c21fd23260 Always compile PFIL_HOOKS into the kernel and remove the associated kernel 
compile option.  All FreeBSD packet filters now use the PFIL_HOOKS API and
thus it becomes a standard part of the network stack.

If no hooks are connected the entire packet filter hooks section and related
activities are jumped over.  This removes any performance impact if no hooks
are active.

Both OpenBSD and DragonFlyBSD have integrated PFIL_HOOKS permanently as well.

4d855643d1 Clarify what the lockfunc is used for. When it will be called and 
when it won't be called.  The old wording was correct, but not
sufficiently specific to understand when and how it would be called.
The new wording describes the current implementation's usage (which
should be updated if other appropriate times are decided upon),
specifically that it is called only when the load operation is
deferred to keep the locking state consistent.  When the operation
isn't deferred, the calling routine is assumed to have a coherent
locking world.

95929b661e Even in a 80 column, fixed point font, there's plenty of room for all 
the arguments to bus_dmamap_load, so don't use '...' but list the
actual args.  '...' usually means a variable number of args (cf
printf(3)), but bus_dmamap_load takes a fixed number of arguments.

cbfef69c64 In the SYNOPSIS section, move the bus_dmamem_alloc function prototype 
to just before bus_dmamem_free, which is (a) more logical; (b) likely
what was originally intended and (c) matches the order in the NAME and
FUNCTIONS sections.

51385a3c00 - Add two fields to bio structure: 'bio_cflags' which can be used by 
consumer and 'bio_pflags' which can be used by provider.
- Remove BIO_FLAG1 and BIO_FLAG2 flags. From now on new fields should be
  used for internal flags.
- Update g_bio(9) manual page.
- Update some comments.
- Update GEOM_MIRROR, which was the only one using BIO_FLAGs.

56f21b9d74 Rename suser_cred()'s PRISON_ROOT flag to SUSER_ALLOWJAIL. This is 
somewhat clearer, but more importantly allows for a consistent naming
scheme for suser_cred flags.

hear any complaints...)

65a311fcb2 Give kldunload a -f(orce) argument. 
Add a MOD_QUIESCE event for modules.  This should return error (EBUSY)
of the module is in use.

MOD_UNLOAD should now only fail if it is impossible (as opposed to
inconvenient) to unload the module.  Valid reasons are memory references
into the module which cannot be tracked down and eliminated.

When kldunloading, we abandon if MOD_UNLOAD fails, and if -force is
not given, MOD_QUIESCE failing will also prevent the unload.

For backwards compatibility, we treat EOPNOTSUPP from MOD_QUIESCE as
success.

Document that modules should return EOPNOTSUPP for unknown events.
