- Use cegger@'s ACPI SRAT parsing code to figure out NUMA node ID for each
CPU as it is attached.
- For scheduler experiments with SMT, flag CPUs with the lowest numbered SMT
IDs as "primaries", link back to the primaries from secondaries, and build
a circular list of CPUs in each package with identical SMT IDs.
- No need for package/core/smt/numa IDs to be anything other than a u_int.
doing the tmpfs / MAKEDEV magic.
On images for machines with serious ram shortage (where the additional
tmpfs hurts, like VAX) override this with CDDEV_POPULATE=true.
Should fix PR port-amd64/54776.
The existing "table" output showing device file path of pdev is
not compatible with dm in Linux kernel (and also DragonFlyBSD).
It should be showing "major:minor" instead.

The features is realized by the following operations:
- internal switch
- use "0b00: Show VLAN, DEI and UP in descriptor" mode
- TX
- set VLAN tag and IL2TAG1 flag to each descriptor
- RX
- use 32byte descriptor to use SHOWIV and L2SEL flag
included in RX queue configuration
- VLAN tags are not stored in descriptor without these config.
- get VLAN tags from L2TAG1 field included in RX descriptor
and set them to mbuf

The EFI environment variable `rndseed' specifies the path to the
random seed. It is loaded only for fdt platforms at the moment.
Since the rndseed (an rndsave_t object as defined in <sys/rndio.h>)
is 536 bytes long (for hysterical raisins), and to avoid having to
erase parts of the fdt tree, we load it into a physical page whose
address is passed in the fdt tree, rather than passing the content of
the file as an fdt node directly; the kernel then reserves the page
from uvm, and maps it into kva to call rnd_seed.
For now, the only kernel that does use efiboot with fdt is evbarm,
which knows to handle the rndseed. Any new kernels that use efiboot
with fdt must do the same; otherwise uvm may hand out the page with
the secret key on it for a normal page allocation in the kernel --
which should be OK if there are no kernel memory disclosure bugs, but
would lead to worse consequences than simply loading the seed late in
userland with /etc/rc.d/random_seed otherwise.

Called at end of cpu_startup. Can be defined in, e.g., evbarm to do
additional stuff after cpu_startup. Defined as a weak alias to a
function that does nothing, so optional.

- Fix various locking & sequencing errors with breaking loans.
- Don't call uvm_pageremove_tree() while holding pg->interlock as radixtree
can take further locks when freeing nodes.
