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.

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.

Now that the rps interrupt locking isn't clearly separated (at elast
conceptually) from all the other interrupt locking having a different
lock stopped making sense: It protects much more than just the rps
workqueue it started out with. But with the addition of VECS the
separation started to blurr and resulted in some more complex locking
for the ring interrupt refcount.
With this we can (again) unifiy the ringbuffer irq refcounts without
causing a massive confusion, but that's for the next patch.
v2: Explain better why the rps.lock once made sense and why no longer,

And kill the comment about it. Queueing work is a barrier type event,
no amount of locking will help in ordering things (as long as we queue
the work after having updated all relevant data structures). Also, the
queue_work works itself as a sufficient memory barrier.
Again on the surface this is just a tiny micro-optimization to reduce
the hold-time of dev_priv->irq_lock. But the better reason is that it
reduces superficial locking and so makes it clearer what we actually
need for correctness.

It's racy: There's no guarantee that we won't walk this code (due to a
pch fifo underrun interrupt) while someone is changing the pointers
around.
The only reason we do this is to use the righ crtc for the pch fifo
underrun accounting. But we never expose this to userspace, so
essentially no one really cares if we use the "wrong" crtc.
So let's just rip it out.
With this patch fifo underrun code will always use crtc A for tracking
underruns on the (only) pch transcoder on LPT.

Same treatment as for SERR_INT: If we clear only the bit for the pipe
we're enabling (but unconditionally) then we can always check for
possible underruns after having disabled the interrupt. That way pipe
underruns won't be lost, but at worst only get reported in a delayed
fashion.
v2: The same logic bug as in the SERR handling change also existed
here. The same bugfix of only reporting missed underruns when the
error interrupt was masked applies, too.
v3: Do the same fixes as for the SERR handling that Paulo suggested in
his review:
- s/%i/%c/ fix in the debug output
- move the DE_ERR_INT_IVB read into the respective if block

The current code won't report any fifo underruns on cpt if just one
pipe has fifo underrun reporting disabled. We can't enable the
interrupts, but we can still check the per-transcoder bits and so
report the underrun delayed if:
- We always clear the transcoder's bit (and none of the other bits)
when enabling.
- We check the transcoder's bit after disabling (to avoid racing with
the interrupt handler).
v2: I've forgotten to actually remove the old SERR_INT clearing.
v3: Use transcoder_name as suggested by Paulo Zanoni. Paulo also
noticed a logic bug: When an underrun interrupt fires we report it
both in the interrupt handler and when checking for underruns when
disabling it in cpt_set_fifo_underrun_reporting. But that second check
is only required if the interrupt is disabled and we're switching of
underrun reporting (e.g. because we're disabling the crtc). Hence
check for that condition.
At first I wanted to rework the code to pass that bit of information
from the uppper functions down to cpt_set_fifo_underrun_reporting. But
that turned out too messy. Hence the quick&dirty check whether the
south error interrupt source is masked off or not.
v4: Streamline the control flow a bit.
v5: s/pipe/pch transcoder/ in the dmesg output, suggested by Paulo.
v6: Review from Paulo:
- Reorder the was_enabled assignment to only read the register when we
need it. Also add a comment that we need to do that before updating
the register.
- s/%i/%c/ fix for the debug output.
- Fix the checkpath complaint in the SERR_INT_TRANS_FIFO_UNDERRUN
#define.
v7: Hopefully put that elusive SERR hunk back into this patch, spotted
by Paulo.

This way all changes to SDEIMR all go through the same function, with
the exception of the (single-threaded) setup/teardown code.
For paranoia again add an assert_spin_locked.
v2: For even more paranoia also sprinkle a spinlock assert over
cpt_can_enable_serr_int since we need to have that one there, too.
v3: Fix the logic of interrupt enabling, add enable/disable macros for
the simple cases in the fifo code and add a comment. All requested by
Paulo.

Commit 24778be "spi: convert drivers to use bits_per_word_mask" removed
what appeared to be redundant code from many drivers. However, it
appears that in the spi-bitbang case, these functions are required by
the spi-bitbang core, even if they don't do anything. Restore them.
For 3.12, the spi-bitbang core should be adjusted not to require these
callbacks to exist if they don't need to do anything.
This is the equivalent of Michal Simek's patch "spi/xilinx: Revert
master->setup function removal", applied to other affected drivers.
