ac2bbfc8cf o Make sure to clear f->f_devdata if d_dev->dv_open() fails. It
would otherwise cause devclose() to free() the memory again.
o  Refactor devopen() so that it's more readable.

65deb9d947 - In sunkbd_probe_keyboard() don't bother to determine the keyboard layout
as we have no use for that info. Instead let this function return the
  keyboard ID and verify at its invocation in sunkbd_configure() that we're
  talking to a Sun type 4/5/6 keyboard, i.e. a keyboard supported by this
  driver.
- Add an option SUNKBD_EMULATE_ATKBD whose code is based on the respective
  code in ukbd(4) and like UKBD_EMULATE_ATSCANCODE causes this driver to
  emit AT keyboard/KB_101 compatible scan codes in K_RAW mode as assumed by
  kbdmux(4). Unlike UKBD_EMULATE_ATSCANCODE, SUNKBD_EMULATE_ATKBD also
  triggers the use of AT keyboard maps and thus allows to use the map files
  in share/syscons/keymaps with this driver at the cost of an additional
  translation (in ukbd(4) this just is the way of operation).
- Implement an option SUNKBD_DFLT_KEYMAP, which like the equivalent options
  of the other keyboard drivers allows to specify the default in-kernel
  keyboard map. For obvious reasons this made to only work when also using
  SUNKBD_EMULATE_ATKBD.
- Implement sunkbd_check(), sunkbd_check_char() and sunkbd_clear_state(),
  which are also required for interoperability with kbdmux(4).
- Implement K_CODE mode and FreeBSD keypad compose.
- As a minor hack define KBD_DFLT_KEYMAP also in the !SUNKBD_EMULATE_ATKBD
  case so we can obtain fkey_tab from <dev/kbd/kbdtables.h> rather than
  having to duplicate it and #ifdef some more code.
- Don't use the TX-buffer for writing the two command bytes for setting the
  keyboard LEDs as this consequently requires a hardware FIFO that is at
  least two bytes in depth, which the NMOS-variant of the Zilog SCCs doesn't
  have. Thus use an inlined version of uart_putc() to consecutively write
  the command bytes (a cleaner approach would be to do this via the soft
  interrupt handler but that variant wouldn't work while in ddb(4)). [1]
- Fix some minor style(9) bugs.

power failure or system crash.

3fab76690c Bring in support for the Rapid Spanning Tree Protocol (802.1w).
RSTP provides faster spanning tree convergence, the protocol will exchange
information with neighboring switches to quickly transition to forwarding
without creating loops. The code will default to RSTP mode but will downgrade
any port connected to a legacy STP network so is fully backward compatible.

3d068827c2 Add a cnputs() function to write a string to the console with
a lock to prevent interspersed strings written from different CPUs
at the same time.

To avoid putting a buffer on the stack or having to malloc one,
space is incorporated in the per-cpu structure. The buffer
size if 128 bytes; chosen because it's the next power of 2 size
up from 80 characters.

String writes to the console are buffered up the end of the line
or until the buffer fills. Then the buffer is flushed to all
console devices.

Existing low level console output via cnputc() is unaffected by
this change. ithread calls to log() are also unaffected to avoid
blocking those threads.

A minor change to the behaviour in a panic situation is that
console output will still be buffered, but won't be written to
a tty as before. This should prevent interspersed panic output
as a number of CPUs panic before we end up single threaded
running ddb.

- Add fs_unrefs field to the super block structure which holds

- When file or a directory is orphaned (last reference is removed, but
  object is still open), increase fs_unrefs and cg_unrefs fields,
  which is a hint for fsck in which cylinder groups looks for such
  (orphaned) objects.
- When file is last closed, decrease {fs,cg}_unrefs fields.

fa9ed86506 The first of 3 major steps to move the CAM layer forward to using
the CAM_NEW_TRAN_CODE that has been in the tree for some years now.

This first step consists solely of adding to or correcting
CAM_NEW_TRAN_CODE pieces in the kernel source tree such
that a both a GENERIC (at least on i386) and a LINT build
with CAM_NEW_TRAN_CODE as an option will compile correctly
and run (at least with some the h/w I have).

After a short settle time, the other pieces (making
CAM_NEW_TRAN_CODE the default and updating libcam
and camcontrol) will be brought in.

This will be an incompatible change in that the size of structures
related to XPT_PATH_INQ and XPT_{GET,SET}_TRAN_SETTINGS change
in both size and content. However, basic system operation and
basic system utilities work well enough with this change.

b0a2d4b8a9 More fully support 64-bit bars. Prior to this commit, we supported
only those bars that had addresses assigned by the BIOS and where the
bridges were properly programmed.  Now even unprogrammed ones work.
This was needed for sun4v.  We still only implement up to 2GB memory
ranges, even for 64-bit bars.  PCI standards at least through 2.2 say
that this is the max (or 1GB is, I only know it is < 32bits).

o Always define pci_addr_t as uint64_t.  A pci address is always 64-bits,
  but some hosts can't address all of them.
o Preserve the upper half of the 64-bit word during resource probing.
o Test to make sure that 64-bit values can fit in a u_long (true on some
  platforms, but not others).  Don't use those that can't.
o minor pedantry about data sizes.
o Better bridge resource reporting in bootverbose case.
o Minor formatting changes to cope with different data types on different
  platforms.
