Last minute urgent pull request to prevent file system corruption
on Nokia N900.

Looks like we have a GPMC bus timing bug that has gone unnoticed
because of bootloader configured registers until few days ago. We
are not detecting the onenand clock rate properly unless we have
CONFIG_OMAP_GPMC_DEBUG set and this causes onenand corruption
that can be easily be reproduced.

There seems to be also an additional bug still lurking around for
onenand corruption. But that is still being investigated and
it does not seem to be GPMC timings related.

Meanwhile, it would be good to get this fix into v4.4 to prevent
wrong timings from corrupting onenand.

  The solution is to call ftrace_release_mod() on the failing module in

  allocations made for that module, and nothing if ftrace_module_init()
  wasn't called yet for that module.

  Note, once do_init_module() is called, the MODULE_GOING notifiers are
  called for the failed module, which calls into the ftrace code to do
  the proper clean up (basically calling ftrace_release_mod())"

  ftrace/module: Call clean up function when module init fails early

If the module init code fails after calling ftrace_module_init() and before
calling do_init_module(), we can suffer from a memory leak. This is because
ftrace_module_init() allocates pages to store the locations that ftrace
hooks are placed in the module text. If do_init_module() fails, it still
calls the MODULE_GOING notifiers which will tell ftrace to do a clean up of
the pages it allocated for the module. But if load_module() fails before
then, the pages allocated by ftrace_module_init() will never be freed.

Call ftrace_release_mod() on the module if load_module() fails before
getting to do_init_module().

Commit 69fb4dca ("power: Add an axp20x-usb-power driver") introduced a
new driver for the USB power supply used on various Allwinner based SBCs.
However, the driver was not added to multi_v7_defconfig which breaks USB
support for some boards (e.g. LeMaker BananaPi) as the kernel will now
turn off the USB power supply during boot by default if the driver isn't
present. (This was not the case in linux 4.3 or lower where the USB power
was always left on.)

Hence, add the driver to multi_v7_defconfig in order to keep USB support
working on those boards that require it.

When mapping a non-page-aligned scatterlist entry, we copy the original
offset to the output DMA address before aligning it to hand off to
iommu_map_sg(), then later adding the IOVA page address portion to get
the final mapped address. However, when the IOVA page size is smaller
than the CPU page size, it is the offset within the IOVA page we want,
not that within the CPU page, which can easily be larger than an IOVA
page and thus result in an incorrect final address.

Fix the bug by taking only the IOVA-aligned part of the offset as the
basis of the DMA address, not the whole thing.

Commit 0976c946
"arm/versatile: Fix versatile irq specifications"
has an off-by-one error on the Versatile AB that has
been regressing the Versatile AB hardware for some time.

However it seems like the interrupt assignments have
never been correct and I have now adjusted them according
to the specification. The masks for the valid interrupts
made it impossible to assign the right SIC interrupt
for the MMCI, so I went in and fixed these to correspond
to the specifications, and added references if anyone
wants to double-check.

Due to the Versatile PB including the Versatile AB
as a base DTS file, we need to override and correct
some values to correspond to the actual changes in the
hardware.

For the Versatile PB I don't think the IRQ line
assignment for MMCI has ever been correct for either of
the two MMCI blocks. It would be nice if someone with the
physical PB board could test this.

Patch tested on the Versatile AB, QEMU for Versatile AB
and QEMU for Versatile PB.

These latencies were set to 2 since the Nomadik platform was merged,

that is why the crash comes now.

Patch 3759824d ("tcp: PRR uses CRB mode by default and SS mode
conditionally") introduced a bug that cwnd may become 0 when both
inflight and sndcnt are 0 (cwnd = inflight + sndcnt). This may lead
to a div-by-zero if the connection starts another cwnd reduction
phase by setting tp->prior_cwnd to the current cwnd (0) in
tcp_init_cwnd_reduction().

To prevent this we skip PRR operation when nothing is acked or
sacked. Then cwnd must be positive in all cases as long as ssthresh
is positive:

1) The proportional reduction mode
   inflight > ssthresh > 0

2) The reduction bound mode
  a) inflight == ssthresh > 0

  b) inflight < ssthresh
     sndcnt > 0 since newly_acked_sacked > 0 and inflight < ssthresh

Therefore in all cases inflight and sndcnt can not both be 0.
We check invalid tp->prior_cwnd to avoid potential div0 bugs.

In reality this bug is triggered only with a sequence of less common
events.  For example, the connection is terminating an ECN-triggered
cwnd reduction with an inflight 0, then it receives reordered/old
ACKs or DSACKs from prior transmission (which acks nothing). Or the
connection is in fast recovery stage that marks everything lost,
but fails to retransmit due to local issues, then receives data
packets from other end which acks nothing.
