a1f76946d5 Merge from CheriBSD:
commit d0c7d235c09fc65dbdb278e7016a96f79c6a49cc
    Make the Altera JTAG UART device driver slightly more forgiving of
    the foibles of a sub-par hrdware interface by increasing the timeout
    for spotting JTAG polling from one to two seconds.

commit 19ed45a18832560dab967c179d83b71081c3a220
    Update comment.

commit 8edfe803f033cc8e33229f99894c2b7496a44d5f
    Add a comment about a device-driver race condition that could cause the BERI
    pipeline to wedge awaiting JTAG in the event that both the low-level console
    and the tty layer decide to write to the JTAG FIFO just before JTAG is
    disconnected.  Resolving this race is a bit tricky as it looks like there
    isn't a way to 'give the character back' to the tty layer when we discover
    the race.  The easy fix is to drop the character, which we don't yet do, but
    perhaps should as that is a better outcome than wedging the pipeline.

commit 2ea26cf579c9defcf31e413e7c9b0fbc159237fc
    Add a comment about an inherent race with hardware in the Altera JTAG
    UART's low-level console code.

85c9dd9d89 Prevent overflow issues in timeout processing
Previously, any timeout value for which (timeout * hz) will overflow the
signed integer, will give weird results, since callout(9) routines will
convert negative values of ticks to '1'. For unsigned integer overflow we
will get sufficiently smaller timeout values than expected.

Switch from callout_reset, which requires conversion to int based ticks
to callout_reset_sbt to avoid this.

Also correct isci to correctly resolve ccb timeout.

This was based on the original work done by Eygene Ryabinkin
<rea@freebsd.org> back in 5 Aug 2011 which used a macro to help avoid
the overlow.

180e57e5c7 Improve support for XSAVE with debuggers.
- Dump an NT_X86_XSTATE note if XSAVE is in use. This note is designed
  to match what Linux does in that 1) it dumps the entire XSAVE area
  including the fxsave state, and 2) it stashes a copy of the current
  xsave mask in the unused padding between the fxsave state and the
  xstate header at the same location used by Linux.
- Teach readelf() to recognize NT_X86_XSTATE notes.
- Change PT_GET/SETXSTATE to take the entire XSAVE state instead of
  only the extra portion. This avoids having to always make two
  ptrace() calls to get or set the full XSAVE state.
- Add a PT_GET_XSTATE_INFO which returns the length of the current
  XSTATE save area (so the size of the buffer needed for PT_GETXSTATE)
  and the current XSAVE mask (%xcr0).

This change saves/restores the callee-saved MIPS floating point
registers as documented by the o32/n32/n64 spec ("MIPSpro N32
ABI Handbook", Table 2-1) for the _setjmp(3), _longjmp(3),
setjmp(3) and longjmp(3) C library functions.  This is only
included when the C library is built with hardware floating point
support (or when "SOFTFLOAT" is not defined).

23b30f5600 Partially reconstruct Active/Standby clusting.
In this mode one head is in Active state, supporting all commands, while
another is in Standby state, supporting only minimal LUN discovery subset.

It is still incomplete since Standby state requires reservation support,
which is impossible to do right without having interlink between heads.
But it allows to run some basic experiments.

a92cf726f8 Lock the scsi_low code and the drivers which use it along with other
related cleanups:
- Require each driver to initalize a mutex in the scsi_low_softc that
  is shared with the scsi_low code.  This mutex is used for CAM SIMs,
  timers, and interrupt handlers.
- Replace the osdep function switch with direct calls to the relevant
  CAM functions and direct manipulation of timers via callout(9).
- Collapse the CAM-specific scsi_low_osdep_interface substructure
  directly into scsi_low_softc.
- Use bus_*() instead of bus_space_*().
- Return BUS_PROBE_DEFAULT from probe routines instead of 0.
- No need to zero softcs.
- Pass 0ul and ~0ul instead of 0 and ~0 to bus_alloc_resource().
- Spell "dettach" as "detach".
- Remove unused 'dvname' variables.
- De-spl().
