4b87c653f9 Properly wither the geom container on detach. This will allow one to
then later reload fdc and not have duplicate fd devices in dev.

b646893f0f - Eliminate the acquisition and release of the bqlock in bremfree() by
setting the B_REMFREE flag in the buf.  This is done to prevent lock order
   reversals with code that must call bremfree() with a local lock held.
   This also reduces overhead by removing two lock operations per buf for
   fsync() and similar.
 - Check for the B_REMFREE flag in brelse() and bqrelse() after the bqlock
   has been acquired so that we may remove ourself from the free-list.
 - Provide a bremfreef() function to immediately remove a buf from a
   free-list for use only by NFS.  This is done because the nfsclient code
   overloads the b_freelist queue for its own async. io queue.
 - Simplify the numfreebuffers accounting by removing a switch statement
   that executed the same code in every possible case.
 - getnewbuf() can encounter locked bufs on free-lists once Giant is removed.
   Remove a panic associated with this condition and delay asserts that
   inspect the buf until after it is locked.

This same bug was fixed in the 4.x stream a few years ago, but the fix

This fix is slightly different than in -stable:

 o Use offsetof() instead of a hard coded constant so as the make

f46d4a6741 Add a driver back end for MC146818 and compatible clocks based on the
respective NetBSD driver for use with the genclock interface.
It's first use will be on sparc64 but it was also tested on alpha with
a preliminary patch to switch alpha to use the genclock code together
with this driver instead of the respective code in alpha/alpha/clock.c
and the rather MD mcclock(4). Using it on i386 and amd64 won't be that
hard but some changes/extensions to improve the genclock code in general
should be done first, e.g. add locking and make it easier to access the
NVRAM usually coupled with RTCs.

8ff995cc5f o sparc64/isa/isa.c:
- The claim in the commit log of rev. 1.11 of dev/uart/uart_cpu_sparc64.c
    etc. that UARTs are the only relevant ISA devices on sparc64 turned out
    to be false. While there are sparc64 models where UARTs are the only
    devices on the ISA bus there are in fact also low-cost models where all
    devices traditionally found on the EBus are hooked up to the ISA bus.
    There are also models that use a mix between EBus and ISA devices with
    things like an AT keyboard controller and other rather interesting
    devices that we might want to support in the futute hook up to the ISA
    bus.
    In order to not need to add sparc64 specific device_identify methods to
    all of the respective ISA drivers and also not add OFW specific code to
    the common ISA code make the sparc64 ISA bus code fake up PnP devices so
    most ISA drivers probe their devices without further changes.
    Unfortunately Sun doesn't adhere to the ISA bindings defined in IEEE
    1275-1994 for the properties of most of the ISA devices which would
    allow to obtain the vendor and logical IDs from their properties. So we
    we just use a simple table which maps the name properties to PnP IDs.
    This could be done in a more sophisticated way but I courrently don't
    see the need for this. [1]
  - Add the children with fully mapped and specified resources (in the OFW
    sense) similar to what is done in the EBus code for the IRQ resources
    of the children as adjusting the resources and the resource list entries
    respectively in isa_alloc_resource() as done perviously causes trouble
    with drivers which use rman_get_start(), pass-through or allocate and
    release resources multiple times, etc.
    Adjusting the resources might be better off in a bus_activate_resource
    method but the common ISA code currently doesn't allow for an
    isa_activate_resource(). [2]
    With this change:
    - ppbus(4) and lpt(4) attach and work (modulo ECP mode, which requires
      real ISADMA code but it currently only consists of stubs on sparc64).
    - atkbdc(4) and atkbdc(4) attach, no further testing done.
    - fdc(4) itself attaches but causes a hang while attaching fd0 also
      when is DMA disabled, further work in fdc(4) is required here as e.g.
      fd0 uses the address of fd1 on sparc64 (not sure if sparc64 supports
      more than one floppy drive at all).
    All of these drivers previously caused panics in the sparc64 ISA code.
  - Minor changes, e.g. use __FBSDID, remove a dupe word in a comment and
    declare one global variable which isn't used outside of isa.c static.
o dev/uart/uart_cpu_sparc64.c and modules/uart/Makefile:
  - Remove the code for registering the UARTs on the ISA bus from the
    sparc64 uart_cpu_identify() again and rely on probing them via PnP.

I have in mind for the genclock interface):
  - Recognize the MK48T18 as well (differs from the MK48T08 only in
    packaging options and voltages).
  - Allow MD code to provide functions for reading/writing NVRAM/RTC
    locations.
    If passed NULL, the old behaviour using bus_space_{read,write}_1() is
    used. Otherwise, all access to the chip goes via the MD functions.
    This is necessary for mvmeppc boards where the mk48txx NVRAM/RTC is
    not directly addressable.
  - Cleanup MI mk48txx(4) todclock driver:
    - Prepare mk48txxvar.h and leave only register definitions in
      mk48txxreg.h.
    - Define struct mk48txx_softc as usual devices and allocate necessary
      members in it.
    - Change mk48txx_attach() to only take a device_t.
o While converting the sparc64 eeprom driver to the above changes:
  - Remove some dead code and stale comments.
  - Use the NVRAM size provided by the mk48txx driver instead of hardcoding
    it as suggested by a comment.
  - Add a comment about why it doesn't make much sense to read the hostid
    directly from the NVRAM except for displaying it when attaching.
  - Don't print the hostid if it reads all zero because it's stored
    elsewhere.

d533c6e9a5 Split the FILEDESC_LOCK in two variants.
FILEDESC_LOCK_FAST will just grab the interlocking mutex and hold
it.  This should be used for simple modifications of a field.

FILEDESC_LOCK holds a (homegrown) sleepable lock which should be used
where sleeping is required.

The homegrown lock will probably be replaced with a generic type of lock
once we have found out how that should look.

a51dae09ec Adjust the interrupt storm handling code to better handle a storm. When
a storm is detected, enter "storming" mode which throttles the interrupt
source such that the handlers are run once every clock tick.  Previously
we allowed a full set of storm_threshold interations through the handler
before going back to sleep.  Also, this currently will intentionally exit
storming mode once a second to see if the storm has passed.

drivers don't appear to do anything i386 specific, so move them to
dev/acpi_support.  Move config lines to files so that those

a0c88fb1d9 Remove the BR tag. When the machine doesn't have the DIG64 HCDP
table with console settings, we now only need to know at which
address the UART lives. Leaving the baudrate unspecified results

out of the box.

54e2bcc7ad Add UART_IOCTL_BAUD to allow us to query the hardware about the

baudrate of the sysdev (as represented by a 0 value). When the
ioctl() fails, e.g. when the backend hasn't implemented it or the
hardware doesn't provide the means to determine its current baudrate
setting, we invalidate the baudrate setting by setting it to -1.
None of the backends currently implement the new ioctl().

ecf4dc2505 Make sure the baudrate specified with the BR tag is somewhat sane.
A baudrate we consider insane is silently replaced with 0. When the
baudrate is 0, we will not try to program the hardware. Instead we
leave the communication speed unaltered, maximizing the chance to
have a working console. Obviously this means we allow specifying a
0 baudrate for exactly that purpose.

1eef0330d9 Further refine the if_em vlan fix in if_em.c:1.53:
- Because em_encap() can now fail in a way that leaves us without an
  mbuf chain, potentially set *m_headp to NULL if that happens, so that
  the caller can do the right thing.  This case can occur when we try
  to prepend the vlan header mbuf but can't allocate additional memory.

- Modify the caller of em_encap() to detect a NULL m_head and not try
  to queue the mbuf if that happens.

- When em_encap() fails, make sure to call bus_dmamap_destroy() to
  clean up.

- refactor changes introduced in rev. 1.100: do not prepend a new tag

A small note for all hacking in this area:
when divert socket is not a real userland, but ng_ksocket(4), we receive
_the same_ mbufs, that we transmitted to socket. These mbufs have rcvif,
the tags we've put on them. And we should treat them correctly.

with IFA_ROUTE set, we try to find a "fallback" address and hand over the
route if possible.
I plan to MFC this in 4 weeks, hence I keep the - now obsolete - argument to
in_ifscrub as it must be considered KAPI as it is not static in in.c. I will
clean this after the MFC.

921d05b90d Second of several commits to allow kernel System V IPC data structures
to be modified and extended without breaking the user space ABI:

Use _kernel variants on _ds structures for System V sempahores, message
queues, and shared memory.  When interfacing with userspace, export
only the _ds subsets of the _kernel data structures.  A lot of search
and replace.

Define the message structure in the _KERNEL portion of msg.h so that it
can be used by other kernel consumers, but not exposed to user space.

to be modified and extended without breaking the user space ABI:

Define _kernel wrapper data structures for the user-exposed data
structures that current server as the internal data structures for

- struct msqid_kernel wraps struct msqid_ds.
- struct semid_kernel wraps truct semid_ds.
- struct shmid_kernel wraps struct shmid_ds.
- Don't expose extern definition 'shmsegs' outside of sysv_shm.c.

16142b2b03 Correct a bug in the if_em driver relating to the use of vlans with
promiscuous mode introduced in 1.45, which programs the em card not
to strip or prepend tags when in promiscuous mode without also
modifying behavior to manually prepend a vlan header in the event
that the card isn't doing it on transmit.  Due to a feature of card
operation, if the global VLAN prepend/strip register isn't set,
setting the VLAN tag flag on individual packet descriptors will
cause the packet to be transmitted using ISL encapsulation rather
than 802.1Q VLAN encapsulation.

This fix causes em_encap() to prepend the header by tracking whether
the card is configured to temporarily disable prepending/stripping
due to promiscuous mode.  As a result, entering promiscuous mode on
the parent em interface no longer causes vlans to appear to "wedge"
or transmit ISL-encapsulated frames, which typically will not be
configured/spoken by the other endpoints on the VLAN trunk.  This
bug may also exist in other drivers, and the additional vlan
encapsulation logic should be abstracted and centralized in
if_vlan.c if so.

RELENG_5_3 candidate.

85b8134e51 Back out my recent changes for timeout races, as there have been
reports of problems. The bug is probably that there are cases where
`xfer->timeout && !sc->sc_bus.use_polling' is not a suitable test
for an active timeout callout, so an explicit flag will be necessary.
Apologies for the breakage.

57621b8b35 - Place the gcc memory barrier hint in the right place in the 80386 version
of atomic_store_rel().
- Use the 80386 versions of atomic_load_acq() and atomic_store_rel() that
  do not use serializing instructions on all UP kernels since a UP machine
  does need to synchronize with other CPUs.  This trims lots of cycles from
  spin locks on UP kernels among other things.

29af382686 Correct a bug in nfsrv_create() where a call to nfsrv_access() might
be made holding the NFS server mutex.  To clean this up, introduce a
version of the function, nfsrv_access_withgiant(), that expects the
NFS server mutex to already have been dropped and Giant acquired.
Wrap nfsrv_access() around this.  This permits callers to more
efficiently check access if they're in a code block performing VFS
operations, and can be substitited for the nfsrv_access() call that
triggered this bug.
