897d81a020 Do not call vm_object_deallocate() from vm_map_delete(), because we
hold the map lock there, and might need the vnode lock for OBJT_VNODE
objects. Postpone object deallocation until caller of vm_map_delete()
drops the map lock. Link the map entries to be freed into the freelist,
that is released by the new helper function vm_map_entry_free_freelist().

e53fa61bf2 In vm_map_sync(), do not call vm_object_sync() while holding map lock.
Reference object, drop the map lock, and then call vm_object_sync().
The object sync might require vnode lock for OBJT_VNODE type objects.

d2bf64c309 Do not sleep for vnode lock while holding map lock in vm_fault. Try to
acquire vnode lock for OBJT_VNODE object after map lock is dropped.
Because we have the busy page(s) in the object, sleeping there would
result in deadlock with vnode resize. Try to get lock without sleeping,
and, if the attempt failed, drop the state, lock the vnode, and restart
the fault handler from the start with already locked vnode.

Because the vnode_pager_lock() function is inlined in vm_fault(),
axe it.

0dd9f21c23 Prefer the start and end attributes over the offset and size
attributes. The start and end more accurately describe the
space taken by a partition. The offset and size are used to
describe the effective (usable) storage of that partition.

165651a553 o Add the "PART::scheme" attribute that returns the name of the
underlying partitioning scheme.
o  Put the start and end of the partition in the XML configuration.
   The start and end are the LBAs of the first and last sector
   (resp.) of the partition. They are currently identical to the
   offset and size attributes, which describe the partition as an
   offset and size in bytes, but may not in the future. The start
   and end will be used for the logical partition boundaries and
   may include metadata. The offset and size will always represent
   the useful storage space within the partition. Typically these
   two notions are the same, but for logical partitions in an
   extended partition, the EBR is more naturally treated as being
   part of the partition.

7fd10fb3c7 Add the comments to vm_map_simplify_entry() and vmspace_fork(),
describing why several calls to vm_deallocate_object() with locked map
do not result in the acquisition of the vnode lock after map lock.

1fac7d7f35 Lock the new map in vmspace_fork(). The newly allocated map should not
be accessible outside vmspace_fork() yet, but locking it would satisfy
the protocol of the vm_map_entry_link() and other functions called
from vmspace_fork().

Use trylock that is supposedly cannot fail, to silence WITNESS warning
of the nested acquisition of the sx lock with the same name.

97aa4a517a Try to remove/assimilate as much of formerly IPv4/6 specific
(duplicate) code in sys/netipsec/ipsec.c and fold it into
common, INET/6 independent functions.

The file local functions ipsec4_setspidx_inpcb() and
ipsec6_setspidx_inpcb() were 1:1 identical after the change
in r186528. Rename to ipsec_setspidx_inpcb() and remove the
duplicate.

Public functions ipsec[46]_get_policy() were 1:1 identical.
Remove one copy and merge in the factored out code from
ipsec_get_policy() into the other. The public function left
is now called ipsec_get_policy() and callers were adapted.

Public functions ipsec[46]_set_policy() were 1:1 identical.
Rename file local ipsec_set_policy() function to
ipsec_set_policy_internal().
Remove one copy of the public functions, rename the other
to ipsec_set_policy() and adapt callers.

Public functions ipsec[46]_hdrsiz() were logically identical
(ignoring one questionable assert in the v6 version).
Rename the file local ipsec_hdrsiz() to ipsec_hdrsiz_internal(),
the public function to ipsec_hdrsiz(), remove the duplicate
copy and adapt the callers.
The v6 version had been unused anyway. Cleanup comments.

Public functions ipsec[46]_in_reject() were logically identical
apart from statistics. Move the common code into a file local
ipsec46_in_reject() leaving vimage+statistics in small AF specific
wrapper functions. Note: unfortunately we already have a public
ipsec_in_reject().
