should have PG_WRITEABLE set.
Add a comment documenting an assertion to vm_page_flag_clear().
It has long been the case that fictitious pages have their wire count
permanently set to one. Add comments to vm_page_wire() and
vm_page_unwire() documenting this. Add assertions to these functions
as well.
Update the comment describing vm_page_unwire(). Much of the old
comment had little to do with vm_page_unwire(), but a lot to do with
_vm_page_deactivate(). Move relevant parts of the old comment to
_vm_page_deactivate().
Only pages that belong to an object can be paged out. Therefore, it
is pointless for vm_page_unwire() to acquire the page queues lock and
enqueue such pages in one of the paging queues. Generally speaking,
such pages are immediately freed after the call to vm_page_unwire().
Previously, it was the call to vm_page_free() that reacquired the page
queues lock and removed these pages from the paging queues. Now, we
will never acquire the page queues lock for this case. (It is also
worth noting that since both vm_page_unwire() and vm_page_free()
occurred with the page locked, the page daemon never saw the page with
its object field set to NULL.)
Change the panic with vm_page_unwire() to provide a more precise message.
