1. Use c_index and ring->c_index to determine how many TxCBs/TxBDs are

- c_index = the current value of TDMA_CONS_INDEX
- TDMA_CONS_INDEX is HW-incremented and auto-wraparound (0x0-0xFFFF)
- ring->c_index = __bcmgenet_tx_reclaim() cleaned up to this point on
the previous invocation
2. Add bcmgenet_tx_ring->clean_ptr
- index of the next TxCB to be cleaned
- incremented as TxCBs/TxBDs are processed
- value always in range [ring->cb_ptr, ring->end_ptr]
3. Fix incrementing of dev->stats.tx_packets
- should be incremented only when tx_cb_ptr->skb != NULL
These changes simplify __bcmgenet_tx_reclaim(). Furthermore, Tx ring size
can now be any value.
With the old code, Tx ring size had to be a power-of-2:
num_tx_bds = ring->size;
c_index &= (num_tx_bds - 1);
last_c_index &= (num_tx_bds - 1);

In seq_buf_bprintf(), bstr_printf() is used to copy the format into the
buffer remaining in the seq_buf structure. The return of bstr_printf()
is the amount of characters written to the buffer excluding the '\0',
unless the line was truncated!
If the line copied does not fit, it is truncated, and a '\0' is added
to the end of the buffer. But in this case, '\0' is included in the length
of the line written. To know if the buffer had overflowed, the return
length will be the same or greater than the length of the buffer passed in.
The check in seq_buf_bprintf() only checked if the length returned from
bstr_printf() would fit in the buffer, as the seq_buf_bprintf() is only
to be an all or nothing command. It either writes all the string into
the seq_buf, or none of it. If the string is truncated, the pointers
inside the seq_buf must be reset to what they were when the function was
called. This is not the case. On overflow, it copies only part of the string.
The fix is to change the overflow check to see if the length returned from
bstr_printf() is less than the length remaining in the seq_buf buffer, and not
if it is less than or equal to as it currently does. Then seq_buf_bprintf()
will know if the write from bstr_printf() was truncated or not.

ipv4/fib_trie: Cleanups to prepare for introduction of key vector
This patch series is meant to mostly just clean up the fib_trie to prepare
it for the introduction of the key_vector. As such there are a number of
minor clean-ups such as reformatting the tnode to match the format once the
key vector is introduced, some optimizations to drop the need for a leaf
parent pointer, and some changes to remove duplication of effort such as
the 2 look-ups that were essentially being done per node insertion.

This change updates the fib_table_lookup function so that it is in sync
with the fib_find_node function in terms of the explanation for the index
check based on the bits value.
I have also updated it from doing a mask to just doing a compare as I have
found that seems to provide more options to the compiler as I have seen it
turn this into a shift of the value and test under some circumstances.
In addition I addressed one minor issue in which we kept computing the key
^ n->key when checking the fib aliases. I pulled the xor out of the loop
in order to reduce the number of memory reads in the lookup. As a result
we should save a couple cycles since the xor is only done once much earlier
in the lookup.

When a CRTC is disabled, no CTL is allocated to it (CRTC->ctl == NULL);
in that case we should not try to FLUSH registers and do nothing instead.
This can happen when we try to move a cursor but the CRTC's CTL

It can also happens when we .atomic_check()/.atomic_flush() on a
disabled CRTC.
A CTL needs to be kept as long as the CRTC is alive. Releasing it

Commit 8634b51f6c (locks: convert lease handling to file_lock_context)
introduced a regression in the handling of lease upgrade/downgrades.
In the event that we already have a lease on a file and are going to
either upgrade or downgrade it, we skip doing any list insertion or
deletion and simply re-call lm_setup on the existing lease.
As of commit 8634b51f6c however, we end up calling lm_setup on the
lease that was passed in, instead of on the existing lease. This causes
us to leak the fasync_struct that was allocated in the event that there
was not already an existing one (as it always appeared that there
wasn't one).

should expect being called in suspended state, and properly wake the
system up when this is the case.
Set IRQF_COND_SUSPEND flag when registering the IRQ handler to inform
irq core that it can safely be called while the system is suspended.

The IRQ line used by the RTC device is usually shared with the system timer
(PIT) on at91 platforms.
Since timers are registering their handlers with IRQF_NO_SUSPEND, we should
expect being called in suspended state, and properly wake the system up
when this is the case.
Set IRQF_COND_SUSPEND flag when registering the IRQ handler to inform
irq core that it can safely be called while the system is suspended.

Export pm_system_wakeup function to allow irq handlers to deal with system
wakeup.
This is needed for shared IRQ lines where one of the handler is registered
with IRQF_NO_SUSPEND, while the other ones want to configure it as a wakeup
source.
In this specific case, irq core does not handle the wakeup process and
leave the decision to each irq handler.

Currently the list is traversed using rcu variant. That is not correct
since dev_set_mac_address can be called which eventually calls
rtmsg_ifinfo_build_skb and there, skb allocation can sleep. So fix this
by remove the rcu usage here.
