   Sync with FreeBSD ix-3.3.8 part 2:
   - Add missing XFI support into ixgbe_get_link_capabilities_X550em().

   Sync with FreeBSD ix-3.3.8 part 1. No functional change in this part:
    - Move ixgbe_toggle_txdctl() to ixgbe_common.c and modify a bit.
      No functional change because this function is currently used for SR-IOV
      and it's not used in NetBSD.
    - Some modification to match the latest netmap API.
    - Modify ixgbe_hic_unlocked(). No functional change because neither
      IXGBE_HOST_INTERFACE_APPLY_UPDATE_CMD(0x38) nor
      IXGBE_HOST_INTERFACE_SHADOW_RAM_READ_CMD(0x31) are used.
    - Add ixgbe_clear_mbx(). No functional change because this function is not
      used yet.
    - Add some not-yet-used register definitions.
    - Whitespace fixes.

   This actually needs the netbsd32 stuff present since the struct for the
   32 bit syscall has a netbsd32_voidp... This header is used also for
   compat/common, so just revert (helped us to fix a bug though :-)

   Include the right stuff so compat_netbsd32_50 compiles.

   Although this is correct, I will let maxv commit it. Still waiting.

   don't cast void *

   Always include the 32 bit structure and definitions on _LP64 regardless
   of compat32 being on or off, because we want the headers to work when
   compiling modular kernels. Of course the 32 bit structs do not make sense
   on platforms that don't have 32 bit modes (alpha), but we don't have
   a define for that and it does not hurt.

   Remove unused field

   Change how we detect secure vs non-secure access.

   Write 0xff to ICC_PMR_EL1 and read back how many bits are implemented,
   then do the same with a GICD_IPRIORITYR<n> priority value field.

   If the values differ, assume we have a shifted view of IPRIORITYR.

   Fix typos

   Some were found by OpenBSD.

   Enable beep test, return is correct.

   make this compile again

   Remove useless debugging messages which achieved nothing but hiding bugs.

   Note import of dhcpcd-7.2.3

   Sync

   Import dhcpcd-7.2.3 with the following changes:
     *  BSD: Check RTM lengths incase of kernel issues
     *  DHCP6: Don't stop even when last router goes away
     *  DHCP6: Fix inform from RA
     *  hostname: Fix short hostname check

   Remove extra if_register() call.
   Move temporary call to vap_create() to end of attach to make sure
   attach works when vap_create() will not be called as part of attach.

   Conform to RFC 3128 by dropping TCP fragments with offset = 1.
   In addition to dropping these fragments, add a DTrace probe to allow
   for more detailed monitoring and diagnosis if required.
   From FreeBSD r349399, reported vy Cy Schubert

   Remove fd_local, it is not used, from FreeBSD r349401, reported by Cy Schubert

   Remove redundant off != 0 check, from FreeBSD r349400, reported by Cy Schubert

   Use Vt for variable types. New sentence, new line. Add a missing ')'.
   Add/remove some articles or other missing words.

   Implement PT_GETXSTATE and PT_SETXSTATE

   Introduce two new ptrace() requests: PT_GETXSTATE and PT_SETXSTATE,
   that provide access to the extended (and extensible) set of FPU
   registers on amd64 and i386.  At the moment, this covers AVX (YMM)
   and AVX-512 (ZMM, opmask) registers.  It can be easily extended
   to cover further register types without breaking backwards
   compatibility.

   PT_GETXSTATE issues the XSAVE instruction with all kernel-supported
   extended components enabled.  The data is copied into 'struct xstate'
   (which -- unlike the XSAVE area itself -- has stable format
   and offsets).

   PT_SETXSTATE issues the XRSTOR instruction to restore the register
   values from user-provided 'struct xstate'.  The function replaces only
   the specific XSAVE components that are listed in 'xs_rfbm' field,
   making it possible to issue partial updates.

   Both syscalls take a 'struct iovec' pointer rather than a direct
   argument.  This requires the caller to explicitly specify the buffer
   size.  As a result, existing code will continue to work correctly
   when the structure is extended (performing partial reads/updates).

   Fetch XSAVE area component offsets and sizes when initializing x86 CPU

   Introduce two new arrays, x86_xsave_offsets and x86_xsave_sizes,
   and initialize them with XSAVE area component offsets and sizes queried
   via CPUID.  This will be needed to implement getters and setters for
   additional register types.

   While at it, add XSAVE_* constants corresponding to specific XSAVE
   components.

   Fix return value.  fo_poll expects revents, not errno.

   Style fixes.  No functional changes intended.
   - Rename some functions for consistency.
   - Rearrange some functions for readability.
   - Unify to struct pad_softc.

   import new CDDL dtrace and ZFS code from FreeBSD svn r315983

   Add files missing from the initial import.

   Fix updating "Multiple Message Enable" field for MSI multiple vectors. Pointed out by 
jmcneill at n.o, thanks.

   I tested ahcisata for MSI single vector regression.

   Initial revision

   Improve debug message and remove duplicated one.

   Bump ramdisk slightly (non MKREPRO builds with long paths fail otherwise)

   Improve audiobell (and interfaces with audio).
   - Generate pseudo sine wave if possible.  It may improve timbre.
     If it cannot represent a sine wave, it falls back to a triangular
     wave or a rectangular wave.
   - Volume adjustment.
   - Calculate playback frequency based on mixer frequency.
     Now audiobellopen() initializes playback parameters other than
     sample_rate, and new audiobellsetrate() sets sample_rate.

   Similar to changes made for x86, allow for the boot-loader to auto-push
   a list of modules for file-system support.  This allows, for example,
   booting from an ext2fs file-system when the kernel has no built-in ufs
   or ext2fs modules.

   XXX Untested, as I have no sandpoint hardware.  I'd appreciate it if
   XXX someone with hardware can build and test.

   whitespace around operators

   Honour _CRS mem ranges and translation offsets instead of assuming 1:1
   mappings. Tested on Overdrive 1000.

   Fixed mvscanw test but leave disabled for the moment, the return for
   mvscanw is incorrect in libcurses, we need a major lib version bump
   to correct it.

   Fail if getcwd fails. Pointed out by maxv@

   s/cpulwp/curlwp/

   Do the fmtcheck for both message lookups to satisfy format string
   literal checks.

   Fix word (direct -> directory) in comment.

   add a comment explaining what this does.

   Fix buffer overflow. It seems that some people need to go back to the
   basics of C programming.

   Split out the prototypes for add/delete address into a separate header file.
