Fixes bugzilla #8895

If a super-tree leaf has 'rt' assigned to it and we
get an error from fib6_add_rt2node(), we'll leave
a reference to 'rt' in pn->leaf and then do an
unconditional dst_free().

We should prune such references.

dev_get_by_index() may return NULL if nothing is found. In 
net/netlabel/netlabel_unlabeled.c::netlbl_unlabel_staticlist_gen() the 
function is called, but the return value is never checked. If it returns 
NULL then we'll deref a NULL pointer on the very next line.
I checked the callers, and I don't think this can actually happen today, 
but code changes over time and in the future it might happen and it does 
no harm to be defensive and check for the failure, so that if/when it 
happens we'll fail gracefully instead of crashing.

As I can see from the code, two places (tcp_v6_syn_recv_sock and
dccp_v6_request_recv_sock) that call this one already run with
BHs disabled, so it's safe to call __inet_inherit_port there.

Besides (in case I missed smth with code review) the calltrace
tcp_v6_syn_recv_sock
 `- tcp_v4_syn_recv_sock
     `- __inet_inherit_port
and the similar for DCCP are valid, but assumes BHs to be disabled.

The driver stores the PCI resource address into 'unsigned long' variable before
calling ioremap()  on it. This warrants a kernel oops when the registers are
accessed on PPC 44x platforms which (being 32-bit) have PCI memory space mapped
beyond 4 GB.

The arch/ppc/ kernel has a fixup in ioremap() that creates an illusion of the
PCI memory resources are mapped below 4 GB, but arch/powerpc/ code got rid of
this trick, having instead CONFIG_RESOURCES_64BIT enabled.

This patch is a largely cosmetic cleanup of the TIPC reference
table code.
- The object reference field in each table entry is now single
  32-bit integer instead of a union of two 32-bit integers.
- Variable naming has been made more consistent.
- Error message output has been made more consistent.
- Useless #includes have been eliminated.

drivers/net/sb1000.c has lots of inlined static functions.

Mst of them are used at initialization, wait for some
hardware register to change (wait using yield, sleep etc),
or do slow port-based I/O. Inlining thse "for speed" makes no sense.

This patch removes "inline" from biggest static function
(regardless of number of callsites - gcc nowadays auto-inlines
statics with one callsite).

Problem:     A STARTLAN command from the adapter may arrive while a
             qeth recovery is currently running with a failed qeth
             STARTLAN. Usually qeth schedules a recovery when
             receiving a STARTLAN command from the adapter. But
             another recovery scheduled while a recovery is already
             running never starts. Thus the qeth-administered
             lan_online flag remains zero in this scenario, even
             though the adapter-STARTLAN has happened.
Solution:    Set lan_online flag for a received STARTLAN from the
             adapter in case scheduled recovery does not start.
