The mic has lots of noises if mic boost is enabled. So disable mic boost
to get crystal clear audio capture.

Fix for omap gpt12 timer error handling
Two of the recent fixes for ti-sysc driver had bad interaction for a
function return value that caused one of the fixes to not work so we
need to change the return value handling. Otherwise early beagleboard
variants still have a boot issue.

Two legacy PCI sysfs objects "legacy_io" and "legacy_mem" were updated
to use an unified address space in the commit 636b21b50152 ("PCI: Revoke
mappings like devmem"). This allows for revocations to be managed from
a single place when drivers want to take over and mmap() a /dev/mem
range.
Following the update, both of the sysfs objects should leverage the
iomem_get_mapping() function to get an appropriate address range, but
only the "legacy_io" has been correctly updated - the second attribute
seems to be using a wrong variable to pass the iomem_get_mapping()
function to.
Thus, correct the variable name used so that the "legacy_mem" sysfs
object would also correctly call the iomem_get_mapping() function.

The Renoir XHCI controller apparently doesn't resume reliably with the
standard D3hot-to-D0 delay. Increase it to 20ms.
[Alex: I talked to the AMD USB hardware team and the AMD Windows team and
they are not aware of any HW errata or specific issues. The HW works fine
in Windows. I was told Windows uses a rather generous default delay of
100ms for PCI state transitions.]

====================
mptcp: Bug fixes
Here are two bug fixes for the net tree:
Patch 1 fixes a memory leak that could be encountered when clearing the
list of advertised MPTCP addresses.
Patch 2 fixes a protocol issue early in an MPTCP connection, to ensure
both peers correctly understand that the full MPTCP connection handshake
has completed even when the server side quickly sends an ADD_ADDR
option.

If directly after an MP_CAPABLE 3WHS, the client receives an ADD_ADDR
with HMAC from the server, it is enough to switch to a "fully
established" mode because it has received more MPTCP options.
It was then OK to enable the "fully_established" flag on the MPTCP
socket. Still, best to check if the ADD_ADDR looks valid by looking if
it contains an HMAC (no 'echo' bit). If an ADD_ADDR echo is received
while we are not in "fully established" mode, it is strange and then
we should not switch to this mode now.
But that is not enough. On one hand, the path-manager has be notified
the state has changed. On the other hand, the "fully_established" flag
on the subflow socket should be turned on as well not to re-send the
MP_CAPABLE 3rd ACK content with the next ACK.

In __init_el2_timers we initialize CNTHCTL_EL2.{EL1PCEN,EL1PCTEN} with a
RMW sequence, leaving all other bits UNKNOWN.
In general, we should initialize all bits in a register rather than
using an RMW sequence, since most bits are UNKNOWN out of reset, and as
new bits are added to the reigster their reset value might not result in
expected behaviour.
In the case of CNTHCTL_EL2, FEAT_ECV added a number of new control bits
in previously RES0 bits, which reset to UNKNOWN values, and may cause
issues for EL1 and EL0:
* CNTHCTL_EL2.ECV enables the CNTPOFF_EL2 offset (which itself resets to
an UNKNOWN value) at EL0 and EL1. Since the offset could reset to
distinct values across CPUs, when the control bit resets to 1 this
could break timekeeping generally.
* CNTHCTL_EL2.{EL1TVT,EL1TVCT} trap EL0 and EL1 accesses to the EL1
virtual timer/counter registers to EL2. When reset to 1, this could
cause unexpected traps to EL2.
Initializing these bits to zero avoids these problems, and all other
bits in CNTHCTL_EL2 other than EL1PCEN and EL1PCTEN can safely be reset
to zero.
This patch ensures we initialize CNTHCTL_EL2 accordingly, only setting
EL1PCEN and EL1PCTEN, and setting all other bits to zero.

When scsi_dispatch_cmd was moved to scsi_lib.c and made static, some
compilers (i.e., at least gcc 8.4.0) decided to compile this
inline. This is a problem for lkdtm.ko, which inserted a kprobe
on this function for the SCSI_DISPATCH_CMD crashpoint.
Move this crashpoint one function up the call chain to
scsi_queue_rq. Though this is also a static function, it should never be
inlined because it is assigned as a structure entry. Therefore,
kprobe_register should always be able to find it.

Jordan, Fabiano & Murilo were able to reproduce and identify that the
problem is caused by the call to module_enable_ro() in do_init_module(),
which happens after the module's init function has already been called.
Our current implementation of change_page_attr() is not safe against
concurrent accesses, because it invalidates the PTE before flushing the
TLB and then installing the new PTE. That leaves a window in time where
there is no valid PTE for the page, if another CPU tries to access the
page at that time we see something like the fault above.
We can't simply switch to set_pte_at()/flush TLB, because our hash MMU
code doesn't handle a set_pte_at() of a valid PTE. See [1].
But we do have pte_update(), which replaces the old PTE with the new,
meaning there's no window where the PTE is invalid. And the hash MMU
version hash__pte_update() deals with synchronising the hash page table
correctly.

Commit b5efec00b671 ("powerpc/32s: Move KUEP locking/unlocking in C")
removed the 'isync' instruction after adding/removing NX bit in user
segments. The reasoning behind this change was that when setting the
NX bit we don't mind it taking effect with delay as the kernel never
executes text from userspace, and when clearing the NX bit this is
to return to userspace and then the 'rfi' should synchronise the
context.
However, it looks like on book3s/32 having a hash page table, at least
on the G3 processor, we get an unexpected fault from userspace, then
this is followed by something wrong in the verification of MSR_PR
at end of another interrupt.
This is fixed by adding back the removed isync() following update
of NX bit in user segment registers. Only do it for cores with an
hash table, as 603 cores don't exhibit that problem and the two isync
increase ./null_syscall selftest by 6 cycles on an MPC 832x.

Function "dma_map_sg" is entitled to merge adjacent entries
and return a value smaller than what was passed as "nents".
Subsequently "ib_map_mr_sg" needs to work with this value ("sg_dma_len")
rather than the original "nents" parameter ("sg_len").
This old RDS bug was exposed and reliably causes kernel panics

Currently we are unable to ping a bridge on top of a felix switch which
uses the ocelot-8021q tagger. The packets are dropped on the ingress of
the user port and the 'drop_local' counter increments (the counter which
denotes drops due to no valid destinations).
Dumping the PGID tables, it becomes clear that the PGID_SRC of the user
port is zero, so it has no valid destinations.
But looking at the code, the cpu_fwd_mask (the bit mask of DSA tag_8021q
ports) is clearly missing from the forwarding mask of ports that are
under a bridge. So this has always been broken.
Looking at the version history of the patch, in v7
https://patchwork.kernel.org/project/netdevbpf/patch/20210125220333.1004365-12-olteanv@gmail.com/
the code looked like this:
/* Standalone ports forward only to DSA tag_8021q CPU ports */
unsigned long mask = cpu_fwd_mask;
(...)
} else if (ocelot->bridge_fwd_mask & BIT(port)) {
mask |= ocelot->bridge_fwd_mask & ~BIT(port);
while in v8 (the merged version)
https://patchwork.kernel.org/project/netdevbpf/patch/20210129010009.3959398-12-olteanv@gmail.com/
it looked like this:
unsigned long mask;
(...)
} else if (ocelot->bridge_fwd_mask & BIT(port)) {
mask = ocelot->bridge_fwd_mask & ~BIT(port);
So the breakage was introduced between v7 and v8 of the patch.

Preload set of configurations.
This patch creates a small set of preloaded configurations and features
that are available immediately after coresight has been initialised.
The current set provides a strobing feature for ETMv4, that creates a
periodic sampling of trace by switching trace generation on and off
using counters in the ETM.
A configuration called "autofdo" is also provided that uses the 'strobing'
feature and provides a couple of preset values, selectable on the perf
command line.

Creates an system management API to allow complex configurations and
features to be programmed into a CoreSight infrastructure.
A feature is defined as a programming set for a device or class of
devices.
A configuration is a set of features across the system that are enabled
for a trace session.
The API will manage system wide configuration, and allow complex
programmed features to be added to individual device instances, and
provide for system wide configuration selection on trace capture
operations.
This patch creates the initial data object and the initial API for
loading configurations and features.

I had forgotten just how sensitive hackbench is to extra pipe wakeups,
and commit 3a34b13a88ca ("pipe: make pipe writes always wake up
readers") ended up causing a quite noticeable regression on larger
machines.
Now, hackbench isn't necessarily a hugely meaningful benchmark, and it's
not clear that this matters in real life all that much, but as Mel
points out, it's used often enough when comparing kernels and so the
performance regression shows up like a sore thumb.
It's easy enough to fix at least for the common cases where pipes are
used purely for data transfer, and you never have any exciting poll
usage at all. So set a special 'poll_usage' flag when there is polling
activity, and make the ugly "EPOLLET has crazy legacy expectations"
semantics explicit to only that case.
I would love to limit it to just the broken EPOLLET case, but the pipe
code can't see the difference between epoll and regular select/poll, so
any non-read/write waiting will trigger the extra wakeup behavior. That
is sufficient for at least the hackbench case.
Apart from making the odd extra wakeup cases more explicitly about
EPOLLET, this also makes the extra wakeup be at the _end_ of the pipe
write, not at the first write chunk. That is actually much saner
semantics (as much as you can call any of the legacy edge-triggered
expectations for EPOLLET "sane") since it means that you know the wakeup
will happen once the write is done, rather than possibly in the middle
of one.
[ For stable people: I'm putting a "Fixes" tag on this, but I leave it
up to you to decide whether you actually want to backport it or not.
It likely has no impact outside of synthetic benchmarks - Linus ]

Commit a20dcf53ea98 ("usb: typec: tcpm: Respond Not_Supported if no
snk_vdo"), stops tcpm_pd_data_request() calling tcpm_handle_vdm_request()
when port->nr_snk_vdo is not set. But the VDM might be intended for an
altmode-driver, in which case nr_snk_vdo does not matter.
This change breaks the forwarding of connector hotplug (HPD) events
for displayport altmode on devices which don't set nr_snk_vdo.
tcpm_pd_data_request() is the only caller of tcpm_handle_vdm_request(),
so we can move the nr_snk_vdo check to inside it, at which point we
have already looked up the altmode device so we can check for this too.
Doing this check here also ensures that vdm_state gets set to
VDM_STATE_DONE if it was VDM_STATE_BUSY, even if we end up with
responding with PD_MSG_CTRL_NOT_SUPP later.
Note that tcpm_handle_vdm_request() was already sending
PD_MSG_CTRL_NOT_SUPP in some circumstances, after moving the nr_snk_vdo
check the same error-path is now taken when that check fails. So that
we have only one error-path for this and not two. Replace the
tcpm_queue_message(PD_MSG_CTRL_NOT_SUPP) used by the existing error-path
with the more robust tcpm_pd_handle_msg() from the (now removed) second
error-path.

When a PASID was used as nested mode, released and reused, the following
error message will appear:
[ 180.187556] Unexpected page request in Privilege Mode
[ 180.187565] Unexpected page request in Privilege Mode
[ 180.279933] Unexpected page request in Privilege Mode
[ 180.279937] Unexpected page request in Privilege Mode
Per chapter 6.5.3.3 of VT-d spec 3.3, when tear down a pasid entry, the
software should use Domain selective IOTLB flush if the PGTT of the pasid
entry is SL only or Nested, while for the pasid entries whose PGTT is FL
only or PT using PASID-based IOTLB flush is enough.

A PASID reference is increased whenever a device is bound to an mm (and
its PASID) successfully (i.e. the device's sdev user count is increased).
But the reference is not dropped every time the device is unbound
successfully from the mm (i.e. the device's sdev user count is decreased).
The reference is dropped only once by calling intel_svm_free_pasid() when
there isn't any device bound to the mm. intel_svm_free_pasid() drops the
reference and only frees the PASID on zero reference.
Fix the issue by dropping the PASID reference and freeing the PASID when
no reference on successful unbinding the device by calling
intel_svm_free_pasid() .

Syzbot reported uninit-value in asix_mdio_read(). The problem was in
missing error handling. asix_read_cmd() should initialize passed stack
variable smsr, but it can fail in some cases. Then while condidition
checks possibly uninit smsr variable.
Since smsr is uninitialized stack variable, driver can misbehave,
because smsr will be random in case of asix_read_cmd() failure.
Fix it by adding error handling and just continue the loop instead of
checking uninit value.
Added helper function for checking Host_En bit, since wrong loop was used
in 4 functions and there is no need in copy-pasting code parts.

fq qdisc requires tstamp to be cleared in the forwarding path. Now ovs
doesn't clear skb->tstamp. We encountered a problem with linux
version 5.4.56 and ovs version 2.14.1, and packets failed to
dequeue from qdisc when fq qdisc was attached to ovs port.
