This is a follow-up patch to 3630d40067
("ipv6: rt6_check_neigh should successfully verify neigh if no NUD
information are available").
Since the removal of rt->n in rt6_info we can end up with a dst ==
NULL in rt6_check_neigh. In case the kernel is not compiled with
CONFIG_IPV6_ROUTER_PREF we should also select a route with unkown
NUD state but we must not avoid doing round robin selection on routes
with the same target. So introduce and pass down a boolean ``do_rr'' to
indicate when we should update rt->rr_ptr. As soon as no route is valid
we do backtracking and do a lookup on a higher level in the fib trie.
v2:
a) Improved rt6_check_neigh logic (no need to create neighbour there)
and documented return values.
v3:
a) Introduce enum rt6_nud_state to get rid of the magic numbers
(thanks to David Miller).
b) Update and shorten commit message a bit to actualy reflect
the source.

Several of these patches were rebased in order to correct style issues.
Only stylistic changes were made versus the patches which were in linux-next
for two weeks. The rebases have been in linux-next for 3 days and have
passed my regressions.
The bulk of these are RDMA fixes and improvements. There's also some
additions on the extended attributes front to support some additional
namespaces and a new option for TCP to force allocation of mount requests
from a priviledged port.

were added to 3.10, which includes several bug fixes that have been
marked for stable.
As for new features, there were a few, but nothing to write to LWN about.
These include:
New function trigger called "dump" and "cpudump" that will cause
ftrace to dump its buffer to the console when the function is called.
The difference between "dump" and "cpudump" is that "dump" will dump
the entire contents of the ftrace buffer, where as "cpudump" will only
dump the contents of the ftrace buffer for the CPU that called the function.
Another small enhancement is a new sysctl switch called "traceoff_on_warning"
which, when enabled, will disable tracing if any WARN_ON() is triggered.
This is useful if you want to debug what caused a warning and do not
want to risk losing your trace data by the ring buffer overwriting the
data before you can disable it. There's also a kernel command line
option that will make this enabled at boot up called the same thing.

This reverts commit d2aae8477c.
It is completely and utterly broken. Module install should not build
any files, and adding broken dependencies to "help" it build files is
complete and utter sh*t.
The kernel should not be built by root, and "make install" and "make
module_install" (that for obvious reasons need to be run as root)
absolutely must not build any files. They should only ever copy the
already-built files over.
So having dependencies for the install targets is wrong, wrong, wrong.
If you try to install a kernel without building it first, you *should*
get errors. The build system shouldn't try to help root build the files.

Userspace may produce vectors greater than MAX_SKB_FRAGS. When we try to
linearize parts of the skb to let the rest of iov to be fit in
the frags, we need count copylen into linear when calling macvtap_alloc_skb()
instead of partly counting it into data_len. Since this breaks
zerocopy_sg_from_iovec() since its inner counter assumes nr_frags should
be zero at beginning. This cause nr_frags to be increased wrongly without
setting the correct frags.
This bug were introduced from b92946e291
(macvtap: zerocopy: validate vectors before building skb).

According to the commit 16b0dc29c1
(dummy: fix rcu_sched self-detected stalls)
Eric Dumazet fix the problem in dummy, but the ifb will occur the
same problem like the dummy modules.
Trying to "modprobe ifb numifbs=30000" triggers :
INFO: rcu_sched self-detected stall on CPU
After this splat, RTNL is locked and reboot is needed.
We must call cond_resched() to avoid this, even holding RTNL.
