73157b0e11 - Support two different sizes of pool_cache group. The default has 14 or 15 
items, and the new large groups (for busy caches) have 62 or 63 items.
- Add PR_LARGECACHE flag as a hint that a pool_cache should use large groups.
  This should be eventually be tuned at runtime.
- Report group size for vmstat -C.

7e2790cf6f Convert all the system call entry points from: 
int foo(struct lwp *l, void *v, register_t *retval)
to:
    int foo(struct lwp *l, const struct foo_args *uap, register_t *retval)
Fixup compat code to not write into 'uap' and (in some cases) to actually
pass a correctly formatted 'uap' structure with the right name to the
next routine.
A few 'compat' routines that just call standard ones have been deleted.
All the 'compat' code compiles (along with the kernels required to test
build it).
98% done by automated scripts.

2bfef6f106 Add config_deferred() for forcing the deferred configuration to 
run, which we need to do from drvctl(4) sometimes.

Add device_foreach_child() for calling a function on each child of
a device_t.

Add config_detach_children() for detaching all of the children of
a device (uses device_foreach_child()).

e692a6c76a Introduce pmf_system_bus_resume. In the ACPI S3 resume path, use this to 
separate powering up devices from restoring their state. This is required
on some machines where AcpiLeaveSleepState can fail due to an attempt to
access a powered off device.

9725bcfd97 - Use KAUTH_ARG() instead of casts, 
- Don't ignore return value of settime() in sysctl_kern_rtc_offset(), as
  suggested by yamt@.

Note: the kauth(9) call in sysctl_kern_rtc_offset() is bogus, but this will
be addressed separately.

e23d4a9b80 Nothing uses shared -> exclusive upgrades any more, so remove the code. 
This is good since they are effectively the same as ...

	lockmgr(&lock, LK_RELEASE);
	lockmgr(&lock, LK_EXCLUSIVE);

.. and therefore don't behave as expected.

4e38160d4d Do not "return 1" from kqfilter for errors. That value is passed 
directly to the userland caller and results in a mysterious EPERM.
Instead, return EINVAL or something else sensible depending on the

8cd835a351 pool_init, pool_cache_init: hack around IP input processing which can 
not yet safely block without severely confusing soo_write() and friends.
If the pool's IPL is IPL_SOFTNET, initialize the mutex at IPL_VM so that
it's a spinlock. To be dealt with correctly in the near future.
