- Remove sme_mtx, a global lock (sme_list_mtx) is used to access to
the sysmon envsys device.
- Allocate memory with KM_NOSLEEP rather than KM_SLEEP if there's a
mutex held, to avoid sleeping.
- Remove sysmon_envsys_createplist() and add the logic into
sysmon_envsys_register().
- sysmon_envsys_register: allocate the array and dictionaries required
in advance for a device before the locking and adding the objects
into the array happens.
- Rename sme_make_dictionary() to sme_add_sensor_dictionary() and pass
to it the dictionary on which the objects will be stored for a sensor.
- Improve locking here and there.

by using a dynamic stack as well. Reorder arguments for the internalizer
as the iteration is always present and should go before possibly
NULL arguments.

there, although it needed a bug fix. Will look at adding arbitrary
directories next.
acquisition and final release out into gre_thread(). This will
fix a locking bug that LOCKDEBUG exposed: holding a spinlock over
an sosend() call is a no-no.
Cosmetic: join some lines, remove some unnecessary curly braces.
and dom_sa_len members from struct domain. Pools of fixed-size
objects are too rigid for sockaddr_dls, whose size can vary over
a wide range.
Return sockaddr_dl to its "historical" size. Now that I'm using
malloc(9) instead of pool(9) to allocate sockaddr_dl, I can create
a sockaddr_dl of any size in the kernel, so expanding sockaddr_dl
is useless.
Avoid using sizeof(struct sockaddr_dl) in the kernel.
Introduce sockaddr_dl_alloc() for allocating & initializing an
arbitrary sockaddr_dl on the heap.
Add an argument, the sockaddr length, to sockaddr_alloc(),
sockaddr_copy(), and sockaddr_dl_setaddr().
Constify: LLADDR() -> CLLADDR().
Where the kernel overwrites LLADDR(), use sockaddr_dl_setaddr(),
instead. Used properly, sockaddr_dl_setaddr() will not overrun
the end of the sockaddr.
interrupt stuff. This is mostly comprised of changes to the pmap modules to
work on multiprocessor systems without kernel_lock, and changes to speed up
tlb shootdowns.
pages immediately above and below the x86 interrupt stack so that
both an overgrown interrupt stack and other faults produce a page
fault trap. Condition this on the historical option NOREDZONE,
for now.
A comment said that they weren't in a struct for speed reasons but...
this should not affect performance because these variables are mostly
used to set other variables (hence they are read few times).

myself, some more money for my dealer of anxiolytics after reading
ip_output()'s twisted code maze.
