Quoting from mt8183 datasheet, the number of transfers to be
transferred in one transaction should be set to bigger than 1,
so we should forbid zero-length transfer and update functionality.

The driver does not support the SMBUS Quick command so remove the
flag that indicates that level of support.
By default the i2c_detect tool uses the quick command to try and
detect devices at some bus addresses. If the quick command is used
then we will not detect the device, even though it is present.

When counting dispatched micro-ops with cnt_ctl=1, in order to prevent
sample bias, IBS hardware preloads the least significant 7 bits of
current count (IbsOpCurCnt) with random values, such that, after the
interrupt is handled and counting resumes, the next sample taken
will be slightly perturbed.
The current count bitfield is in the IBS execution control h/w register,
alongside the maximum count field.
Currently, the IBS driver writes that register with the maximum count,
leaving zeroes to fill the current count field, thereby overwriting
the random bits the hardware preloaded for itself.
Fix the driver to actually retain and carry those random bits from the
read of the IBS control register, through to its write, instead of
overwriting the lower current count bits with zeroes.
Tested with:
perf record -c 100001 -e ibs_op/cnt_ctl=1/pp -a -C 0 taskset -c 0 <workload>

Tested on Family 15h and 17h machines.
Machines prior to family 10h Rev. C don't have the RDWROPCNT capability,
and have the IbsOpCurCnt bitfield reserved, so this patch shouldn't
affect their operation.
It is unknown why commit db98c5faf8 ("perf/x86: Implement 64-bit
counter support for IBS") ignored the lower 4 bits of the IbsOpCurCnt
field; the number of preloaded random bits has always been 7, AFAICT.

The recent change to shuffle the codec initialization procedure for
Realtek via commit 607ca3bd22 ("ALSA: hda/realtek - EAPD turn on
later") caused the silent output on some machines. This change was
supposed to be safe, but it isn't actually; some devices have quirk
setups to override the EAPD via COEF or BTL in the additional verb
table, which is applied at the beginning of snd_hda_gen_init(). And
this EAPD setup is again overridden in alc_auto_init_amp().
For recovering from the regression, tell snd_hda_gen_init() not to
apply the verbs there by a new flag, then apply the verbs in
alc_init().

The named modes support has introduced a number of glitches that were in
part due to the fact that the parser will take any string as a named mode.
Since we shouldn't have a lot of options there (and they should be pretty
standard), let's introduce a whitelist of the available named modes so that
the kernel can differentiate between a poorly formed command line and a
named mode.

The command line parser when it has been rewritten introduced a regression
when the only thing on the command line is an option to force the detection
of a connector (such as video=HDMI-A-1:d), which are completely valid.
It's been further broken by the support for the named modes which take
anything that is not a resolution as a named mode.
Let's fix this by running the extra command line option parser on the named
modes if they only take a single character.

The IP datasheet says this controller is compatible with SD Host
Specification Version v4.00.
As it turned out, the ADMA of this IP does not work with 64-bit mode
when it is in the Version 3.00 compatible mode; it understands the
old 64-bit descriptor table (as defined in SDHCI v2), but the ADMA
System Address Register (SDHCI_ADMA_ADDRESS) cannot point to the
64-bit address.
I noticed this issue only after commit bd2e75633c ("dma-contiguous:
use fallback alloc_pages for single pages"). Prior to that commit,
dma_set_mask_and_coherent() returned the dma address that fits in
32-bit range, at least for the default arm64 configuration
(arch/arm64/configs/defconfig). Now the host->adma_addr exceeds the
32-bit limit, causing the real problem for the Socionext SoCs.
(As a side-note, I was also able to reproduce the issue for older
kernels by turning off CONFIG_DMA_CMA.)

The OCR register defines the supported range of VDD voltages for SD cards.
However, it has turned out that some SD cards reports an invalid voltage
range, for example having bit7 set.
When a host supports MMC_CAP2_FULL_PWR_CYCLE and some of the voltages from
the invalid VDD range, this triggers the core to run a power cycle of the
card to try to initialize it at the lowest common supported voltage.
Obviously this fails, since the card can't support it.
Let's fix this problem, by clearing invalid bits from the read OCR register
for SD cards, before proceeding with the VDD voltage negotiation.

Family 16h Model 30h SMBus controller needs the same port selection fix

The Hudson2 PCI Device ID (PCI_DEVICE_ID_AMD_HUDSON2_SMBUS) is shared

ftrace does not use text_poke() for enabling trace functionality. It uses
its own mechanism and flips the whole kernel text to RW and back to RO.
The CPA rework removed a loop based check of 4k pages which tried to
preserve a large page by checking each 4k page whether the change would
actually cover all pages in the large page.
This resulted in endless loops for nothing as in testing it turned out that
it actually never preserved anything. Of course testing missed to include
ftrace, which is the one and only case which benefitted from the 4k loop.
As a consequence enabling function tracing or ftrace based kprobes results
in a full 4k split of the kernel text, which affects iTLB performance.
The kernel RO protection is the only valid case where this can actually
preserve large pages.
All other static protections (RO data, data NX, PCI, BIOS) are truly
static. So a conflict with those protections which results in a split
should only ever happen when a change of memory next to a protected region
is attempted. But these conflicts are rightfully splitting the large page
to preserve the protected regions. In fact a change to the protected
regions itself is a bug and is warned about.
Add an exception for the static protection check for kernel text RO when
the to be changed region spawns a full large page which allows to preserve
the large mappings. This also prevents the syslog to be spammed about CPA
violations when ftrace is used.
The exception needs to be removed once ftrace switched over to text_poke()
which avoids the whole issue.

The move of the IXP4xx SoC drivers exposed their config options on all

Fix this by wrapping them inside an ARCH_IXP4XX or COMPILE_TEST block.

In ieee80211_deliver_skb_to_local_stack intercepts EAPoL frames if
mac80211 is configured to do so and forwards the contents over nl80211.
During this process some additional data is also forwarded, including
whether the frame was received encrypted or not. Unfortunately just
prior to the call to ieee80211_deliver_skb_to_local_stack, skb->cb is
cleared, resulting in incorrect data being exposed over nl80211.

We need to use a different firmware for C0 versions of killer Qu NICs.
Add structures for them and handle them in the if block that detects
C0 revisions.
Additionally, instead of having an inclusive check for QnJ devices,
make the selection exclusive, so that switching to QnJ is the
exception, not the default. This prevents us from having to add all
the non-QnJ cards to an exclusion list. To do so, only go into the
QnJ block if the device has an RF ID type HR and HW revision QnJ.

Since the chained quirks via chained_before flag is applied before the

A similar workaround for the suspend/resume problem is needed for yet
another ASUS machines, P6X models. Like the previous fix, the BIOS

nfp: flower: fix bugs in merge tunnel encap code
John says:
There are few bugs in the merge encap code that have come to light with
recent driver changes. Effectively, flow bind callbacks were being
registered twice when using internal ports (new 'busy' code triggers
this). There was also an issue with neighbour notifier messages being
ignored for internal ports.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
Recent code changes to NFP allowed the offload of neighbour entries to FW
when the next hop device was an internal port. This allows for offload of
tunnel encap when the end-point IP address is applied to such a port.
Unfortunately, the neighbour event handler still rejects events that are
not associated with a repr dev and so the firmware neighbour table may get
out of sync for internal ports.
Fix this by allowing internal port neighbour events to be correctly
processed.

Internal port TC offload is implemented through user-space applications
(such as OvS) by adding filters at egress via TC clsact qdiscs. Indirect
block offload support in the NFP driver accepts both ingress qdisc binds
and egress binds if the device is an internal port. However, clsact sends
bind notification for both ingress and egress block binds which can lead
to the driver registering multiple callbacks and receiving multiple
notifications of new filters.
Fix this by rejecting ingress block bind callbacks when the port is
internal and only adding filter callbacks for egress binds.

This reverts commit 0ee1f47349.
The commit 0ee1f47349 ("r8152: napi hangup fix after
disconnect") adds a check about RTL8152_UNPLUG to determine
if calling napi_disable() is invalid in rtl8152_close(),
when rtl8152_disconnect() is called. This avoids to use
napi_disable() after calling netif_napi_del().
Howver, commit ffa9fec30c ("r8152: set RTL8152_UNPLUG
only for real disconnection") causes that RTL8152_UNPLUG
is not always set when calling rtl8152_disconnect().
Therefore, I have to revert commit 0ee1f47349 ("r8152:
napi hangup fix after disconnect"), first. And submit
another patch to fix it.
