page table pages have to be preallocated ...'', violates an assumption made
by minidumpsys(): kernel_vm_end is the highest virtual address that has ever
been used by the kernel. Now, however, the kernel code, data, and bss may
reside at addresses beyond kernel_vm_end. This revision modifies the upper
bound on minidumpsys()'s two page table traversals to account for this
possibility.
The changes to make the option work are already in place, but I missed
the patch hunk that adds it to the getopt() option-handling loop.

to vm_page_alloc() instead of VM_ALLOC_SYSTEM. VM_ALLOC_SYSTEM was the
logical choice before FreeBSD 7.0 because VM_ALLOC_INTERRUPT could not
reclaim a cached page. Simply put, there was no ordering between
VM_ALLOC_INTERRUPT and VM_ALLOC_SYSTEM as to which "dug deeper" into the
cache and free queues. Now, there is; VM_ALLOC_INTERRUPT dominates
VM_ALLOC_SYSTEM.
While I'm here, teach pmap_growkernel() to request a prezeroed page.

mininal set of ports required to make the docs. However,
we also need ports/sysutils/cdrtools in order to make the
ISO images. When a platform doesn't have packages, the
release will fail in that case. Add ports/sysutils/cdrtools
to RELEASEPORTSMODULE for the DOMINIMALDOCPORTS case to
handle the NOPORTS release build.
Note that this change doesn't try to handle the NOPORTS with
NODOC case. For we have NOPORTSATALL set and it seems wrong
to check out a ports module in that case.
inpcb. When directly invoking udp_notify() from udp_ctlinput(), acquire
only a read lock; we may still see write locks in udp_notify() as the
in_pcbnotifyall() routine is shared with TCP and always uses a write lock
on the inpcb being notified.

some code paths, global or inpcb write locks are required, but for other
code paths, read locks or no locking at all are sufficient for the data
structures.

source or a specific destination address is requested as part of a send
on a UDP socket, read lock the inpcb rather than write lock it. This
will allow fully parallel transmit down to the IP layer when sending
simultaneously from multiple threads on a connected UDP socket.
Parallel transmit for more complex cases, such as when sendto(2) is
invoked with an address and there's already a local binding, will
follow.

the syscall code and acquires various event subsystem locks as needed.
The handling of the NOTE_TRACK for EVFILT_PROC is currently done by
calling the kqueue_register() from filt_proc() filter, causing recursive
entrance of the kqueue code. This results in the LORs and recursive
acquisition of the locks.
Implement the variant of the knote() function designed to only handle
the fork() event. It mostly copies the knote() body, but also handles
the NOTE_TRACK, removing the handling from the filt_proc(), where it
causes problems described above. The function is called from the fork1()
instead of knote().
When encountering NOTE_TRACK knote, it marks the knote as influx
and drops the knlist and kqueue lock. In this context call to
kqueue_register is safe from the problems.
An error from the kqueue_register() is reported to the observer as
NOTE_TRACKERR fflag.
