If a hardware Tx timestamp is requested, an uninitialized
workqueue entry may be scheduled, especially on an 82598 adapter.
Add a check for a PTP clock to avoid that. Also only apply the
unlikely to the first term of the conditional. That will make the
rest of the checks be in the cold path.

After sending a RTR frame the TX mailbox becomes a RX_EMPTY mailbox. To avoid
side effects when the RX-FIFO is full, this patch puts the TX mailbox into
TX_INACTIVE mode in the transmission complete interrupt handler. This, of
course, leaves a race window between the actual completion of the transmission
and the handling of tx-complete interrupt. However this is the best we can do
without busy polling the tx complete interrupt.

This patch implements the workaround mentioned in ERR005829:
ERR005829: FlexCAN: FlexCAN does not transmit a message that is enabled to
be transmitted in a specific moment during the arbitration process.
Workaround: The workaround consists of two extra steps after setting up a
message for transmission:
Step 8: Reserve the first valid mailbox as an inactive mailbox (CODE=0b1000).
If RX FIFO is disabled, this mailbox must be message buffer 0. Otherwise, the
first valid mailbox can be found using the "RX FIFO filters" table in the
FlexCAN chapter of the chip reference manual.
Step 9: Write twice INACTIVE code (0b1000) into the first valid mailbox.

Apparently mailboxes may contain random data at startup, causing some of them
being prepared for message reception. This causes overruns being missed or even
confusing the IRQ check for trasmitted messages, increasing the transmit
counter instead of the error counter.
This patch initializes all mailboxes after the FIFO as RX_INACTIVE.

====================
This pull requests makes the following changes:
* Add simple weighted fail-over scheduler.
- Unlike other IPVS schedulers this offers fail-over rather than load
balancing. Connections are directed to the appropriate server based
solely on highest weight value and server availability.
- Thanks to Kenny Mathis
* Support IPv6 real servers in IPv4 virtual-services and vice versa
- This feature is supported in conjunction with the tunnel (IPIP)
forwarding mechanism. That is, IPv4 may be forwarded in IPv6 and
vice versa.
- The motivation for this is to allow more flexibility in the
choice of IP version offered by both virtual-servers and
real-servers as they no longer need to match: An IPv4 connection from an
end-user may be forwarded to a real-server using IPv6 and vice versa.
- Further work need to be done to support this feature in conjunction
with connection synchronisation. For now such configurations are
not allowed.
- This change includes update to netlink protocol, adding a new
destination address family attribute. And the necessary changes
to plumb this information throughout IPVS.
- Thanks to Alex Gartrell and Julian Anastasov

While tracking down the MAX_AH_AUTH_LEN crash in an old kernel
I thought that this limit was rather arbitrary and we should
just get rid of it.
In fact it seems that we've already done all the work needed
to remove it apart from actually removing it. This limit was
there in order to limit stack usage. Since we've already
switched over to allocating scratch space using kmalloc, there
is no longer any need to limit the authentication length.
This patch kills all references to it, including the BUG_ONs
that led me here.

That field has been deprecated in favour of getting the necessary
information from ACPI/DT.
However, we still need to deal systems that are PCI only (no ACPI to back
up). In order to support such systems, we allow the DMA filter function and
its corresponding parameter via pxa2xx_spi_master platform data. Then when
the pxa2xx_spi_dma_setup() doesn't find the channel via ACPI, it falls back
to use the given filter function.

Old devices used to have NVRAM at the very end of flash and they could
be unaligned (starting at some offset in a block).
In new devices NVRAM can be located quite randomly, however it seems to
always start at the beginning of a block. For example Netgear R6250 has
NVRAM located right after the bootloader, before the kernel partition.

This patch introduces a new default FIQ handler that is structured in a
similar way to the existing ARM exception handler and result in the FIQ
being handled by C code running on the SVC stack (despite this code run
in the FIQ handler is subject to severe limitations with respect to
locking making normal interaction with the kernel impossible).
This default handler allows concepts that on x86 would be handled using
NMIs to be realized on ARM.

Not all filesystems now provide the rename i_op - ext4 for one - but rather
provide the rename2 i_op. CacheFiles checks that the filesystem has rename
and so will reject ext4 now with EPERM:
CacheFiles: Failed to register: -1
Fix this by checking for rename2 as an alternative. The call to vfs_rename()
actually handles selection of the appropriate function, so we needn't worry
about that.
Turning on debugging shows:
[cachef] ==> cachefiles_get_directory(,,cache)
[cachef] subdir -> ffff88000b22b778 positive
[cachef] <== cachefiles_get_directory() = -1 [check]
