Usbnet framework assumes USB hardware doesn't handle zero length
packets, but SMSC LAN95xx requires these to be sent for correct
operation.

This patch fixes an easily reproducible tx lockup when sending a frame
that results in exactly 512 bytes in a USB transmission (e.g. a UDP
frame with 458 data bytes, due to IP headers and our USB headers).  It
adds an extra flag to usbnet for the hardware driver to indicate that
it can handle and requires the zero length packets.

This patch should not affect other usbnet users, please also consider
for -stable.

kaweth_control() never frees the buffer that it allocates for the USB
control message.  Test case:

while :; do ifconfig eth2 down ; ifconfig eth2 up ; done

This is a tiny buffer so it is a slow leak.  If you want to speed up the
process, you can change the allocation size to e.g. 16384 bytes, and it
will consume several megabytes within a few minutes.

For non-accepted sockets on the accept queue, iucv_sock_kill()
is called twice (in iucv_sock_close() and iucv_sock_cleanup_listen()).
This typically results in a kernel oops as shown below.

Remove the duplicate call to iucv_sock_kill() and set the SOCK_ZAPPED
flag in iucv_sock_close() only.

The iucv_sock_kill() function frees a socket only if the socket is zapped
and orphaned (sk->sk_socket == NULL):
  - Non-accepted sockets are always orphaned and, thus, iucv_sock_kill()
    frees the socket twice.
  - For accepted sockets or sockets created with iucv_sock_create(),
    sk->sk_socket is initialized. This caused the first call to
    iucv_sock_kill() to return immediately. To free these sockets,
    iucv_sock_release() uses sock_orphan() before calling iucv_sock_kill().

stores the size of the interrupt buffer instead of the maximum number
of connections.

According to the QUERY IUCV function, general register 1 contains the
maximum number of connections.

If the maximum number of connections is not set properly, the following
warning is displayed:

Prior to calling IUCV functions, the DECLARE BUFFER function must have been
called for at least one CPU to receive IUCV interrupts.

With commit "iucv: establish reboot notifier" (6c005961), a check has been
introduced to avoid calling IUCV functions if the current CPU does not have
an interrupt buffer declared.
Because one interrupt buffer is sufficient, change the condition to ensure
that one interrupt buffer is available.

In addition, checking the buffer on the current CPU creates a race with
CPU up/down notifications: before checking the buffer, the IUCV function
might be interrupted by an smp_call_function() that retrieves the interrupt
buffer for the current CPU.
When the IUCV function continues, the check fails and -EIO is returned. If a
buffer is available on any other CPU, the IUCV function call must be invoked
(instead of failing with -EIO).

During suspend IUCV exploiters have to close their IUCV connections.
When restoring an image, it can be checked if all IUCV pathes had
been closed before the Linux instance was suspended. If not, an
error message is issued to indicate a problem in one of the
used programs exploiting IUCV communication.
