MFC: psycho.c 1.61; psychoreg.h 1.12
o Changes to psycho_attach(): [1]
- Clear the PCI AFSR and status error bits as previous errors still
might be indicated.
- Set up the PCI control and diagnostic registers according to the
capabilities, workarounds, etc of/for specific revisions of the
supported bridges. This includes no longer setting Hummingbird-/
Sabre-specific bits in the PCI control register but preserving
what the firmware has initialized them to like OpenSolaris does.
Previously we were setting these bits according to the example in
the Sabre documentation, which I doubt is appropriate for all
Sabre based designs and especially not for Hummingbirds. This
also includes not enabling bus parking unless the firmware tells
us to.
- Set the PCI latency timer register as this isn't always done by
the firmware.
o Remove a redundant argument from psycho_set_intr() and in this
function check the return value of bus_setup_intr(). [2]
o Let psycho_setup_intr() return ENOMEM instead of 0 when it can't
allocate memory for the interrupt wrapper stub and EINVAL instead
of 0 if it can't find the interrupt vector in the interrupt map.
o Add a workaround for a bug of the Sabre-APB-combination where it
doesn't drain DMA write data for devices behind additional PCI-PCI
bridges underneath the APB PCI-PCI bridge. This workaround (do
things necessary in order to achieve a manual drain when coherency
is required) is currently implemented in psycho_setup_intr() and
psycho_intr_stub() due to lack of a real BUS_GET_DMA_TAG() and
psycho(4)-specific bus_dma_tag_create() and bus_dmamap_sync()
methods, respectively, in RELENG_6 and therefore is only applied
for interrupt handlers but not for polling(4) callbacks. [3]
o Fix some minor style issues.

MFC: Various fixes to cpu_reset_real()
- Try to use the reset control register (I/O port 0xcf9) and the fast a20
and init register (I/O port 0x92) if the keyboard reset fails.
- Fix the triple fault to actually work when PGE is enabled.
Modified release notes:
- ncurses was updated from version 5.2-20020615
- MSI-X supported as well, remove ref to pci(4) manpage, which is
different from the kernel's PCI code
- Patch for AD1981B codec to enable (automuting) headphone jack sense.
- Enable tone / 3D controls for YAMAHA YMF743, 753 and 752 (partially) [1]
- AC97 quirk / patch cleanups. Most quirks doesn't work in general sense
and should only be applied on certain specific card / vendor, hence the
addition of ac97_getsubvendor(). [2]
- Fix low volume issue on several MSI laptops through ALC655 quirk. [2]
In account management, verify whether the account has been locked
with `pw lock', so that it's impossible to log into a locked account
using an alternative authentication mechanism, such as an ssh key.
This change affects only accounts locked with pw(8), i.e., having a
`*LOCKED*' prefix in their password hash field, so people still can
use a different pattern to disable password authentication only.
Mention all account management criteria in the manpage.
MFC bridgestp.c r1.35-36, bridgestp.h r1.13, if_bridge.c r1.94-95
- Change the passing of callbacks to a struct in case this needs to be
extended in the future.
- Properly move the setting of bstp_linkstate_p to the bridgestp module.
MFC if_re.c, rev. 1.89 if_rlreg.h, rev 1.65 to RELENG_6.
Don't reinitialize the hardware if only PROMISC flag was changed.
Previously whenever PROMISC mode turned on/off link renegotiation
occurs and it could resulted in network unavailability for serveral
seconds.(Depending on switch STP settings it could last several tens
seconds.)
MFC: Don't hold the vnode interlock across a tsleep() in nfs_flush().
This was actually contained in the MPSAFE NFS client changes which is not
all being MFC'd, however, this fixes a bug in the previous fix to
nfs_flush().
MFC:
- In nfs_flush(), clear the NMODIFIED bit only if there are no dirty
buffers *and* there are no buffers queued up for writing.
- Keep track of the number of in-progress async direct IO writes in the
nfsnode. Make fsync/close wait until all of these drain. Add a check to
nfs_getpage() and nfs_putpage().
MFC:
Invalidate all TLBs and page structure caches that may reference a page
for page walk acceleration before releasing it to the free list.
This is required for CPUs implementing page structure caches as described
in the Intel application note:
"TLBs, Paging-Structure Caches, and Their Invalidation"
(Document Number: 317080-001)
Add a new sysctl net.inet.ip6.rthdr0_allowed, which is default off,
to disable the processing of Route Header Type 0 options in IPv6.
This is not really an MFC because currently in HEAD the processing
of these options is disabled unilateraly pending discussion at the IETF
on the future of such headers.
MFC rev. 1.208:
When LK_NOWAIT is passed as argument to process_worklist_item(), this
does not prevent handle_workitem_remove() from recursing into a blocking
version. Add the dirrem to worklist instead of processing it now if this
is the case.
MFC rev. 1.209:
Recalculate the NEWBLOCK flag for pagedep structure after the softdep
lock is dropped, since pagedep may be already processed and deallocated.
MFC: Don't go to a whole lot of extra work to handle the race where the
new file descriptor is closed out from under us in kern_open(). This race
is already handled and the file will be closed when kern_open() does an
fdrop just before returning.
In addition, by handling the race early, this opens the code up to an
obscure bug where opening a devfs file could replace f_ops in the file
object so that fdrop() will try to close the vnode, but f_vnode never gets
set, so the vnode close routine panics due to the NULL f_vnode.
Shorten text string for ip_fw2 dynamic rules zone by removing the word
"zone", which is generally not present in zone names. This reduces the
incidence of line-wrapping in "vmstat -z " using 80-column displays.
Include a note in the sendmail 8.14.1 release note regarding the libmilter
update. Unfortunately, this problem (the need to recompile filters) was
found after the MFC. The release engineering team has asked for this
instead of doing a full backout of sendmail 8.14 in the RELENG_[456]
branches.
Don't forget to close the range if we branched over its end
and had no chance to match it by the 2nd address precisely.
Otherwise the unclosed range would bogusly extend to the end
of stream.
Add missing newline to correct failure of the regression test.
According to IEEE Std 1003.1, 2004 "Whenever the pattern space is
written to standard output or a named file, sed shall immediately
follow it with a <newline>."
Implement pmap_enter_object(). Note that this change is not an MFC
because support for the Alpha was removed from the HEAD of CVS just
before the introduction of pmap_enter_object(). I am adding
pmap_enter_object() to the Alpha because it allows for an efficient
solution to a race condition affecting pmap_enter_quick(). (See
sys/amd64/amd64/pmap.c revision 1.557.)
MFC if_msk.c, rev. 1.13 to RELENG_6
Add work around for hardware Tx checksum offload bug in Yukon II.
Yukon II generated corrupted TCP checksum for short TCP packets
that's less than 60 bytes in size(e.g. window probe packet, pure ACK
packet etc). Padding the frame with zeros to make the frame minimum
ethernet frame size didn't work at all. Instead of dropping Tx
checksum offload support we calculate TCP checksum with S/W method
when we encounter short TCP frames.
Fortunately it seems that short UDP datagrams appear to be handled
correctly by Yukon II.
While I'm here simplify ethernet/VLAN header size calculation logic.
[1] Record rc.d/nfslocking dependency on rc.d/rpcbind
[2]Add rpc_statd_flags and rpc_lockd_flags options to allow
options to be passed to rpc.statd and rpc.lockd
MFC rev. 1.16 and rev. 1.17
1.16: compile under WARNS=6
1.17: Make rpc.statd INET* indipendent by converting
sockaddr_in structures to sockaddr ones and using
svc_getrpccaller instead of svc_getcaller.
A similar patch was committed to rpc.lockd back in 2002 . [1]

MFC rev. 1.16:
Fix setting of serial port speed. A junk value was passed in AX when
bioscom is called to set up serial port parameters because COMSPEED
was treated as an address instead of an immediate value, causing
serial port parameters to never be set.
