Hi,

Reinhard Max also pointed out that the error should EAFNOSUPPORT according
to POSIX.

The Linux manpages have it as EINVAL, some other OSes (Minix, HPUX, perhaps BSD) use
EAFNOSUPPORT. Windows uses WSAEFAULT according to MSDN.

Other protocols error values in their af bind() methods in current mainline git as far
as a brief look shows:
	EAFNOSUPPORT: atm, appletalk, l2tp, llc, phonet, rxrpc
	EINVAL: ax25, bluetooth, decnet, econet, ieee802154, iucv, netlink, netrom, packet, rds, rose, unix, x25,
	No check?: can/raw, ipv6/raw, irda, l2tp/l2tp_ip

Ciao, Marcus

IPV6, unlike IPV4, doesn't have a routing cache.

Routing table entries, as well as clones made in response
to route lookup requests, all live in the same table.  And
all of these things are together collected in the destination
cache table for ipv6.

This means that routing table entries count against the garbage
collection limits, even though such entries cannot ever be reclaimed
and are added explicitly by the administrator (rather than being
created in response to lookups).

Therefore it makes no sense to count ipv6 routing table entries
against the GC limits.

Add a DST_NOCOUNT destination cache entry flag, and skip the counting
if it is set.  Use this flag bit in ipv6 when adding routing table
entries.

The message hints that disc_data_lock is aquired with softirqs disabled,
but does not itself disable softirqs, which can in rare circumstances
lead to a deadlock. 
The same problem is present in the 6pack driver, this patch fixes both
by using write_lock_bh instead of write_lock.

It's not so much an error as a warning about normal Marvell crazines.
So don't use KERN_ERR that ends up spamming the console even in quiet
mode, it's not _that_ critical.

Explained by Jeff:

 "Long explanation, it's a mess:

  Marvell took standard AHCI, and bastardized it to include a weird mode
  whereby PATA devices appear inside the AHCI DMA and interrupt
  infrastructure you're familiar with.

  So, PATA devices appear via pata_marvell driver, using basic legacy
  IDE programming interface.  But SATA devices, which might also be
  attached to this chip, either work in under-performing mode or
  simply don't work at all (e.g.  newer 6 Gbps devices or port
  multiplier attachments, NCQ, ...)

  On the other hand, 'ahci' driver loads and works with the chip's
  attached SATA devices quite beautifully, but is completely unable to
  drive any attached PATA devices, due to the Marvell-specific
  PATA-under-AHCI interface.

  The "masking port_map 0x7 -> 0x3" message is the ahci driver "hiding"
  the PATA port(s) from itself, making sure it will only drive the SATA
  ports it knows how to drive."

This module and a bunch of dependancies are getting loaded on several
of laptops I have (probably picking up the mobile broadband device),
that have nothing to do with zaurus. Matching by class without
any vendor/device pair isn't the right thing to do here, as it
will prevent any other driver from correctly binding to it.
(Or in the absense of a driver, will just waste time & memory by
 unnecessarily loading modules)

We want people to just use the list now rather than hitting up people
who are no longer responsible for it.

activate them by default, change to "default y".

Function rionet_remove initializes local variable 'ndev' to NULL
and do nothing changes before the call to unregister_netdev(ndev),
this could cause a NULL pointer dereference.

They are 64K and result in order-4 allocations, even with SLUB.

Therefore, just like we always have for the deflate buffers, use
vmalloc.
