Commit 0933a578cd55 ("rds: tcp: use sock_create_lite() to create the
accept socket") has a reference counting issue in TCP socket creation
when accepting a new connection. The code uses sock_create_lite() to
create a kernel socket. But it does not do __module_get() on the
socket owner. When the connection is shutdown and sock_release() is
called to free the socket, the owner's reference count is decremented
and becomes incorrect. Note that this bug only shows up when the socket
owner is configured as a kernel module.

When run under QEMU, calling mfctl(16) creates some overhead because the
qemu timer has to be scaled and moved into the register. This patch
reduces the number of calls to mfctl(16) by moving the calls out of the
loops.
Additionally, increase the minimal time interval to 8000 cycles instead
of 500 to compensate possible QEMU delays when delivering interrupts.

The architecture specification says (for 64-bit systems): PDC is a per
processor resource, and operating system software must be prepared to
manage separate pointers to PDCE_PROC for each processor. The address
of PDCE_PROC for the monarch processor is stored in the Page Zero
location MEM_PDC. The address of PDCE_PROC for each non-monarch
processor is passed in gr26 when PDCE_RESET invokes OS_RENDEZ.
Currently we still use one PDC for all CPUs, but in case we face a
machine which is following the specification let's warn about it.

The change to flush_kernel_vmap_range() wasn't sufficient to avoid the
SMP stalls. The problem is some drivers call these routines with
interrupts disabled. Interrupts need to be enabled for flush_tlb_all()
and flush_cache_all() to work. This version adds checks to ensure
interrupts are not disabled before calling routines that need IPI
interrupts. When interrupts are disabled, we now drop into slower code.
The attached change fixes the ordering of cache and TLB flushes in
several cases. When we flush the cache using the existing PTE/TLB
entries, we need to flush the TLB after doing the cache flush. We don't
need to do this when we flush the entire instruction and data caches as
these flushes don't use the existing TLB entries. The same is true for
tmpalias region flushes.
The flush_kernel_vmap_range() and invalidate_kernel_vmap_range()
routines have been updated.
Secondly, we added a new purge_kernel_dcache_range_asm() routine to
pacache.S and use it in invalidate_kernel_vmap_range(). Nominally,
purges are faster than flushes as the cache lines don't have to be
written back to memory.
Hopefully, this is sufficient to resolve the remaining problems due to
cache speculation. So far, testing indicates that this is the case. I
did work up a patch using tmpalias flushes, but there is a performance
hit because we need the physical address for each page, and we also need
to sequence access to the tmpalias flush code. This increases the
probability of stalls.

'default false' should be 'default n', though they happen to have the
same effect here, due to undefined symbols ('false' in this case)
evaluating to n in a tristate sense.
Remove the default instead of changing it. bool and tristate symbols

In the scheduler config command, the meaning of tid == 0xf was intended
to indicate the configuration is for management frames. However,
tid == 0xf was also used for the multicast queue that was meant only
for multicast data frames, which resulted with the FW not encrypting
multicast data frames.
As multicast frames do not have a QoS header, fix this by setting
tid == 0, to indicate that this is a data queue and not management
one.

When the GTK is installed, we install it to HW with the
station ID of the AP.
Mac80211 will try to remove it only after the AP sta is
removed, which will result in a failure to remove key
since we do not have any station for it.
This is a valid situation, but a previous commit removed
the early return and added a return with error value, which
resulted in an error message that is confusing to users.
Remove the error return value.

Trying to collect firmware debug data while firmware
is not loaded causes various errors (e.g. failing NIC access).
This causes even a bigger issue if at that time the
HW radio is off.
In that case, when later turning the radio on, the Driver
fails to read the HW (registers contain garbage values).
(It may be that the CSR_GP_CNTRL_REG_FLAG_RFKILL_WAKE_L1A_EN
bit is cleared on faulty NIC access - since the same behavior
was seen in HW RFKILL toggling before setting that bit.)

We should add the multicast station before adding the
broadcast station.
However, in older FW, the firmware will start beaconing
when we add the multicast station, and since the broadcast
station is not added at this point so the transmission
of the beacon will fail on assert 0x2b00.
This is fixed in later firmware, so make the order
of addition depend on the TLV.

2) Fix an out of bounds access in tail calls in the ppc64 BPF

3) Fix a crash on arm64 on unaligned BPF xadd operations that
could be triggered via interpreter and JIT, from Daniel.
Please not that once you merge net into net-next at some point, there
is a minor merge conflict in test_verifier.c since test cases had
been added at the end in both trees. Resolution is trivial: keep all
the test cases from both trees.

Setting an interface into a VRF fails with 'RTNETLINK answers: File
exists' if one of its VLAN interfaces is already in the same VRF.
As the VRF is an upper device of the VLAN interface, it is also showing
up as an upper device of the interface itself. The solution is to
restrict this check to devices other than master. As only one master
device can be linked to a device, the check in this case is that the
upper device (VRF) being linked to is not the same as the master device
instead of it not being any one of the upper devices.
The following example shows an interface ens12 (with a VLAN interface
ens12.10) being set into VRF green, which behaves as expected:
# ip link add link ens12 ens12.10 type vlan id 10
# ip link set dev ens12 master vrfgreen
# ip link show dev ens12
3: ens12: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel
master vrfgreen state UP mode DEFAULT group default qlen 1000
link/ether 52:54:00:4c:a0:45 brd ff:ff:ff:ff:ff:ff
But if the VLAN interface has previously been set into the same VRF,
then setting the interface into the VRF fails:
# ip link set dev ens12 nomaster
# ip link set dev ens12.10 master vrfgreen
# ip link show dev ens12.10
39: ens12.10@ens12: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500
qdisc noqueue master vrfgreen state UP mode DEFAULT group default
qlen 1000 link/ether 52:54:00:4c:a0:45 brd ff:ff:ff:ff:ff:ff
# ip link set dev ens12 master vrfgreen
RTNETLINK answers: File exists
The workaround is to move the VLAN interface back into the default VRF
beforehand, but it has to be shut first so as to avoid the risk of
traffic leaking from the VRF. This fix avoids needing this workaround.

The 'defconfig_list' is a weird attribute. If the '.config' is
missing, conf_read_simple() iterates over all visible defaults,
then it uses the first one for which fopen() succeeds.
config DEFCONFIG_LIST
string
depends on !UML
option defconfig_list
default "/lib/modules/$UNAME_RELEASE/.config"
default "/etc/kernel-config"
default "/boot/config-$UNAME_RELEASE"
default "$ARCH_DEFCONFIG"
default "arch/$ARCH/defconfig"
However, like other symbols, the first visible default is always
written out to the .config file. This might be different from what
has been actually used.
For example, on my machine, the third one "/boot/config-$UNAME_RELEASE"
is opened, like follows:
$ rm .config
$ make oldconfig 2>/dev/null
scripts/kconfig/conf --oldconfig Kconfig
#
# using defaults found in /boot/config-4.4.0-112-generic
#
*
* Restart config...
*
*
* IRQ subsystem
*
Expose irq internals in debugfs (GENERIC_IRQ_DEBUGFS) [N/y/?] (NEW)
However, the resulted .config file contains the first one since it is
visible:
$ grep CONFIG_DEFCONFIG_LIST .config
CONFIG_DEFCONFIG_LIST="/lib/modules/$UNAME_RELEASE/.config"
In order to stop confusing people, prevent this CONFIG option from
being written to the .config file.

Commit 1fdb92697469 ("Bluetooth: btusb: Use DMI matching for QCA

Testing has shown that this is a false positive and the problems where
caused by issues with the initial fix: commit fd865802c66b ("Bluetooth:
btusb: fix QCA Rome suspend/resume"), which has already been reverted.
So the QCA Rome BT in the Yoga 920 does not need a reset-resume quirk at
all and this commit removes it from the btusb_needs_reset_resume_table.
Note that after this commit the btusb_needs_reset_resume_table is now
empty. It is kept around on purpose, since this whole series of commits
started for a reason and there are actually broken platforms around,
which need to be added to it.

In order to determine if LFENCE is a serializing instruction on AMD
processors, MSR 0xc0011029 (MSR_F10H_DECFG) must be read and the state
of bit 1 checked. This patch will add support to allow a guest to
properly make this determination.
Add the MSR feature callback operation to svm.c and add MSR 0xc0011029
to the list of MSR-based features. If LFENCE is serializing, then the
feature is supported, allowing the hypervisor to set the value of the
MSR that guest will see. Support is also added to write (hypervisor only)
and read the MSR value for the guest. A write by the guest will result in
a #GP. A read by the guest will return the value as set by the host. In
this way, the support to expose the feature to the guest is controlled by
the hypervisor.

Provide a new KVM capability that allows bits within MSRs to be recognized
as features. Two new ioctls are added to the /dev/kvm ioctl routine to
retrieve the list of these MSRs and then retrieve their values. A kvm_x86_ops
callback is used to determine support for the listed MSR-based features.

"The only core change is the fix for possible memory corruption by ALSA
ctl API since 4.14 kernel due to a thinko.
The rest are all device-specific: in addition to the usual suspects
(HD-audio and USB-audio fixups), a few LPE HDMI audio fixes came in at
this time"
