The real cause for removing asm inline code on clang is that the
"r" constraint cannot handle 64-bit and is treated as 32-bit.

So code that refers to the upper 32-bit (manuf or impl) of the %ver
register is removed by optimization.

Use 32-bit kernel code as a workaround when referring to the %ver
register.

Centralized shared part of child_return() into MI part

Add a new function md_child_return() for MD specific bits only.

New child_return() is now part of MI and central code that handles

Synchronize value passed to ktrsysret() among ports to SYS_fork. This is
a traditional value and accessing p_lflag to check for PL_PPWAIT shall
use locking against proc_lock. Returning SYS_fork vs SYS_vfork still isn't
correct enough as there are more entry points to forking code. Instead of
making it too good, just settle with plain SYS_fork for all ports.

Overhaul the API used to fetch and store individual memory cells in
userspace.  The old fetch(9) and store(9) APIs (fubyte(), fuword(),
subyte(), suword(), etc.) are retired and replaced with new ufetch(9)
and ustore(9) APIs that can return proper error codes, etc. and are
implemented consistently across all platforms.  The interrupt-safe
variants are no longer supported (and several of the existing attempts
at fuswintr(), etc. were buggy and not actually interrupt-safe).

Also augmement the ucas(9) API, making it consistently available on
all plaforms, supporting uniprocessor and multiprocessor systems, even
those that do not have CAS or LL/SC primitives.

Add __clone(2) tests in t_ptrace_wait*

The __clone(2) API is a variation of fork(2)/vfork(2) operations.

- clone_vm_signalmasked
- clone_fs_signalignored
- clone_fs_signalmasked
- clone_files_signalignored
- clone_files_signalmasked
- clone_vfork_signalignored
- clone_vfork_signalmasked

All new tests pass.

CLONE_SIGHAND tests are right now disabled as they cannot reuse the shared
signal operations (wait(2)) to wait for a clonee.

Another nit is that wait(2) must be used right now with WALLSIG as for some
reason the default variation doesn't work.

Implement a DIRTY flag (copied from sd(4)) so avoid flushing the cache if
there has been no write. This avoids a (long) timeout on the flush cache
command triggered by atactl sleep, when the device is open only by the atactl
command itself.
If a drive has no partition open and goes to sleep, the WDF_LOADED
flag is clear, and the next open will issue  wd_get_params() command.
But to wake up the drive a reset is required, and wd_get_params() doens't
issue a reset on timeout, so there's no way to wake up the disk.
Add a retry after reset to wd_get_params().

Fix a tiny race in setregs and linux_setregs. Between the moment we set
pcb_flags to zero, and the moment cpu_segregs64_zero resets pcb_gs, we may
be preempted.

If this happens, and if the calling LWP was a 32bit thread, when switching
back to that LWP, the context switcher sees that PCB_COMPAT32 is not set in
pcb_flags and tries to perform a 64bit context switch; but pcb_gs contains
a 32bit GDT descriptor, and not a 64bit GS.base value. The wrmsr therefore
faults because the value is non-canonical, and this fault is fatal.

Rearrange the code so that the update of pcb_flags and pcb_gs/pcb_fs is non
interruptible. This fixes the problem, tested with a reproducer (which
therefore doesn't work anymore).

Likely fixes PR/53993.

Disable preemption when setting PCB_COMPAT32, to prevent a context switch
before cpu_fsgs_reload() finishes, otherwise we write garbage in the GDT.

On NetBSD-current it is harmless, however in NetBSD-8 it might cause
panics, because NetBSD-8 uses the old SegRegs model and under this model
we reload %fs and %gs during switches.

  Changes to code

    zic now has an -r option to limit the time range of output data.
    For example, 'zic -r @1000000000' limits the output data to
    timestamps starting 1000000000 seconds after the Epoch.
    This helps shrink output size and can be useful for applications
    not needing the full timestamp history, such as TZDIST truncation;
    see Internet RFC 8536 section 5.1.  (Inspired by a feature request
    from Christopher Wong, helped along by bug reports from Wong and
    from Tim Parenti.)

FreeBSD actively maintains this program in their sources and their

Keep the delta between the FreeBSD and NetBSD versions to absolute

- Added option -P for loading user-provided files as profiles
- Added -tsn for setting tabsize
- Rename -nsac/-sac ("space after cast") to -ncs/-cs
- Added option -fbs Enables (disables) splitting the function declaration and opening brace across two lines.
- Respect SIMPLE_BACKUP_SUFFIX environment variable in indent(1)
- Group global option variables into an options structure
- Use bsearch() for looking up type keywords.
- Don't produce unneeded space character in function declarators
- Don't unnecessarily add a blank before a comment ends.
- Don't ignore newlines after comments that follow braces.

Merge the FreeBSD intend(1) tests with our ATF framework.

  IXGBE_DCB_MAX_TRAFFIC_CLASS (e.g. 1), other traffic classes' counters
