ddcc3ff59e o Add support for UltraSparc-IV+:
- Swap the configuration of the first and second large dTLB as with
    US-IV+ these can only hold entries of certain page sizes each, which
    we happened to chose the non-working way around.
  - Additionally ensure that the large iTLB is set up to hold 8k pages
    (currently this happens to be a NOP though).
  - Add a workaround for US-IV+ erratum #2.
  - Turn off dTLB parity error reporting as otherwise we get seemingly
    false positives when copying in the user window by simulating a
    fill trap on return to usermode. Given that these parity errors can
    be avoided by disabling multi issue mode and the problem could be
    reproduced with a second machine this appears to be a silicon bug of
    some sort.
  - Add a membar #Sync also before the stores to ASI_DCACHE_TAG. While
    at it, turn of interrupts across the whole cheetah_cache_flush() for
    simplicity instead of around every flush. This should have next to no
    impact as for cheetah-class machines we typically only need to flush
    the caches a few times during boot when recovering from peeking/poking
    non-existent PCI devices, if at all.
  - Just use KERNBASE for FLUSH as we also do elsewhere as the US-IV+
    documentation doesn't seem to mention that these CPUs also ignore the
    address like previous cheetah-class CPUs do. Again the code changing
    LSU_IC is executed seldom enough that the negligible optimization of
    using %g0 instead should have no real impact.

  With these changes FreeBSD runs stable on V890 equipped with US-IV+
  and -j128 buildworlds in a loop for days are no problem. Unfortunately,
  the performance isn't were it should be as a buildworld on a 4x1.5GHz
  US-IV+ V890 takes nearly 3h while on a V440 with (theoretically) less
  powerfull 4x1.5GHz US-IIIi it takes just over 1h. It's unclear whether
  this is related to the supposed silicon bug mentioned above or due to
  another issue. The documentation (which contains a sever bug in the
  description of the bits added to the context registers though) at least
  doesn't mention any requirements for changes in the CPU handling besides
  those implemented and the cache as well as the TLB configurations and
  handling look fine.
o Re-arrange cheetah_init() so it's easier to add support for SPARC64
  V up to VIIIfx CPUs, which only require parts of this initialization.

319efdb1cc - Add TTE and context register bits for the additional page sizes supported
by UltraSparc-IV and -IV+ as well as SPARC64 V, VI, VII and VIIIfx CPUs.
- Replace TLB_PCXR_PGSZ_MASK and TLB_SCXR_PGSZ_MASK with TLB_CXR_PGSZ_MASK
  which just is the complement of TLB_CXR_CTX_MASK instead of trying to
  assemble it from the page size bits which vary across CPUs.
- Add macros for the remainder of the SFSR bits, which are useful for at
  least debugging purposes.

cb2f0c8ce1 - Add quirk handling for Sun Fire V1280. The firmware of these machines
provides no ino-bitmap properties so forge them using the default set
  of controller interrupts and let schizo_setup_intr() take care of the
  children, hoping for non-fancy routing.
- Add quirk handling for Sun Fire V890. When booting these machines from
  disk a Schizo comes up with PCI error residing which triggers as soon
  as we register schizo_pci_bus() even when clearing it from all involved
  registers (it's no longer indicated once we're in schizo_pci_bus()
  though). Thus make PCI bus errors non-fatal until we actually touch the
  bus. With this change schizo_pci_bus() typically triggers once during
  attach in this case. Obviously this approach isn't exactly race free
  but it's about the best we can do about this problem as we're not
  guaranteed that the interrupt will actually trigger on V890 either, as
  it certainly doesn't when for example netbooting them.

3804454ac0 Revamp the interrupt code based on the previous commit:
o   Introduce XIV, eXternal Interrupt Vector, to differentiate from
    the interrupts vectors that are offsets in the IVT (Interrupt
    Vector Table). There's a vector for external interrupts, which
    are based on the XIVs.

o   Keep track of allocated and reserved XIVs so that we can assign
    XIVs without hardcoding anything. When XIVs are allocated, an
    interrupt handler and a class is specified for the XIV. Classes
    are:
    1.  architecture-defined: XIV 15 is returned when no external
	interrupt are pending,
    2.  platform-defined: SAL reports which XIV is used to wakeup
	an AP (typically 0xFF, but it's 0x12 for the Altix 350).
    3.  inter-processor interrupts: allocated for SMP support and
	non-redirectable.
    4.  device interrupts (i.e. IRQs): allocated when devices are
	discovered and are redirectable.

o   Rewrite the central interrupt handler to call the per-XIV
    interrupt handler and rename it to ia64_handle_intr(). Move
    the per-XIV handler implementation to the file where we have
    the XIV allocation/reservation. Clock interrupt handling is
    moved to clock.c. IPI handling is moved to mp_machdep.c.

o   Drop support for the Intel 8259A because it was broken. When
    XIV 0 is received, the CPU should initiate an INTA cycle to
    obtain the interrupt vector of the 8259-based interrupt. In
    these cases the interrupt controller we should be talking to
    WRT to masking on signalling EOI is the 8259 and not the I/O
    SAPIC. This requires adriver for the Intel 8259A which isn't
    available for ia64. Thus stop pretending to support ExtINTs
    and instead panic() so that if we come across hardware that
    has an Intel 8259A, so have something real to work with.

o   With XIVs for IPIs dynamically allocatedi and also based on
    priority, define the IPI_* symbols as variables rather than
    constants. The variable holds the XIV allocated for the IPI.

o   IPI_STOP_HARD delivers a NMI if possible. Otherwise the XIV
    assigned to IPI_STOP is delivered.

Luigi Rizzo
f9f7bde3bc + implement (two lines) the kernel side of 'lookup dscp N' to use the
dscp as a search key in table lookups;

+ (re)implement a sysctl variable to control the expire frequency of
  pipes and queues when they become empty;

+ add 'queue number' as optional part of the flow_id. This can be
  enabled with the command

        queue X config mask queue ...

  and makes it possible to support priority-based schedulers, where
  packets should be grouped according to the priority and not some
  fields in the 5-tuple.
  This is implemented as follows:
  - redefine a field in the ipfw_flow_id (in sys/netinet/ip_fw.h) but
    without changing the size or shape of the structure, so there are
    no ABI changes. On passing, also document how other fields are
    used, and remove some useless assignments in ip_fw2.c

  - implement small changes in the userland code to set/read the field;

  - revise the functions in ip_dummynet.c to manipulate masks so they
    also handle the additional field;

There are no ABI changes in this commit.
