process with redirects. If we use vfork() and a redirect hangs
(eg: opening a fifo) which the parent was intended to unhang,
then the parent never gets to continue to unhang the child.
eg: mkfifo f; cat <f &; echo foo>f
The parent should not be waiting for a background process, even
just for its exec() to complete. if there are no redirects there
is (should be) nothing left that might be done that will cause any
noticeable delay, so vfork() should be safe in all other cases.
As mentioned in "dm: Don't try to implement "status" as subset of "table"",
dm-stripe in NetBSD doesn't have correct "status" output format.
Implement ->info() to sync with Linux kernel.
Note that num_error for stripe device isn't implemented yet.

- Have a single lock (uvmpd_lock) to protect pagedaemon state that was
previously covered by uvmpd_pool_drain_lock plus uvm_fpageqlock.
- Don't require any locks be held when calling uvm_kick_pdaemon().
- Use uvm_free().
something else soon and TBH it matches what this macro does better.
- Add inlines to set/get locator values in the unused lower bits of
pg->phys_addr. Begin by using it to cache the freelist index, because
computing it is expensive and that shows up during profiling. Discussed
on tech-kern.
Retrieving device dependencies doesn't need to be target specific.
The reason it currently needs ->deps() is because dm core doesn't
have data structure that allows table to walk through target's
underlying devices. Add struct dm_mapping to be able to do this,
and remove ->deps()'s from targets which basically do the same thing.

- 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
