5a81e6a171 vfs: fix uninitialized flags in splice_to_pipe()
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:

 1) In order to avoid problems in the future, make cgroup bpf overriding
    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.

 7) Fix erroneous emission of NETEVENT_DELAY_PROBE_TIME_UPDATE when we
    aren't even updating that sysctl value. From Marcus Huewe.

 8) Fix endian bugs in ibmvnic driver, from Thomas Falcon.

e27ee2b16b Bluetooth: btqcomsmd: Allow driver to build if COMPILE_TEST is enabled
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.

89ab37b489 Bluetooth: hci_bcm: Add support for BCM2E95 and BCM2E96
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.

9dcbc313cd Bluetooth: Fix NULL pointer dereference in bt_sock_recvmsg
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.

a4ccc9e33d Bluetooth: btusb: Configure Marvell to use one of the pins for oob wakeup
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.

fd913ef7ce Bluetooth: btusb: Add out-of-band wakeup support
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

ffed21bcee ixgbe: Don't bother clearing buffer memory for descriptor rings
This patch makes it so that we don't need to bother with clearing the
memory out for the descriptor rings.  The general idea is to only free
buffers associated with buffers in use which are located between the
next_to_clean and next_to_use or next_to_alloc values.  Everything outside
of those regions can be safely ignored since they should have no buffers
associated with them.

The advantage to doing things this way is that is should speed up bring-up
and tear-down of the rings.  Specifically we can avoid the 512 or more
cycles required to memset the rings in tear-down.  In the bring-up phase we
then clear the memory as a part of initialization.  The general idea is
that the clearing in initialization can act as a prefetch of sorts for the
buffer info structures so they are in the local CPU when we go to populate
them.  This should help to improve overall time needed to perform a
suspend/resume.

1.  It avoids the memcpy and skb->head allocation for small packets which

2.  It avoids the memcpy, skb->head allocation, and eth_get_headlen

It also provides a means of validating the legacy Rx path in the event that

3f91a89d42 powerpc/64: Disable use of radix under a hypervisor
Currently, if the kernel is running on a POWER9 processor under a
hypervisor, it may try to use the radix MMU even though it doesn't have
the necessary code to do so (it doesn't negotiate use of radix, and it
doesn't do the H_REGISTER_PROC_TBL hcall).  If the hypervisor supports
both radix and HPT, then it will set up the guest to use HPT (since the
guest doesn't request radix in the CAS call), but if the radix feature
bit is set in the ibm,pa-features property (which is valid, since
ibm,pa-features is defined to represent the capabilities of the
processor) the guest will try to use radix, resulting in a crash when
it turns the MMU on.

This makes the minimal fix for the current code, which is to disable
radix unless we are running in hypervisor mode.
