    Remove kmem cache flags from the debugging interface
    
    * include/mach_debug/slab_info.h (CACHE_FLAGS_NO_CPU_POOL,
    CACHE_FLAGS_SLAB_EXTERNAL, CACHE_FLAGS_NO_RECLAIM,
    CACHE_FLAGS_VERIFY, CACHE_FLAGS_DIRECT): Remove macros.
    * kern/slab.c (host_slab_info): Pass raw cache flags to caller.

    Fix slab allocator option handling
    
    The slab allocator has grown to use multiple ways to allocate slabs
    as well as track them, which got a little messy. One consequence is
    the breaking of the KMEM_CF_VERIFY option. In order to make the code
    less confusing, this change expresses all options as explicit cache
    flags and clearly defines their relationships.
    
    The special kmem_slab and vm_map_entry caches are initialized
    accordingly.
    
    * kern/slab.c (KMEM_CF_DIRECTMAP): Rename to ...
    (KMEM_CF_PHYSMEM): ... this new macro.
    (KMEM_CF_DIRECT): Restore macro.
    (KMEM_CF_USE_TREE, KMEM_CF_USE_PAGE): New macros.
    (KMEM_CF_VERIFY): Update value.
    (kmem_pagealloc_directmap): Rename to...
    (kmem_pagealloc_physmem): ... this new function.
    (kmem_pagefree_directmap): Rename to ...
    (kmem_pagefree_physmem): ... this new function.
    (kmem_pagealloc, kmem_pagefree): Update macro names.
    (kmem_slab_use_tree): Remove function.
    (kmem_slab_create, kmem_slab_destroy): Update according to the new
    cache flags.
    (kmem_cache_compute_sizes): Rename to ...
    (kmem_cache_compute_properties): ... this new function, and update
    to properly set cache flags.
    (kmem_cache_init): Update call to kmem_cache_compute_properties.
    (kmem_cache_alloc_from_slab): Check KMEM_CF_USE_TREE instead of
    calling the defunct kmem_slab_use_tree function.
    (kmem_cache_free_to_slab): Update according to the new cache flags.
    kmem_cache_free_verify): Add assertion.
    (slab_init): Update initialization of kmem_slab_cache.
    * kern/slab.h (KMEM_CACHE_DIRECTMAP): Rename to ...
    (KMEM_CACHE_PHYSMEM): ... this new macro.
    * vm/vm_map.c (vm_map_init): Update initialization of vm_map_entry_cache.

commit b325f426b367d813b23799aeb058d7d3ac81f13d

    Optimize slab lookup on the free path
    
    Caches that use external slab data but allocate slabs from the direct
    physical mapping can look up slab data in constant time by associating
    the slab data directly with the underlying page.
    
    * kern/slab.c (kmem_slab_use_tree): Take KMEM_CF_DIRECTMAP into account.
    (kmem_slab_create): Set page private data if relevant.
    (kmem_slab_destroy): Clear page private data if relevant.
    (kmem_cache_free_to_slab): Use page private data if relevant.
    * vm/vm_page.c (vm_page_init_pa): Set `priv' member to NULL.
    * vm/vm_page.h (vm_page_set_priv, vm_page_get_priv): New functions.

    Fix unused variable warnings
    
    * kern/slab.c (slab_init): Remove unused variables.
