UVM locking changes, proposed on tech-kern:

Load struct filedesc::fd_dt with atomic_load_consume.

Exceptions: when fd_refcnt <= 1, or when holding fd_lock.

While here:

- Restore KASSERT(mutex_owned(&fdp->fd_lock)) in fd_unused.
  => This is used only in fd_close and fd_abort, where it holds.
- Move bounds check assertion in fd_putfile to where it matters.
- Store fd_dt with atomic_store_release.
- Move load of fd_dt under lock in knote_fdclose.
- Omit membar_consumer in fdesc_readdir.
  => atomic_load_consume serves the same purpose now.
  => Was needed only on alpha anyway.

Refactor pipe1() and correct a bug in sys_pipe2() (SYS_pipe2)

sys_pipe2() returns two integers (values), the 2nd one is a copy of the 2nd
file descriptor that lands in fildes[2]. This is a side effect of reusing
the code for sys_pipe() (SYS_pipe) and not cleaning it up.

The first returned value is (on success) 0.

Introduced a small refactoring in pipe1() that it does not operate over
retval[], but on an array int[2]. A user sets retval[] for pipe() when
desired and needed.

This refactoring touches compat code: netbsd32, linux, linux32.

Before the changes on NetBSD/amd64:

$ ktruss -i ./a.out
[...]
 15131      1 a.out    pipe2(0x7f7fff2e62b8, 0)    = 0, 4
[...]

After the changes:

$ ktruss -i ./a.out
[...]
   782      1 a.out    pipe2(0x7f7fff97e850, 0)    = 0
[...]

There should not be a visible change for current users.

Initial snapshot of work to eliminate 64K MAXPHYS.  Basically works for
physio (I/O to raw devices); needs more doing to get it going with the
filesystems, but it shouldn't damage data.

All work's been done on amd64 so far.  Not hard to add support to other
ports.  If others want to pitch in, one very helpful thing would be to
sort out when and how IDE disks can do 128K or larger transfers, and
adjust the various PCI IDE (or at least ahcisata) drivers and wd.c
accordingly -- it would make testing much easier.  Another very helpful
thing would be to implement a smart minphys() for RAIDframe along the
lines detailed in the MAXPHYS-NOTES file.

Force sys_close not to restart by returning ERESTART.

Print a diagnostic message if we ever get ERESTART out of fd_close
and convert it to EINTR instead.

Even if fd_close fails, it has already closed the file descriptor, so
restarting the system call is a mistake, with dangerous consequences
for multithreaded programs.

Should probably turn the message into a kassert eventually, and maybe
add one deeper in fd_close in order to more easily debug it before
all the data structures are destroyed.

* Arrange for interfaces that create new file descriptors to be able to
  set close-on-exec on creation (http://udrepper.livejournal.com/20407.html).

    - Add F_DUPFD_CLOEXEC to fcntl(2).
    - Add MSG_CMSG_CLOEXEC to recvmsg(2) for unix file descriptor passing.
    - Add dup3(2) syscall with a flags argument for O_CLOEXEC, O_NONBLOCK.
    - Add pipe2(2) syscall with a flags argument for O_CLOEXEC, O_NONBLOCK.
    - Add flags SOCK_CLOEXEC, SOCK_NONBLOCK to the socket type parameter
      for socket(2) and socketpair(2).
    - Add new paccept(2) syscall that takes an additional sigset_t to alter
      the sigmask temporarily and a flags argument to set SOCK_CLOEXEC,
      SOCK_NONBLOCK.
    - Add new mode character 'e' to fopen(3) and popen(3) to open pipes
      and file descriptors for close on exec.
    - Add new kqueue1(2) syscall with a new flags argument to open the
      kqueue file descriptor with O_CLOEXEC, O_NONBLOCK.

* Fix the system calls that take socklen_t arguments to actually do so.

* Don't include userland header files (signal.h) from system header files
  (rump_syscallargs.h).

* Bump libc version for the new syscalls.

Welcome to 5.99.53!  Merge rmind-uvmplock branch:

- Reorganize locking in UVM and provide extra serialisation for pmap(9).
  New lock order: [vmpage-owner-lock] -> pmap-lock.

- Simplify locking in some pmap(9) modules by removing P->V locking.

- Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share
  the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs).

- Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner.
  Add TLBSTATS option for x86 to collect statistics about TLB shootdowns.

- Unify /dev/mem et al in MI code and provide required locking (removes
  kernel-lock on some ports).  Also, avoid cache-aliasing issues.

Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches
formed the core changes of this branch.

More changes to improve kern_descrip.c.

- Avoid atomics in more places.
- Remove the per-descriptor mutex, and just use filedesc_t::fd_lock.
  It was only being used to synchronize close, and in any case we needed
  to take fd_lock to free the descriptor slot.
- Optimize certain paths for the <NDFDFILE case.
- Sprinkle more comments and assertions.
- Cache more stuff in filedesc_t.
- Fix numerous minor bugs spotted along the way.
- Restructure how the open files array is maintained, for clarity and so
  that we can eliminate the membar_consumer() call in fd_getfile().  This is
  mostly syntactic sugar; the main functional change is that fd_nfiles now
  lives alongside the open file array.

Some measurements with libmicro:

- simple file syscalls are like close() are between 1 to 10% faster.
- some nice improvements, e.g. poll(1000) which is ~50% faster.

Merge proc::p_mutex and proc::p_smutex into a single adaptive mutex, since
we no longer need to guard against access from hardware interrupt handlers.

Additionally, if cloning a process with CLONE_SIGHAND, arrange to have the
child process share the parent's lock so that signal state may be kept in
sync. Partially addresses PR kern/37437.

File descriptor changes, discussed on tech-kern:

- Redo reference counting to be sane.  LWPs accessing files take a short
  term reference on the local file descriptor.  This is the most common
  case.  While a file is in a process descriptor table, a reference is
  held to the file.  The file reference count only changes during control
  operations like open() or close().  Code that comes at files from an
  unusual direction (i.e. foreign to the process) like procfs or sysctl
  takes a reference on the file (f_count), and not on a descriptor.

- Remove knowledge of reference counting and locking from most code that
  deals with files.

- Make the usual case of file descriptor lookup lockless.

- Make kqueue MP and MT safe. PR kern/38098, PR kern/38137.

- Fix numerous file handling bugs, and bugs in the descriptor code that
  affected multithreaded processes.

- Split descriptor system calls out into sys_descrip.c.

- A few stylistic changes: KNF, remove unused casts now that caddr_t is
  gone. Replace dumb gotos with loop control in a few places.

- Don't do redundant pointer passing (struct proc, lwp, filedesc *) unless
  the routine is likely to be inlined.  Most of the time it's about the
  current process.
