mutexes and replacing the obsolete if_watchdog interface. The ndis_ticktask
function calls into ieee80211_new_state under one condition with NDIS_LOCK
held. The ieee80211_new_state would call into ndis_start in some cases too,
resulting in the occasional case where ndis_start acquires NDIS_LOCK from
inside the NDIS_LOCK held by ndis_ticktask.

page directory pages from VM_MIN_KERNEL_ADDRESS through the end of the
kernel's bss. Specifically, the dependence was in pmap_growkernel()'s one-
time initialization of kernel_vm_end, not in its main body. (I could not,
however, resist the urge to optimize the main body.)
Reduce the number of preallocated page directory pages to just those needed
to support NKPT page table pages. (In fact, this allows me to revert a
couple of my earlier changes to create_pagetables().)
- Fix a number of potential memory leaks in libgeom related to doing realloc
without freeing old pointer if things go wrong.
- Fix a number of places in libgeom where malloc and calloc return values
were not checked.
- Check malloc return value and provide sufficient warning messages when XML
parsing fails.

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

source or a specific destination address is requested as part of a send

will allow fully parallel transmit down to the IP layer when sending

Parallel transmit for more complex cases, such as when sendto(2) is

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.
