seq_file.h and linux_seq_file.c was imported form ports earlier but
linux_seq_file.c was never compiled in with the module. With this
commit base seq_file will replace ports seq_file and it required a
few modifications to not break functionality and build.

in RFC 4620, ICMPv6 Node Information Queries. A vnet jail with an
IPv6 address sent a hostname of the host environment, not the
jail, even if another hostname was set to the jail.
This change can be tested by the following commands:
# ifconfig epair0 create
# jail -c -n j1 vnet host.hostname=vnetjail path=/ persist
# ifconfig epair0b vnet j1
# ifconfig epair0a inet6 -ifdisabled auto_linklocal up
# jexec j1 ifconfig epair0b inet6 -ifdisabled auto_linklocal up
# ping6 -w ff02::1%epair0a

Check LINUXKPI_VERSION macro for backwards compatibility.
It's recommended to update any drivers that depend on the older KPI
so we can deprecate < 5.0 code as we update to newer Linux version.

In xdma_handle_mem_node(), vmem_size_t and vmem_addr_t pointers were passed to
an FDT API that emits u_long values to the output parameter pointer. This
broke on systems with both xdma and 32-bit vmem size/addr types (SOCFPGA).

For machines having cmpxcgh16b instruction, i.e. everything but very
early Athlons, provide lockless implementation of delayed
invalidation.
The implementation maintains lock-less single-linked list with the
trick from the T.L. Harris article about volatile mark of the elements
being removed. Double-CAS is used to atomically update both link and
generation. New thread starting DI appends itself to the end of the
queue, setting the generation to the generation of the last element
+1. On DI finish, thread donates its generation to the previous
element. The generation of the fake head of the list is the last
passed DI generation. Basically, the implementation is a queued
spinlock but without spinlock.
Many thanks both to Peter Holm and Mark Johnson for keeping with me
while I produced intermediate versions of the patch.

Use roundup2() and rounddown2() instead of inlining them.
Get rid of the fd local variable, use literal -1 for the mmap argument.
Use MAP_FAILED as mmap(2) failure indicator.
After that, apply some style.

The previous calculations for displaying the time since last switch
easily overflowed, after less than 36 min for hz=1000. Now overflow
takes 2000 times longer (as long as ticks takes to wrap).

A static analyzer complained about a couple instances of checking a
variable against NULL after already having dereferenced it.
- dmar_gas_alloc_region: remove the tautological NULL checks
- dmar_release_resources / dmar_fini_fault_log: don't deref unit->regs
unless initialized.
And while here, fix an inverted initialization check in dmar_fini_qi.

an unknown switch is passed outputting the command usage. This is
because the NDIS driver is uninitialized when usage help is printed.
To resolve this we initialize the driver prior to the possibility of
printing the usage help message.

As of r347410 IPSec is no longer built into GENERIC. The ipsec.ko module must
be loaded before we can execute the IPSec tests.
Check this, and skip the tests if IPSec is not available.
These datasets will generally be canmount=noauto,mountpoint=none (e.g.
zroot/var) but have children that may need to be mounted. Instead of
skipping that segment for no good reason, descend.
