4ad648d8b4 The smp_rendezvous_cpus() function should ensure that all accesses
done by the functions called on other CPUs, are visible to the caller.
Pair otherwise useless acquire on smp_rv_waiters[3] with a release add
to ensure synchronized with relation, which guarantees visibility.

174d031976 nvd: set d_delmaxsize to full capacity of NVMe namespace
The NVMe specification has no ability to specify a maximum delete size
that is less than the full capacity of the namespace - so just using the
namespace size is the correct value here.

This fixes reported issues where ZFS trim on init looked like it was
hanging the system - previously the default I/O max size (128KB on
Intel NVMe controllers) was used for delete operations which worked out
to only about 8MB/s.  With this patch I can add an 800GB DC P3700
drive to a ZFS pool in about 15-20 seconds.

b1cbea0622 vt: Draw logos per CPU core
This feature is inspired by another Unix-alike OS commonly found on
airplane headrests.

A number of beasties[0] are drawn at top of framebuffer during boot,
based on the number of active SMP CPUs[1]. Console buffer output
continues to scroll in the screen area below beastie(s)[2].

After some time[3] has passed, the beasties are erased leaving the
entire terminal for use.

Includes two 80x80 vga16 beastie graphics and an 80x80 vga16 orb
graphic. (The graphics are RLE compressed to save some space -- 3x 3200
bytes uncompressed, or 4208 compressed.)

[0]: The user may select the style of beastie with

    kern.vt.splash_cpu_style=(0|1|2)

[1]: Or the number may be overridden with tunable kern.vt.splash_ncpu.
[2]: https://www.youtube.com/watch?v=UP2jizfr3_o
[3]: Configurable with kern.vt.splash_cpu_duration (seconds, def. 10).

34b957f11d Don't allow malloc() to wait for resource while holding a lock in ITS
malloc() should not go to sleep in case of lack of resource while
the kernel thread is holding a non-sleepable lock.

- change malloc() flags to M_NOWAIT in such cases implement
  lpi_free_chunk() routine as it will be needed when ITT
  allocation fails in its_device_alloc_locked()
- do not increase verbosity of this code since upper layers will

5f08ac18d2 Make clock_gettime() and clock_getres() work for CloudABI programs.
Though the standard C library uses a 'struct timespec' using a 64-bit
'time_t', there is no need to use such a type at the system call level.
CloudABI uses a simple 64-bit unsigned timestamp in nanoseconds. This is
sufficient to express any time value from 1970 to 2554.

The CloudABI low-level interface also supports fetching timestamp values
with a lower precision. Instead of overloading the clock ID argument for
this purpose, the system call provides a precision argument that may be
used to specify the maximum slack. The current system call
implementation does not use this information, but it's good to already
have this available.

Expose cloudabi_convert_timespec(), as we're going to need this for
fstat() as well.

5b106acac6 Make thread creation work for CloudABI processes.
Summary:
Remove the stub system call that was put in place during the system call
import and replace it by a target-dependent version stored in sys/amd64.
Initialize the thread in a way similar to cpu_set_upcall_kse(). We
provide the entry point with two arguments: the thread ID and the
argument pointer.

Test Plan:
Thread creation still seems to work, both for FreeBSD and CloudABI
binaries.

e4870a15db When a tunneling protocol is being used with UDP we must release the
lock on the INP before calling the tunnel protocol, else a LOR
may occur (it does with SCTP for sure). Instead we must acquire a
ref count and release the lock, taking care to allow for the case
where the UDP socket has gone away and *not* unlocking since the
refcnt decrement on the inp will do the unlock in that case.

3200268ec4 Make forking of CloudABI processes work.
Just like FreeBSD+Capsicum, CloudABI uses process descriptors. Return
the file descriptor number to the parent process.

To the child process we both return a special value for the file
descriptor number (CLOUDABI_PROCESS_CHILD). We also return the thread ID
of the new thread in the copied process, so the threading library can
reinitialize itself.

7f556435bf Add an API for easily creating userspace threads in kernelspace.
This change refactors the existing create_thread() function to be more
generic. It replaces almost all of its arguments by a callback that can
be used to extract the thread ID and copy it out to the right place, but
also to perform additional initialization steps, such as setting the
trapframe. This also makes the difference between thr_new() and
thr_create() more clear in my opinion.

This function is going to be used by the CloudABI compatibility layer.

It looks like the OpenSolaris compatibility framework already provides a
function called thread_create(). Rename this function to
do_thread_create() and use a macro to deal with the namespacing
conflict. A similar approach is already used for thread_exit().
