Flags (PIPE_BUF_FLAG_PACKET, PIPE_BUF_FLAG_GIFT) could remain on the
unused part of the pipe ring buffer. Previously splice_to_pipe() left
the flags value alone, which could result in incorrect behavior.
Uninitialized flags appears to have been there from the introduction of
the splice syscall.

Pull networking fixes from David Miller:

explicit using BPF_F_ALLOW_OVERRIDE. From Alexei Staovoitov.
2) LLC sets skb->sk without proper skb->destructor and this explodes,
fix from Eric Dumazet.
3) Make sure when we have an ipv4 mapped source address, the
destination is either also an ipv4 mapped address or
ipv6_addr_any(). Fix from Jonathan T. Leighton.
4) Avoid packet loss in fec driver by programming the multicast filter
more intelligently. From Rui Sousa.
5) Handle multiple threads invoking fanout_add(), fix from Eric
Dumazet.
6) Since we can invoke the TCP input path in process context, without
BH being disabled, we have to accomodate that in the locking of the
TCP probe. Also from Eric Dumazet.

The driver only has runtime but no build time dependency with QCOM_SMD &&
QCOM_WCNSS_CTRL. So it can be built for testing purposes if COMPILE_TEST
option is enabled.
This is useful to have more build coverage and make sure that the driver
is not affected by changes that could cause build regressions.

The BCM2E96 ID is used by the ECS EF20 laptop, and BCM2E95 is present
in the Weibu F3C. Both are now logged as:
hci0: BCM: chip id 82
hci0: BCM43341B0 (002.001.014) build 0000
hci0: BCM (002.001.014) build 0158
The ECS vendor kernel predates the host-wakeup support in hci_bcm but
it explicitly has a comment saying that the GPIO assignment needs to be
reordered for BCM2E96:
1. (not used in vendor driver)
2. Device wakeup
3. Shutdown
For both devices in question, the DSDT has these GPIOs listed in order
of GpioInt, GpioIo, GpioIo. And if we use the first one listed (GpioInt)
as the host wakeup, that interrupt handler fires while doing bluetooth
I/O.
I am assuming the convention of GPIO ordering has been changed for these
new device IDs, so lets use the new ordering on such devices.

As per the comment in include/linux/net.h, the recvfrom handlers
should expect msg_name to be NULL. However, bt_sock_recvmsg()
is currently not checking it, which could lead to a NULL pointer
dereference.
The following NULL pointer dereference was produced while testing
L2CAP datagram reception. Note that the kernel is tainted due to
the r8723bs module being inserted. However, it seems the fix still
applies.

The Marvell devices may have many gpio pins, and hence for wakeup
on these out-of-band pins, the chip needs to be told which pin is
to be used for wakeup, using an hci command.
Thus, we read the pin number etc from the device tree node and send
a command to the chip.

Some onboard BT chips (e.g. Marvell 8997) contain a wakeup pin that
can be connected to a gpio on the CPU side, and can be used to wakeup
the host out-of-band. This can be useful in situations where the
in-band wakeup is not possible or not preferable (e.g. the in-band
wakeup may require the USB host controller to remain active, and
hence consuming more system power during system sleep).
The oob gpio interrupt to be used for wakeup on the CPU side, is
read from the device tree node, (using standard interrupt descriptors).
A devcie tree binding document is also added for the driver. The
compatible string is in compliance with
Documentation/devicetree/bindings/usb/usb-device.txt

In commit 76624175dcae ("arm64: uaccess: consistently check object sizes"),
the object size checks are moved outside the access_ok() so that bad
destinations are detected before hitting the "memset(dest, 0, size)" in the
copy_from_user() failure path.
This makes the same change for arm, with attention given to possibly
extracting the uaccess routines into a common header file for all
architectures in the future.

wbt_disable_default() calls del_timer_sync() to wait for the wbt
timer to finish before disabling throttling. We can't do this with
IRQs disable. This fixes a lockdep splat on boot, if non-root

Currently, the IPID and Syndrome are printed on the same line as the
Address. There are cases when we can have a valid Syndrome but not a
valid Address.
For example, the MCA_SYND register can be used to hold more detailed
error info that the hardware folks can use. It's not just DRAM ECC
syndromes. There are some error types that aren't related to memory that
may have valid syndromes, like some errors related to links in the Data
Fabric, etc.
In these cases, the IPID and Syndrome are not printed at the same log
level as the rest of the stanza, so users won't see them on the console.
Console:
[Hardware Error]: CPU:16 (17:1:0) MC22_STATUS[Over|CE|MiscV|-|-|-|-|SyndV|-]: 0xd82000000002080b
[Hardware Error]: Power, Interrupts, etc. Extended Error Code: 2
Dmesg:

Print the IPID first and on a new line. The IPID should always be
printed on SMCA systems. The Syndrome will then be printed with the IPID
and at the same log level when valid:
[Hardware Error]: CPU:16 (17:1:0) MC22_STATUS[Over|CE|MiscV|-|-|-|-|SyndV|-]: 0xd82000000002080b

Although irqreturn_t is an enum, we treat it (and its enumeration
constants) as a bitmask.
However, bad_action_ret() uses a less-than operator to determine whether
an irqreturn_t falls within allowable bit values, which means we need to
know the signededness of an enum type to read the logic, which is
implementation-dependent.
This change explicitly uses an unsigned type for the comparison. We do
this instead of changing to a bitwise test, as the latter compiles to
increased instructions in this hot path.
It looks like we get the correct behaviour currently (bad_action_ret(-1)
returns 1), so this is purely a readability fix.

A bug fix to the MSIx handling in vfio added references to functions
that may not be defined if MSI is disabled in the kernel, resulting in
this link error:
drivers/built-in.o: In function `vfio_msi_set_vector_signal':
:(.text+0x450808): undefined reference to `get_cached_msi_msg'
:(.text+0x45080c): undefined reference to `write_msi_msg'
As suggested by Alex Williamson, add stub implementations for
get_cached_msi_msg() and pci_write_msi_msg().
In case this bugfix gets backported, please note that the #ifdef
has changed over time, originally both functions were implemented
in drivers/pci/msi.c and controlled by CONFIG_PCI_MSI, while nowadays
get_cached_msi_msg() is part of the generic MSI support and can be
used without PCI.

Let's disable all scaling that requires horizontal decimation with
higher factor than 4, until we have better estimates of what we can
and can not do. However, NV12 color format appears to work Ok with
all decimation factors.
When decimating horizontally by more that 4 the dss is not able to
fetch the data in burst mode. When this happens it is hard to tell if
there enough bandwidth. Despite what theory says this appears to be
true also for 16-bit color formats.

Move drm_atomic_helper_commit_modeset_enables() call to before
drm_atomic_helper_commit_planes() call and have a
omap_atomic_wait_for_completion() call after both.
With the current dss dispc implementation we have to enable the new
modeset before we can commit planes. The dispc ovl configuration
relies on the video mode configuration been written into the HW when
the ovl configuration is calculated.
This approach is not ideal because after a mode change the plane
update is executed only after the first vblank interrupt. The dispc
implementation should be fixed so that it is able use uncommitted drm
state information. information.
