vm_pager_init() is run before required nswbuf variable has been set
to correct value. This caused system to run with single pbuf available
for vnode_pager. Handle both cluster_pbuf_freecnt and vnode_pbuf_freecnt
variableis in the same way.

Move MAC check_vnode_mmap entry point out from being exclusive to
MAP_SHARED so that the entry point gets executed un-conditionally.
This may be useful for security policies which want to perform access
control checks around run-time linking.
-add the mmap(2) flags argument to the check_vnode_mmap entry point
so that we can make access control decisions based on the type of
mapped object.
-update any dependent API around this parameter addition such as
function prototype modifications, entry point parameter additions
and the inclusion of sys/mman.h header file.
-Change the MLS, BIBA and LOMAC security policies so that subject
domination routines are not executed unless the type of mapping is
shared. This is done to maintain compatibility between the old
vm_mmap_vnode(9) and these policies.

Add the vm.exec_map_entries tunable and read-only sysctl, which controls
the number of entries in exec_map (maximum number of simultaneous execs
that can be handled by the kernel). The default value of 16 is
insufficient on heavily loaded machines (particularly SMP machines), and
if it is exceeded then executing further processes will generate a SIGABRT.
This is a workaround until a better solution can be implemented.

Move the swap_zone == NULL check earlier (i.e. before we dereference
the pointer.)

Assert that page allocations during an interrupt specify
VM_ALLOC_INTERRUPT.
Assert that pages removed from the cache queue are not busy.
MFC revision 1.303
Transfer responsibility for freeing the page taken from the cache
queue and (possibly) unlocking the containing object from
vm_page_alloc() to vm_page_select_cache().
