37e21e18ac Assert at compile time that structures which need to be a power of 
2 really are.
Move a trace to before flushw in case it goes off the deep end.

274ee4b819 Be paranoid about the sizeof passed to db_get_value, not all trapframe 
fields are u_long.

f5832be731 Implement dcache_inval_phys, which shoots the cache lines that correspond 
to a specific physical address.  This is used for page copy and zero
routines which use physical addresses directly.

21d56e9c33 Make AIO a loadable module. 
Remove the explicit call to aio_proc_rundown() from exit1(), instead AIO
will use at_exit(9).

Add functions at_exec(9), rm_at_exec(9) which function nearly the
same as at_exec(9) and rm_at_exec(9), these functions are called
on behalf of modules at the time of execve(2) after the image
activator has run.

Use a modified version of tegge's suggestion via at_exec(9) to close
an exploitable race in AIO.

Fix SYSCALL_MODULE_HELPER such that it's archetecuterally neutral,
the problem was that one had to pass it a paramater indicating the
number of arguments which were actually the number of "int".  Fix
it by using an inline version of the AS macro against the syscall
arguments.  (AS should be available globally but we'll get to that
later.)

Add a primative system for dynamically adding kqueue ops, it's really
not as sophisticated as it should be, but I'll discuss with jlemon when
he's around.

529110b963 Rename and renumber trap types to comply with the user trap types as 
specified by the sparc abi.  We use numerically higher values for all
internal kernel types.
Remove soft trap types which need to be exposed to userland.  They will
move to utrap.h.

4339fe0983 1. Certain tlb operations need to be atomic, so disable interrupts for 
their duration.  This is still only effective as long as they are
   only used in the static kernel.  Code in modules may cause instruction
   faults which makes these break in different ways anyway.
2. Add a load bearing membar #Sync.
3. Add an inline for demapping an entire context.

47d6b4a644 Fix my breakage to the low-level hardware sync drivers brought by the 
inclusion of VJ compression into sppp.

Now, instead of the need to include this and that and everything plus
the kitchensink in each of those drivers, struct sppp uses struct
slcompress as an opaque structure only referenced by a pointer.  The
actual structure is then malloced at initialization time.

While i was at it, also fixed a bug where received VJ packets would only
be recognized if INET6 was defined.
