also only use 16 u_shorts instead of 32 ints. Also add panic()
calls for under- and overflow of the ks_active members under
DIAGNOSTIC. The MAXBUCKET constant ended up in sys/mallocvar.h
and not sys/param.h, as the latter caused build problems.
Ride the kernel revision bump of my previous change.
per size, and make vmstat report this information under the "Memory
statistics by type" display, which is only printed when the kernel
has been compiled with KMEMSTATS defined, like this:

Since struct malloc_type is user-visible and is changed, bump kernel
revision to 5.99.26.
While it is true that malloc(9) is in general on the path of slowly
being replaced by kmem(9) (kmem_alloc/kmem_free), there remains a
lot of points of usage of malloc/free, and this could aid in finding
any leaks. (It helped finding the leak fixed in PR#42661.)
This was discussed with and somewhat hestitantly OKed by rmind@
most cases, use a proper constructor. For proplib, give a local
equivalent of POOL_INIT for the kernel object implementation. This
way the code structure can be preserved, and a local link set is
not hazardous anyway (unless proplib is split to several modules,
but that'll be the day).
tested by booting a kernel in qemu and compile-testing i386/ALL
(xxx_INIT to xxx_HEAD_INITIALIZER). Drop code which inits
non-auto (global or static) variables to 0 since that's
already implied by being non-auto. Init some static/global
cpu_simple_locks at compile time.
- G/C spinlockmgr() and simple_lock debugging.
- Always include the kernel_lock functions, for LKMs.
- Slightly improved subr_lockdebug code.
- Keep sizeof(struct lock) the same if LOCKDEBUG.
- don't use managed mappings/backing objects for wired memory allocations.
save some resources like pv_entry. also fix (most of) PR/27030.
- simplify kernel memory management API.
- simplify pmap bootstrap of some ports.
- some related cleanups.
