o The function is defined unconditionally but depends on SPR_SVR,
which is defined conditionally.
o spr.h defines mfspr() and mtspr(), which is no worse to use.
while holding the socket buffer lock. These leads to an
immediate panic due to recursing the socket buffer lock. This
bug was introduced in uipc_syscalls.c:1.240, but masked by
another bug until that was fixed in uipc_syscalls.c:1.269.
Note that the current fix isn't perfect, but better than
panicking: normally we guarantee that simultaneous invocations
of a system call to write on a stream socket won't be
interlaced, which is ensured by use of the socket buffer sleep
lock. This is guaranteed for the sendfile headers, but not
trailers. In practice, this is likely not a problem, but
should be fixed.

People without network connectivity forget basics like this... This
is in keeping with historic UPDATING entries which try to provide
basic information in the entry, and a pointer to more extensive
information documenting the new thing.
Retire pmap_track_modified(). We no longer need it because we do not
create managed mappings within the clean submap. To prevent regressions,
add assertions blocking the creation of managed mappings within the clean
submap.

total of 6 interrupt resources for scc(4) on macio(4). This
is 3 per channel, of which the 1st of each channel is the
interrupt associated with the SCC. The other 2 are for DMA
operation.
Change scc_bfe_attach() to accept an argument that's the
number of interrupts per channel (ipc) and change each bus
front-end (bfe) to pass that argument through a wrapper
for the device_attach method.
For now, we only allocate the 1st interrupt of each channel
to perserve behaviour.
by the parent for interrupt resources. This corrects parsing of
the interrupts property.
With parsing of the property fixed, add all interrupts to the
resource list. Bump the max. number of interrupts from 5 to 6
as scc(4) attached to macio(4) has 6 interrupts (3 per channel).

unused on sparc64 since removing the last traces of sio(4) in
sparc64 configuration files in favor for uart(4) over three
years ago. If similar functionality is required again it should
be brought back as an MD intr_pending() which works for all
busses by using for example interrupt controller hooks.

* Get the kernel module file name rather than hard-coding it like on Solaris.
* Use FreeBSD's process library API.
* Handle FreeBSD's different lock types.
* Get the list of loaded providers via a syscall.
* There are a few placeholders in here for which there isn't libproc
support code yet. This is relevent to userland tracing. This set of
commits is designed to get kernel tracing up and running, with the
userland stuff to follow later.
error is returned all the way back to the dtrace app, it's hard to
figure out where that error came from.
Add a couple of functions to get and set the error location which can
be optionally compiled into the library.
