In register_ftrace_function_probe(), we are not checking the return
value of alloc_and_copy_ftrace_hash(). The subsequent call to
ftrace_match_records() may end up dereferencing the same. Add a check to
ensure this doesn't happen.

The race between adding a function probe and reading the probes that exist
is very subtle. It needs a comment. Also, the issue can also happen if the
probe has has the EMPTY_HASH as its func_hash.

The test (ftrace_set_ftrace_filter.sh) is part of ftrace stress tests
and the crash happens when the test does 'cat
$TRACING_PATH/set_ftrace_filter'.
The address points to the second line below, in t_probe_next(), where
filter_hash is dereferenced:
hash = iter->probe->ops.func_hash->filter_hash;
size = 1 << hash->size_bits;
This happens due to a race with register_ftrace_function_probe(). A new
ftrace_func_probe is created and added into the func_probes list in
trace_array under ftrace_lock. However, before initializing the filter,
we drop ftrace_lock, and re-acquire it after acquiring regex_lock. If
another process is trying to read set_ftrace_filter, it will be able to
acquire ftrace_lock during this window and it will end up seeing a NULL
filter_hash.
Fix this by just checking for a NULL filter_hash in t_probe_next(). If
the filter_hash is NULL, then this probe is just being added and we can
simply return from here.

This reverts commit 557529494d.
Commit 557529494d ("iommu/vt-d: Avoid duplicated pci dma alias
consideration") aimed to address a NULL pointer deference issue
happened when a thunderbolt device driver returned unexpectedly.
Unfortunately, this change breaks a previous pci quirk added by
commit cc346a4714 ("PCI: Add function 1 DMA alias quirk for
Marvell devices"), as the result, devices like Marvell 88SE9128
SATA controller doesn't work anymore.
We will continue to try to find the real culprit mentioned in
557529494d, but for now we should revert it to fix current
breakage.

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.)
Call sdhci_enable_v4_mode() to fix this.

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
as described and fixed in commit 0fe16195f8 ("i2c: piix4: Fix SMBus port
selection for AMD Family 17h chips")
commit 6befa3fde6 ("i2c: piix4: Support alternative port selection
register") also fixed the port selection for Hudson2, but unfortunately
this is not the exact same device and the AMD naming and PCI Device IDs
aren't particularly helpful here.
The SMBus port selection register is common to the following Families
and models, as documented in AMD's publicly available BIOS and Kernel
Developer Guides:
50742 - Family 15h Model 60h-6Fh (PCI_DEVICE_ID_AMD_KERNCZ_SMBUS)
55072 - Family 15h Model 70h-7Fh (PCI_DEVICE_ID_AMD_KERNCZ_SMBUS)
52740 - Family 16h Model 30h-3Fh (PCI_DEVICE_ID_AMD_HUDSON2_SMBUS)
The Hudson2 PCI Device ID (PCI_DEVICE_ID_AMD_HUDSON2_SMBUS) is shared
between Bolton FCH and Family 16h Model 30h, but the location of the
SmBus0Sel port selection bits are different:
51192 - Bolton Register Reference Guide
We distinguish between Bolton and Family 16h Model 30h using the PCI
Revision ID:
Bolton is device 0x780b, revision 0x15
Family 16h Model 30h is device 0x780b, revision 0x1F
Family 15h Model 60h and 70h are both device 0x790b, revision 0x4A.
The following additional public AMD BKDG documents were checked and do
not share the same port selection register:
42301 - Family 15h Model 00h-0Fh doesn't mention any
42300 - Family 15h Model 10h-1Fh doesn't mention any
49125 - Family 15h Model 30h-3Fh doesn't mention any

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

The noencrypt flag was intended to be set if the "frame was received
unencrypted" according to include/uapi/linux/nl80211.h. However, the
current behavior is opposite of this.

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.
