8283c726e7 If the XSDT address in the RSDP for an ACPI 2.0 machine is NULL, then fall
back to using the RSDT instead.  ACPI-CA already follows this same strategy
as a workaround for yet another instance of brain-damaged BIOS writers.

c3784d3460 In spx_output(), use M_DONTWAIT instead of M_TRYWAIT, as we hold the
ipxpcb mutex.  Contrary to the comment, even in 4.x this was unsafe,
as parallel use of the socket by another process would result in pcb
corruption if the mbuf allocation slept.

63b01ffd34 Add a sysctl, regression.sonewconn_earlytest, which when options
REGRESSION is enabled, allows user space to dictate that sonewconn()
should skip it's "skip the hard work" check to see if the listen
queue is full, and instead proceed with allocation of a socket and
trimming of the overflowed queue.  This makes it easier to test the

722542bc34 Add a new ipxpcb flag, IPXP_SPX, which is set on ipxpcb's to mark them
as belonging to SPX.  This replaces the implicit assumption that the cb
pointer for non-SPX pcb's will be NULL.  This isn't required in TCP/IP
as different pcb lists are maintained for different IP protocols; IPX
stores all pcbs on the same global ipxpcb_list.

49874f6ea3 MFP4: Support for profiling dynamically loaded objects.
Kernel changes:

  Inform hwpmc of executable objects brought into the system by
  kldload() and mmap(), and of their removal by kldunload() and
  munmap().  A helper function linker_hwpmc_list_objects() has been
  added to "sys/kern/kern_linker.c" and is used by hwpmc to retrieve
  the list of currently loaded kernel modules.

  The unused `MAPPINGCHANGE' event has been deprecated in favour
  of separate `MAP_IN' and `MAP_OUT' events; this change reduces
  space wastage in the log.

  Bump the hwpmc's ABI version to "2.0.00".  Teach hwpmc(4) to
  handle the map change callbacks.

  Change the default per-cpu sample buffer size to hold
  32 samples (up from 16).

  Increment __FreeBSD_version.

libpmc(3) changes:

  Update libpmc(3) to deal with the new events in the log file; bring
  the pmclog(3) manual page in sync with the code.

pmcstat(8) changes:

  Introduce new options to pmcstat(8): "-r" (root fs path), "-M"
  (mapfile name), "-q"/"-v" (verbosity control).  Option "-k" now
  takes a kernel directory as its argument but will also work with
  the older invocation syntax.

  Rework string handling in pmcstat(8) to use an opaque type for
  interned strings.  Clean up ELF parsing code and add support for
  tracking dynamic object mappings reported by a v2.0.00 hwpmc(4).

  Report statistics at the end of a log conversion run depending
  on the requested verbosity level.

6882aa2c03 Define two new inpcb flags in the inp_vflag field, which for whatever
reason, seems to be where new flags are getting defined:

INP_DROPPED - The protocol has terminated this connection and the socket
              is not reusable: when the socket code enters the protocol,
              an error is immediately returned.  This will substitute for
              NULLing the so_pcb socket field, helping to implement the
              invariant that all valid sockets have valid pcb's in TCP.

INP_SOCKREF - The protocol has become the owner of the socket reference,
              and will need to free it when freeing the pcb, which will
              be used when a TCP socket is closed but still has queued
              data.

a529c6a2dc Correct bad format args. Interesting- the lines that generated
the error on sparc64 hadn't changed since the last checkin, pass
LINT on other platforms and mpt doesn't work on sparc64 anyway
and the tinderbox build didn't work for me in a cross build case
on my main build machine (which runs RELENG_6). Sigh. Still
need to try harder.

818812244b Rework IPX/SPX socket and pcb reference model:
- Introduce invariant that all IPX/SPX sockets will have valid so_pcb
  pointers to ipxpcb structures, and that for SPX, the control block
  pointer will always be valid.  Don't attempt to free the socket or
  pcb at various odd points, such as disconnect.

- Add a new ipxpcb flag, IPXP_DROPPED, which will be set in place of
  freeing PCB's so that this invariant can be maintained.  This flag
  is now checked instead of a NULL check in various socket protocol
  calls.

- Introduce many assertions that this invariant holds.

- Various pieces of code, such as the SPX timer code, no longer needs
  to jump through hoops in case it frees a PCB while running.

- Break out ipx_pcbfree() from ipx_pcbdetach().  Likewise
  spx_pcbdetach().

- Comment on some SMP-related limitations to the SPX code.

- Update copyrights.

c87e3f833c Some fairly major changes to this driver.
A) Fibre Channel Target Mode support mostly works
(SAS/SPI won't be too far behind). I'd say that
this probably works just about as well as isp(4)
does right now. Still, it and isp(4) and the whole
target mode stack need a bit of tightening.

B) The startup sequence has been changed so that
after all attaches are done, a set of enable functions
are called. The idea here is that the attaches do
whatever needs to be done *prior* to a port being
enabled and the enables do what need to be done for
enabling stuff for a port after it's been enabled.

This means that we also have events handled by their
proper handlers as we start up.

C) Conditional code that means that this driver goes
back all the way to RELENG_4 in terms of support.

D) Quite a lot of little nitty bug fixes- some discovered
by doing RELENG_4 support. We've been living under Giant
*waaaayyyyy* too long and it's made some of us (me) sloppy.

E) Some shutdown hook stuff that makes sure we don't blow
up during a reboot (like by the arrival of a new command
from an initiator).

There's been some testing and LINT checking, but not as
complete as would be liked. Regression testing with Fusion
RAID instances has not been possible. Caveat Emptor.

1ab7d4c93d For each of the voltages that a card might support, make sure that the
socket also supports the voltage.  Some XV cards have appeared on the
scene (or cards that report they support XV), and in older machines
that have sockets that do not support XV, we were bogusly trying to
power them at XV rather than at 3.3V.  Now, power up the card at the
lowest voltage supported by both the card and the socket.
