Move the arm call to intr_pic_init_secondary earlier in the secondary CPU
initialisation. This ensures it will complete before signalling to the boot
CPU it has booted. This fixes a race with the GIC where the arm_gic_map may
not be populated before it is used to bind interrupts leading to some
interrupts becoming bound to no CPUs.

- Move the error into Makefile and only apply it when building

WITH_META_MODE: Fix rebuilding maketab outside of build-tools.
The bsd.dep.mk yacc targets rely on only the .c file getting a .meta

that it would be generated with a .meta file. r301285 made it so that
the .h file is never expected to get a .meta file. To keep this
restriction in place add in an extra dependency on the .c file so that
it is generated at this time. It's a hack but the best for the patterns

libgeom.so.5.full:
ln -s libgeom.so.5 libgeom.so
cc -o libgeom.so.5.full *.o
Before, or without, WITH_DEBUG_FILES it is:
libgeom.so.5:
ln -s libgeom.so.5 libgeom.so
cc -o libgeom.so.5 *.o
The problem is that bmake considers the link source for the libgeom.so
link in the libgeom.so.5.full target as being a dependency for
libgeom.so.5.full. That resolves to libgeom.so.5. Thus a cyclic
dependency is created. The result of this is that if libgeom.so.5 is
created with a newer timestamp than libgeom.so.5.full, then
libgeom.so.5.full will be rebuilt on the next build. This causes a
chain reaction of everything in the build relinking, or hitting the
problem itself.
Moving the link creation to the target that actually creates
libgeom.so.5 fixes the problem. The simplest fix here is to just
duplicate the logic.

Do not define __NO_STRICT_ALIGNMENT for armv6. While the requirements
are no longer natural-alignment strict, there are still some restrictions.
FreeBSD network code assumes data is naturally-aligned or is running
on a platform with no restrictions; pointers are not annotated to
indicate the data pointed to may be packed or unaligned. The clang
optimizer can sometimes combine the load or store of a pair of adjacent
32-bit values into a single doubleword load/store, and that operation
requires at least 4-byte alignment. __NO_STRICT_ALIGNMENT can lead
to tcp headers being only 2-byte aligned.
Note that alignment faults remain disabled on armv6, this change reverts
only the defining of the symbol which leads to some overly-agressive code
shortcuts when building common/shared drivers and network code for arm.

Fix inconsistent locking of the swap pager named objects list.
Right now, all modifications of the list are locked by sw_alloc_mtx.
But initial lookup of the object by the handle in swap_pager_alloc()
is not protected by sw_alloc_mtx, which means that
vm_pager_object_lookup() could follow freed pointer.
Create a new named swap object with the OBJT_SWAP type, instead
of OBJT_DEFAULT. With this change, swp_pager_meta_build() never need
to upgrade named OBJT_DEFAULT to OBJT_SWAP (in the other place, we do
not forbid for client code to create named OBJT_DEFAULT objects at
all).
That change allows to remove sw_alloc_mtx and make the list locked by
sw_alloc_sx lock. Update swap_pager_copy() to new locking mode.

anonymous swap objects creation, while a caller ensures that the

Change the default build behavior so we don't compile extra TCP modules by
default. At least initially, the feature to support multiple TCP stacks is
aimed at supporting advanced use cases and TCP development, but it is not
necessarily aimed at a wide audience. Therefore, there is no need to build
and install the extra TCP stacks by default. Instead, the people who are
using or developing this functionality can add the extra option to build/
install the extra TCP stacks.
However, we do want to build the extra TCP stacks as part of test builds
(e.g. LINT or tinderbox) to ensure that developers who are testing their
changes will know that their changes do not break the additional TCP
stack modules.
After this change, a user will need to add WITH_EXTRA_TCP_STACKS=1 to
