Use the two new union types (pam_conv_item_t and

caused by casts to comply with the pam_get_item() API taking
a "const void **" for all item types. Warnings are
generated for casts that create "type puns" (pointers of
conflicting sized types that are set to access the same
memory location) since these pointers may be used in ways
that violate C's strict aliasing rules. Casts to a new
type must be performed through a union in order to be
compliant, and access must be performed through only one
of the union's data types during the lifetime of the union
instance. Handle strict-aliasing warnings through pointer
assignments, which drastically simplifies this change.

Create a new function to complete 802.11 mbuf transmission.
The aim of this function is to eventually be the completion entry point
for all 802.11 encapsulated mbufs. All the wifi drivers end up doing
what is in this function so it's an easy win to turn it into a net80211

Ideally the drivers will all eventually be modified to queue up completed

Introduce superpages support for ARMv6/v7.
Promoting base pages to superpages can increase TLB coverage and allow for
efficient use of page table entries. This development provides FreeBSD/ARM
with superpages management mechanism roughly equivalent to what we have for
i386 and amd64 architectures.
1. Add mechanism for automatic promotion of 4KB page mappings to 1MB section
mappings (and demotion when not needed, respectively).
2. Managed and non-kernel mappings are now superpages-aware.
3. The functionality can be enabled by setting "vm.pmap.sp_enabled" tunable to
a non-zero value (either in loader.conf or by modifying "sp_enabled"
variable in pmap-v6.c file). By default, automatic promotion is currently
disabled.

When we are using memcpy to move objects around, and we fail to memcpy

While working on a new kms driver that uses memcpy, if I overallocated bo's

freeing it a second time didn't end well.
drm/ttm: use ttm_bo_reserve_slowpath_nolru in ttm_eu_reserve_buffers, v2
This requires re-use of the seqno, which increases fairness slightly.
Instead of spinning with a new seqno every time we keep the current one,
but still drop all other reservations we hold. Only when we succeed,
we try to get back our other reservations again.
This should increase fairness slightly as well.
Changes since v1:
- Increase val_seq before calling ttm_bo_reserve_slowpath_nolru and
retrying to take all entries to prevent a race.
With the lru lock no longer required for protecting reservations we
can just do a ttm_bo_reserve_nolru on -EBUSY, and handle all errors
in a single path.
There should no longer be assumptions that reserve will always succeed
with the lru lock held, so we can safely break the whole atomic
reserve/lru thing. As a bonus this fixes most lockdep annotations for
reservations.
