d97889de23 Fix sysctl_createv() so that rnode and cnode can refer to the same 
pointer.  Fix sysctl_create() so that nodes cannot be added to an
alias node.

63fe9ef057 Use proper NetBSD conventions for deferred kthread creation, not the 
other semantics from an earlier incarnation.

Call kcont_init() from init_main before device autoconfiguration,
so kcont is availble to device drivers if required.

Also ensure the kthread process runs any pending continuations once
the kthread is finally up and running. For now, use a non-null timeout
to poll the queue periodically.  Draining any pending requests just
before the kthread enters its ltsleep()/kc_run loop is cleaner, but
this is the version I tested with an early-in-boot kcont request.)

1c13fd358f Give buf_lotsfree() a bit of a service: 
- Fix a 32-bit overflow that could erroneously return true even if the
  currently allocated buffer memory was greater than the high water mark.
- Add an early check for bufmem > hiwater to avoid a needless call to
  random().
- Sprinkle some comments.

Add a vm.bufmem sysctl so the current bufmem value can be easily queried
from userland.

845a217e15 Convert pool_get()'s from nowait to waitok. We're allowed to block, 
and this is more acceptable since the code assumes success.

44afe14cb6 Unwind the nested designators for fields within structs within structs 
(or unions).  This should really be put back once we're all using gcc3
for everything, since that makes it look a *lot* cleaner.

bcb7a96b95 In exec_sigcode_map(), do nothing if the sigcode is of 
size 0.
This way, individual ports can circumvent sigcode mapping
by setting sigcode/esigcode.
(would be better to clean up the __HAVE_SIGINFO/COMPAT_XX
stuff, but it is not a good moment now)
