This file provides support to build test programs that comply with the
Test Anything Protocol. Its main goal is to support the painless
integration of existing tests from tools/regression/ into the Kyua-based
test suite.

When the guest is bringing up the APs in the x2APIC mode a write to the
ICR register will now trigger a return to userspace with an exitcode of
VM_EXITCODE_SPINUP_AP. This gets SMP guests working again with x2APIC.
Change the vlapic timer lock to be a spinlock because the vlapic can be
accessed from within a critical section (vm run loop) when guest is using
x2apic mode.

sys/cdefs.h. In particular, in case of COMPAT_43, param.h includes
sys/types.h, which includes sys/select.h, which includes
sys/_sigset.h. The _sigset.h customizes the provided definions based
on COMPAT_43, eliminating osigset_t if symbol is not defined. The
sys/proc.h is included after opt_compat.h and needs osigset_t.
Move opt_compat.h inclusion into the right place.

the excess code in g_io_check(), bio_resid is also truncated by
g_io_deliver(). As result, bufdonebio() assigns truncated value to
the buffer b_resid field.
Use the residual bio_completed to calculate buffer b_resid from
b_bcount in bufdonebio(), instead of bio_resid, calculated from
bio_length in g_io_deliver().
The issue is seemingly caused by the code rearrange into g_io_check(),
which is not present in stable/10. The change still looks as the
useful change to have in 10 nevertheless.

the bio is unmapped, so we must map the bio pages into pbuf. This
works around the geom classes which do not follow the MAXPHYS limit on
the i/o size, since such classes do not know about unmapped bios
either.

Intel manual says: "If a transition is already in progress, transition to
a new value will subsequently take effect. Reads of IA32_PERF_CTL determine
the last targeted operating point." So seems it should be fine to just
trigger wanted transition and go. Linux does the same.

request back from the receive queue -- it might already be processed
by remote_recv_thread, which lead to crashes like below:
(primary) Unable to receive reply header: Connection reset by peer.
(primary) Unable to send request (Connection reset by peer):
WRITE(954662912, 131072).
(primary) Disconnected from kopusha:7772.
(primary) Increasing localcnt to 1.
(primary) Assertion failed: (old > 0), function refcnt_release,

Taking the request back was not necessary (it would properly be
processed by the remote_recv_thread) and only complicated things.

indication when a request can be moved to done queue, but also for
detecting the current state of memsync request.
This approach has problems, e.g. leaking a request if memsynk ack from
the secondary failed, or racy usage of write_complete, which should be
called only once per write request, but for memsync can be entered by
local_send_thread and ggate_send_thread simultaneously.
So the following approach is implemented instead:
1) Use hio_countdown only for counting components we waiting to
complete, i.e. initially it is always 2 for any replication mode.
2) To distinguish between "memsync ack" and "memsync fin" responses
from the secondary, add and use hio_memsyncacked field.
3) write_complete() in component threads is called only before
releasing hio_countdown (i.e. before the hio may be returned to the
done queue).
4) Add and use hio_writecount refcounter to detect when
write_complete() can be called in memsync case.

1.44MB floppy, though it is not very practical and quite slow.
The An macros is used for authors while the Ar macro is used for arguments.
AFAIK mcast-addr and ifname are not authors.
