1) sun4{u,v}_build_msi() have improper return value handling.

   We should always return negative error codes, instead of
   using the magic value "0" which could in fact be a valid
   MSI number.

2) sun4{u,v}_build_msi() should return -ENOMEM instead of
   calling prom_prom() halt with kzalloc() of the interrupt
   data fails.

3) We 'remembered' the MSI number using a singleton in the
   struct device archdata area, this doesn't work for MSI-X
   which can cause multiple MSIs assosciated with one device.

   Delete that archdata member, and instead store the MSI
   number in the IRQ chip data area.

When CONFIG_NET_CLS_ACT is enabled, tc_classify() is called twice in
prio_classify(). This causes "interesting" behaviour: with the setup
below, packets are duplicated, sent twice to ifb0, and then loop in and
out of ifb0.

The patch uses the previously calculated return value in the switch,
which is probably what Patrick had in mind in commit
bdba91ec -- maybe Patrick can
double-check this?

-- example setup --
ifconfig ifb0 up
tc qdisc add dev ifb0 root netem delay 2s
tc qdisc add dev $ETH root handle 1: prio

Bridge code calls ethtool to get speed. The conversion to using
only ethtool_ops broke the case of devices without ethtool_ops.
This is a new regression in 2.6.23.

Rearranged the switch to a logical order, and use gcc initializer.

Ps: speed should have been part of the network device structure from
    the start rather than burying it in ethtool.

This patch fixes some packet leakage in bridge.  The bridging code was
allowing forward table entries to be generated even if a device was
being blocked. The fix is to not add forwarding database entries
unless the port is active.

The bug arose as part of the conversion to processing STP frames
through normal receive path (in 2.6.17).

Alexey Dobriyan reports that maxcpus=1 is still broken in 2.6.23-rc4:
if CONFIG_HOTPLUG_CPU is not set, x86_64 bootup oopses in show_stat() -
for_each_possible_cpu accesses a per-cpu area which was never set up.

Alexey identified commit 61ec7567
(ACPI: boot correctly with "nosmp" or "maxcpus=0") as the origin;
but it's not really to blame, just exposes a bug in 2.6.23-rc1's commit
8b3b2955 (Especially when !CONFIG_HOTPLUG_CPU,
avoid needlessy allocating resources for CPUs that can never become available).

rc1's test for max_cpus < 2 in start_kernel() wasn't working because
max_cpus was still NR_CPUS at that point: until rc4 moved the maxcpus
parsing earlier.  Now it sets cpu_possible_map to 1 before allocating
all possible per-cpu areas; then smp_init() expands cpu_possible_map
to cpu_present_map (0xf in my case) later on.

rc1's commit has good intentions, but expects cpu_present_map to be
limited by maxcpus, which is only the case on i386.  cpus_and(possible,
possible,present) might be good, but needs an audit of cpu_present_map
uses - there may well be assumptions that any cpu present is possible.

So stay safe for now and just revert those #ifndef CONFIG_HOTPLUG_CPU
optimizations in rc1's commit.

PROTOCOL VIOLATION error cause in ABORT is bad encode when make abort
chunk. When SCTP encode ABORT chunk with PROTOCOL VIOLATION error cause,
it just add the error messages to PROTOCOL VIOLATION error cause, the
rest four bytes(struct sctp_paramhdr) is just add to the chunk, not
change the length of error cause. This cause the ABORT chunk to be a bad
format. The chunk is like this:

ABORT chunk
  Chunk type: ABORT (6)
  Chunk flags: 0x00
  Chunk length: 72 (*1)
  Protocol violation cause
    Cause code: Protocol violation (0x000d)
    Cause length: 62 (*2)

This fixes a major bug which was happening when a SPU thread advances
its execution right after being restored to a SPU.  A potentially

So, spu_run_init, in this case, was either not doing anything relevant,
or breaking the execution of the SPU thread.

When a process writes into the inbound spu mailbox (wbox) while the
