defer their creation to later, so that they are owned by BUILDUSER.
This eliminates the last root-owned files in obj/ from 'make build'.
In addition, place a MACHINE == hppa test in hppa/stand/Makefile.inc
to avoid creating bogus symlinks on all other archs.

it instead.
If anything bad happen due to a malformed descriptor it makes no sense
to try to attach a driver, and bail before probing.
This is similar to the change to avoid calling usbd_set_config_index().

doing requests like that causes lockups on boot.

1) Replace '.elif !exists(${OBJDIR}/Makefile)' with just '.else'. espie
pointed out, that if the file existed, make wouldn't be reading this
file, so the check is superflous. Less clutter.
2) Unconditionally define the 'clean' and 'cleandir' targets, also when
obj doesn't exist. This changes the behaviour of 'make clean' to be
successful (doing nothing) without obj@ or obj/.

This change makes it possible for the Host to update the value
of an existing key via a Set operation as well as to remove the
key completely with a Delete message.

We need to ensure list and data consistency during concurrent
accesses since the interrupt handler is not executed under the
kernel lock and may add or modify entries while userland process
is reading the value or traversing the list.

The implemented abstraction allows us to query and set little
endian UTF-16 keys exchanged between the Host and the Guest via
a text based pvbus(4) interface.
All keys are attached to one of several key pools: Auto, Guest,
External or Guest/Parameters. The hostctl(8) is able to modify
values for keys in the Auto pool as well as set new keys in the
Guest pool while the Host provides its keys in External and
Guest/Parameters pools.

While here, cleanup the kernel output a bit.

Clang static analyser has found that a tsleep was using an uninitialised
pointer value as a wait channel. An associated wakeup wasn't doing the
right thing either.

it copies the existing pool code, except it works on pool_list
structures instead of pool_item structures.
after this id like to poison the words used by the TAILQ_ENTRY in
the pool_list struct that arent used until a list of items is moved
into the global depot.
|
|
it makes it more readable, and fixes a bug in pool_list_put where it
was returning the next item in the current list rather than the next
list to be freed.

this is modelled on whats described in the "Magazines and Vmem:
Extending the Slab Allocator to Many CPUs and Arbitrary Resources"
paper by Jeff Bonwick and Jonathan Adams.
the main semantic borrowed from the paper is the use of two lists
of free pool items on each cpu, and only moving one of the lists
in and out of a global depot of free lists to mitigate against a
cpu thrashing against that global depot.
unlike slabs, pools do not maintain or cache constructed items,
which allows us to use the items themselves to build the free list
rather than having to allocate arrays to point at constructed pool
items.
the per cpu caches are build on top of the cpumem api.
this has been kicked a bit by hrvoje popovski and simon mages (thank you).
im putting it in now so it is easier to work on and test.

instead of hardcoding it. With this we can change the error type to
something else and get a more accurate description of what happened.

return the error code and the return value to signal if the validation
was successful or not. With this we can signal some errors in the spec
that uses the value 0 (zero).

raise the mtu to 9380 bytes so we can take advantage of the extra space.

Further improve vmm's security model by restricting pledged vmm
processes to only do VMM_IOC_ ioctls on their associated VM (these
ioctls are _RUN, _RESETCPU, _INTR, _READREGS, or _WRITEREGS at
present). The vmm monitor (parent) process or any non-pledged
processes can still do ioctls on any VM. For example, a VM can only
terminate itself but vmctl or the monitor can terminate any VM.
This prevents reachover into other VMs: while escaping from a VM to
the host side (eg. through a bug in virtio etc.) pledge already kept
the attacker in a pledged and privsep'ed process, but now it also
prevents vmm ioctls on "other VMs".

now it asks the mbuf layer for the 9k from its pools.
a question from chris@ made me go look at the chip doco again and i
realised that the chip only requires 4 byte alignment for rx buffers,
no 4k alignment for jumbo buffers.
i also found that the chip is supposed to be able to rx up to 9400
bytes instead of 9000. ill fix that later though.

The RTS threshold should be good enough and applies to all modes.
A similar change was made in iwm(4) not long ago.
