A plain 32 bit integer will overflow for values over 4GiB.
Change the plain integer size to the appropriate size type in
ntb_set_mw. Change the type of the size parameter and two local
variables used for size.
Even if there is no overflow, a size of zero is invalid here.

When the remote side is not up, we do not have all the context for the

Currently the debugfs does not have files for all NTB transport queue
pairs. When there are multiple NTBs present in a system, the QP names
of the last transport clobber the names of previously added transport
QPs. Only the last added QPs can be observed via debugfs.
Create a directory per NTB transport to associate the QPs with that
transport. Name the directory the same as the PCI device.

It was possible for a synchronous update of the RX index in the error
case to get ahead of the asynchronous RX index update in the normal
case. Change the RX processing to preserve an RX completion order.
There were two error cases. First, if a buffer is not present to
receive data, there would be no queue entry to preserve the RX
completion order. Instead of dropping the RX frame, leave the RX frame
in the ring. Schedule RX processing when RX entries are enqueued, in
case there are RX frames waiting in the ring to be received.
Second, if a buffer is too small to receive data, drop the frame in the
ring, mark the RX entry as done, and indicate the error in the RX entry
length. Check for a negative length in the receive callback in
ntb_netdev, and count occurrences as rx_length_errors.

Pull MIPS fixes from Ralf Baechle:
"Another round of MIPS fixes for 4.2. No area does particularly stand
out but we have a two unpleasant ones:
- Kernel ptes are marked with a global bit which allows the kernel to
share kernel TLB entries between all processes. For this to work
both entries of an adjacent even/odd pte pair need to have the
global bit set. There has been a subtle race in setting the other
entry's global bit since ~ 2000 but it take particularly
pathological workloads that essentially do mostly vmalloc/vfree to
trigger this.
This pull request fixes the 64-bit case but leaves the case of 32
bit CPUs with 64 bit ptes unsolved for now. The unfixed cases
affect hardware that is not available in the field yet.
- Instruction emulation requires loading instructions from user space
but the current fast but simplistic approach will fail on pages
that are PROT_EXEC but !PROT_READ. For this reason we temporarily
do not permit this permission and will map pages with PROT_EXEC |
PROT_READ.

and the short log explains them well"

An RX stall issue was seen on Lancer adapters, when RXQs are destroyed
while they are in an "out of buffer" state. This patch fixes this issue
by posting 64 buffers to each RXQ before destroying them in the close path.
This is done after ensuring that no more new packets are selected for
transfer to the RXQs by disabling interface filters.

HW issues were observed on Lancer adapters if IFACE filters
(flags, mac addrs etc) are enabled *before* creating RXQs. This patch
changes the driver design by enabling filters in be_open() --
instead of be_setup() -- after RXQs are created and buffers posted.
Two new wrapper functions, be_enable_if_filters() and
be_disable_if_filters() are introduced to enable/disable IFACE filters in
be_open()/be_close() respectively. In be_setup() the IFACE is now created
only with the RSS flag.

virtio declares support for NETIF_F_FRAGLIST, but assumes
that there are at most MAX_SKB_FRAGS + 2 fragments which isn't
always true with a fraglist.
A longer fraglist in the skb will make the call to skb_to_sgvec overflow
the sg array, leading to memory corruption.

following static checker warning:
.../stmmac/dwmac-ipq806x.c:314 ipq806x_gmac_probe()
warn: double left shift '1 << (1 << gmac->id)'
The NSS_COMMON_CLK_SRC_CTRL_OFFSET macro is used once as an offset, and
once as a mask, which is a bug indeed. We'll fix it by defining the
offset as the real offset value and computing the mask from it when
required.

Prior to this patch, rx buffer size for each rx queue
of an interface is configurable through dts bindings.
But for an interface, the first rx queue's rx buffer
size is always the usual MTU size (plus usual overhead)
and page size for the remaining rx queues (if they are
enabled by specifying a non-zero rx queue depth dts
binding of the corresponding interface). This patch
removes the rx buffer size configuration capability.

because it means the thread may go to sleep before inflight_packets is

The clocks are initially active and thus the device is marked active.
This still keeps the PM refcount at 0, the pm_runtime_put_autosuspend()
call at the end of probe then leaves us with an invalid refcount of -1,
which in turn leads to the device staying in suspended state even though
netdev open had been called.
Fix this by initializing the refcount to be coherent with the initial
device status.

VBT version 196 increased the size of common_child_dev_config. The parser
code assumed that the size of this structure would not change.
The modified code now copies the amount needed based on the VBT version,
and emits a debug message if the VBT version is unknown (too new);
since the struct config block won't shrink in newer versions it should
be harmless to copy the maximum known size in such cases, so that's
what we do, but emitting the warning is probably sensible anyway.
In the longer run it might make sense to modify the parser code to
use a version/feature mapping, rather than hardcoding things like this,
but for now the variants are fairly managable.
This fixes a regression introduced in

The I2C core always reports the MODALIAS uevent as "i2c:<client name"
regardless if the driver was matched using the I2C id_table or the
of_match_table. So technically there's no need for a driver to export
the OF table since currently it's not used.
In fact, the I2C device ID table is mandatory for I2C drivers since
a i2c_device_id is passed to the driver's probe function even if the
I2C core used the OF table to match the driver.
And since the I2C core uses different tables, OF-only drivers needs to
have duplicated data that has to be kept in sync and also the dev node
compatible manufacturer prefix is stripped when reporting the MODALIAS.
To avoid the above, the I2C core behavior may be changed in the future
to not require an I2C device table for OF-only drivers and report the
OF module alias. So, it's better to also export the OF table to prevent
breaking module autoloading if that happens.

be built into the module or udev won't have the necessary information
to auto load the correct module when the device is added.

The commit 8c7a075da9f7980cc95ffcd7e6621d4a87f20f40
"drm/i2c: tda998x: use drm_hdmi_avi_infoframe_from_display_mode()"
also uses hdmi_avi_infoframe_pack() to create the AVI infoframe.
This function sets the checksum of the frame and this breaks
the second calculation of the checksum done in tda998x_write_if().

Pull md fixes from Neil Brown:
"Three more fixes for md in 4.2
Mostly corner-case stuff.
One of these patches is for a CVE: CVE-2015-5697
I'm not convinced it is serious (data leak from CAP_SYS_ADMIN ioctl)
but as people seem to want to back-port it, I've included a minimal
version here. The remainder of that patch from Benjamin is
code-cleanup and will arrive in the 4.3 merge window"
* tag 'md/4.2-rc5-fixes' of git://neil.brown.name/md:
md/raid5: don't let shrink_slab shrink too far.
md: use kzalloc() when bitmap is disabled
md/raid1: extend spinlock to protect raid1_end_read_request against inconsistencies
