Guenter Roeck 148c847c9e hwmon: (max31790) Fix pwmX_enable attributes
pwmX_enable supports three possible values:

0: Fan control disabled. Duty cycle is fixed to 0%
1: Fan control enabled, pwm mode. Duty cycle is determined by
   values written into Target Duty Cycle registers.
2: Fan control enabled, rpm mode
   Duty cycle is adjusted such that fan speed matches
   the values in Target Count registers

The current code does not do this; instead, it mixes pwm control
configuration with fan speed monitoring configuration. Worse, it
reports that pwm control would be disabled (pwmX_enable==0) when
it is in fact enabled in pwm mode. Part of the problem may be that
the chip sets the "TACH input enable" bit on its own whenever the
mode bit is set to RPM mode, but that doesn't mean that "TACH input
enable" accurately reflects the pwm mode.

Fix it up and only handle pwm control with the pwmX_enable attributes.
In the documentation, clarify that disabling pwm control (pwmX_enable=0)
sets the pwm duty cycle to 0%. In the code, explain why TACH_INPUT_EN
is set together with RPM_MODE.

While at it, only update the configuration register if the configuration
has changed, and only update the cached configuration if updating the
chip configuration was successful.

Guenter Roeck 897f633989 hwmon: (max31790) Report correct current pwm duty cycles
The MAX31790 has two sets of registers for pwm duty cycles, one to request
a duty cycle and one to read the actual current duty cycle. Both do not
have to be the same.

When reporting the pwm duty cycle to the user, the actual pwm duty cycle
from pwm duty cycle registers needs to be reported. When setting it, the
pwm target duty cycle needs to be written. Since we don't know the actual
pwm duty cycle after a target pwm duty cycle has been written, set the
valid flag to false to indicate that actual pwm duty cycle should be read
from the chip instead of using cached values.

Irui Wang 5cd5760577 media: dt-bindings: media: mtk-vcodec: Add dma-ranges property
The mt8192 iommu support 0~16GB iova. We separate it to four banks:
0~4G; 4G~8G; 8G~12G; 12G~16G.

The "dma-ranges" could be used to adjust the bank we locate.
If we don't set this property. The default range always is 0~4G.

This is optional and only needed in mt8192, the dma ranges should
not cross 4G/8G/12G.

Here we don't have actual bus/parent concept here.  And the iova
requirement is for our HW. Thus put the property in our node.

Kees Cook 8669dbab2a mm/slub: clarify verification reporting
Patch series "Actually fix freelist pointer vs redzoning", v4.

This fixes redzoning vs the freelist pointer (both for middle-position
and very small caches).  Both are "theoretical" fixes, in that I see no
evidence of such small-sized caches actually be used in the kernel, but
that's no reason to let the bugs continue to exist, especially since
people doing local development keep tripping over it.  :)

This patch (of 3):

Instead of repeating "Redzone" and "Poison", clarify which sides of
those zones got tripped.  Additionally fix column alignment in the
trailer.

Before:

  BUG test (Tainted: G    B            ): Redzone overwritten
  ...
  Redzone (____ptrval____): bb bb bb bb bb bb bb bb      ........
  Object (____ptrval____): f6 f4 a5 40 1d e8            ...@..
  Redzone (____ptrval____): 1a aa                        ..
  Padding (____ptrval____): 00 00 00 00 00 00 00 00      ........

After:

  BUG test (Tainted: G    B            ): Right Redzone overwritten
  ...
  Redzone  (____ptrval____): bb bb bb bb bb bb bb bb      ........
  Object   (____ptrval____): f6 f4 a5 40 1d e8            ...@..
  Redzone  (____ptrval____): 1a aa                        ..
  Padding  (____ptrval____): 00 00 00 00 00 00 00 00      ........

The earlier commits that slowly resulted in the "Before" reporting were:

  d86bd1bece ("mm/slub: support left redzone")
  ffc79d2880 ("slub: use print_hex_dump")
  2492268472 ("SLUB: change error reporting format to follow lockdep loosely")

Rob Herring 1e9daaf616 dt-bindings: mmc: Clean-up examples to match documented bindings
The "sdhci" compatible is not documented though used as a fallback in a
few cases. It is also not supported by a Linux driver. Just remove the
example as part of ridding examples of undocumented bindings.

The "brcm,bcm43xx-fmac" compatible is also not documented. Update the
example to use one of the correct ones, "brcm,bcm4329-fmac", instead and
use a device class based nodename.

HS400 requires a data strobe line in addition to the usual MMC signal
lines. If a board design neglects to wire up this signal, HS400 mode is
not available, even if both the controller and the eMMC are claiming to
support this mode. Add a DT flag to allow boards to disable the HS400
support in this case.

Suman Anna 6a45d70cda dt-bindings: mmc: sdhci-am654: Remove duplicate ti,j721e-sdhci-4bit
The commit 7c7905df68 ("dt-bindings: mmc: sdhci-am654: fix compatible
for j7200") switched the compatible property from a regular enum to an
more appropriate combinatorial oneOf convention, and in the process has
introduced a duplicate ti,j721e-sdhci-4bit.

This generated the following warning on J721E boards that use the
ti,j721e-sdhci-4bit for two nodes:
 "mmc@4fb0000: compatible: More than one condition true in oneOf schema"
 "mmc@4f98000: compatible: More than one condition true in oneOf schema"

Remove the duplicate to fix this.

Linus Torvalds 43cb5d49a9 USB fixes for 5.13-rc6
Here are a number of tiny USB fixes for 5.13-rc6.
 
 There are more than I would normally like, but there's been a bunch of
 people banging on the gadget and dwc3 and typec code recently for I
 think an Android release, which has resulted in a number of small fixes.
 It's nice to see companies send fixes upstream for this type of work, a
 notable change from years ago.
 
 Anyway, fixes in here are:
 	- usb-serial device id updates
 	- usb-serial cp210x driver fixes for broken firmware versions
 	- typec fixes for crazy charging devices and other reported
 	  problems
 	- dwc3 fixes for reported problems found
 	- gadget fixes for reported problems
 	- tiny xhci fixes
 	- other small fixes for reported issues.
 	- revert of a problem fix found by linux-next testing
 
 All of these have passed 0-day and linux-next testing with no reported
 problems (the revert for the found linux-next build problem included).

Lai Jiangshan b1bd5cba33 KVM: X86: MMU: Use the correct inherited permissions to get shadow page
When computing the access permissions of a shadow page, use the effective
permissions of the walk up to that point, i.e. the logic AND of its parents'
permissions.  Two guest PxE entries that point at the same table gfn need to
be shadowed with different shadow pages if their parents' permissions are
different.  KVM currently uses the effective permissions of the last
non-leaf entry for all non-leaf entries.  Because all non-leaf SPTEs have
full ("uwx") permissions, and the effective permissions are recorded only
in role.access and merged into the leaves, this can lead to incorrect
reuse of a shadow page and eventually to a missing guest protection page
fault.

For example, here is a shared pagetable:

   pgd[]   pud[]        pmd[]            virtual address pointers
                     /->pmd1(u--)->pte1(uw-)->page1 <- ptr1 (u--)
        /->pud1(uw-)--->pmd2(uw-)->pte2(uw-)->page2 <- ptr2 (uw-)
   pgd-|           (shared pmd[] as above)
        \->pud2(u--)--->pmd1(u--)->pte1(uw-)->page1 <- ptr3 (u--)
                     \->pmd2(uw-)->pte2(uw-)->page2 <- ptr4 (u--)

  pud1 and pud2 point to the same pmd table, so:
  - ptr1 and ptr3 points to the same page.
  - ptr2 and ptr4 points to the same page.

(pud1 and pud2 here are pud entries, while pmd1 and pmd2 here are pmd entries)

- First, the guest reads from ptr1 first and KVM prepares a shadow
  page table with role.access=u--, from ptr1's pud1 and ptr1's pmd1.
  "u--" comes from the effective permissions of pgd, pud1 and
  pmd1, which are stored in pt->access.  "u--" is used also to get
  the pagetable for pud1, instead of "uw-".

- Then the guest writes to ptr2 and KVM reuses pud1 which is present.
  The hypervisor set up a shadow page for ptr2 with pt->access is "uw-"
  even though the pud1 pmd (because of the incorrect argument to
  kvm_mmu_get_page in the previous step) has role.access="u--".

- Then the guest reads from ptr3.  The hypervisor reuses pud1's
  shadow pmd for pud2, because both use "u--" for their permissions.
  Thus, the shadow pmd already includes entries for both pmd1 and pmd2.

- At last, the guest writes to ptr4.  This causes no vmexit or pagefault,
  because pud1's shadow page structures included an "uw-" page even though
  its role.access was "u--".

Any kind of shared pagetable might have the similar problem when in
virtual machine without TDP enabled if the permissions are different
from different ancestors.

In order to fix the problem, we change pt->access to be an array, and
any access in it will not include permissions ANDed from child ptes.

The test code is: https://lore.kernel.org/kvm/20210603050537.19605-1-jiangshanlai@gmail.com/
Remember to test it with TDP disabled.

The problem had existed long before the commit 41074d07c7 ("KVM: MMU:
Fix inherited permissions for emulated guest pte updates"), and it
is hard to find which is the culprit.  So there is no fixes tag here.

Roberto Sassu 88016de3ab ima: Define new template evm-sig
With the recent introduction of the evmsig template field, remote verifiers
can obtain the EVM portable signature instead of the IMA signature, to
verify file metadata.

After introducing the new fields to include file metadata in the
measurement list, this patch finally defines the evm-sig template, whose
format is:

d-ng|n-ng|evmsig|xattrnames|xattrlengths|xattrvalues|iuid|igid|imode

xattrnames, xattrlengths and xattrvalues are populated only from defined
EVM protected xattrs, i.e. the ones that EVM considers to verify the
portable signature. xattrnames and xattrlengths are populated only if the
xattr is present.

xattrnames and xattrlengths are not necessary for verifying the EVM
portable signature, but they are included for completeness of information,
if a remote verifier wants to infer more from file metadata.

Akira Yokosawa 0afd4df0d1 docs: pdfdocs: Prevent column squeezing by tabulary
Setting a reasonable width to \tymin prevents column squeezing
by tabulary.
Width of 20em works well in almost all the tables still in the
ascii-art format.

Excerpt from tabulary package documentation at [1]:

    To stop very narrow columns being too 'squeezed' by this process
    any columns that are narrower than \tymin are set to their natural
    width.

[1]: https://mirrors.ctan.org/macros/latex/contrib/tabulary/tabulary.pdf

Note: Sphinx has its own default value of \tymin set in
sphinxlatextables.sty (Sphinx 4.0.2) and sphinxmulticell.sty
(Sphinx 2.4.4) as follows:

    \setlength{\tymin}{3\fontcharwd\font`0 }

, which is not sufficient for kernel-doc.

Tested against Sphinx versions 2.4.4 and 4.0.2.

Roberto Sassu 026d7fc92a ima: Introduce template field evmsig and write to field sig as fallback
With the patch to accept EVM portable signatures when the
appraise_type=imasig requirement is specified in the policy, appraisal can
be successfully done even if the file does not have an IMA signature.

However, remote attestation would not see that a different signature type
was used, as only IMA signatures can be included in the measurement list.
This patch solves the issue by introducing the new template field 'evmsig'
to show EVM portable signatures and by including its value in the existing
field 'sig' if the IMA signature is not found.

The reason for kprobe::fault_handler(), as given by their comment:

 * We come here because instructions in the pre/post
 * handler caused the page_fault, this could happen
 * if handler tries to access user space by
 * copy_from_user(), get_user() etc. Let the
 * user-specified handler try to fix it first.

Is just plain bad. Those other handlers are ran from non-preemptible
context and had better use _nofault() functions. Also, there is no
upstream usage of this.

Mauro Carvalho Chehab 1e03fe2405 iio: ABI: sysfs-bus-iio: avoid a warning when doc is built
The description of those vars produce this warning:
  Documentation/ABI/testing/sysfs-bus-iio:799: WARNING: Inline emphasis start-string without end-string.

Due to an asterisk, which is the markup for emphasis. One possible
fix would be to use ``*_timeout`` to avoid it, but looking at
the descriptions of other fields in this file, a common pattern
is to refer to "these" when talking about the API calls that
are described.

So, change the text in order to preserve the meaning while
avoiding the need of using an asterisk there.

Akira Yokosawa f7ebe6b769 docs: Activate exCJK only in CJK chapters
Activating xeCJK in English and Italian-translation documents
results in sub-optimal typesetting with wide-looking apostrophes
and quotation marks.

The xeCJK package provides macros for enabling and disabling its
effect in the middle of a document, namely \makexeCJKactive and
\makexeCJKinactive.

So the goal of this change is to activate xeCJK in the relevant
chapters in translations.

To do this:

    o Define custom macros in the preamble depending on the
      availability of the "Noto Sans CJK" font so that those
      macros can be used regardless of the use of xeCJK package.

    o Patch \sphinxtableofcontents so that xeCJK is inactivated
      after table of contents.

    o Embed those custom macros in each language's index.rst file
      as a ".. raw:: latex" construct.

Note: A CJK chapter needs \kerneldocCJKon in front of its chapter
heading, while a non-CJK chapter should have \kerneldocCJKoff
below its chapter heading.

This is to make sure the CJK font is available to CJK chapter's
heading and ending page's footer.

Tested against Sphinx versions 2.4.4 and 4.0.2.

The v4l2-ctrls.c source has become much too big, so split it up
into four separate parts:

v4l2-ctrls-core.c: contains the core framework code
v4l2-ctrls-api.c: contains the uAPI interface to the framework
v4l2-ctrls-defs.c: contains the control definitions
v4l2-ctrls-request.c: contains the Request API helpers

And it adds a new v4l2-ctrls-priv.h.

No code was changed, but a number of checkpatch.pl warnings were
fixed (alignment, f == NULL -> !f, long comment block coding style,
unsigned -> unsigned int).

The copyright statements were updated as well since they were
quite out of date.

meaning they expect all the slices in a picture (either frame

These two are the only V4L2 MPEG-2 stateless decoders currently
supported. Given the VA-API drivers also work per-frame,
coalescing all the MPEG-2 slices in a buffer before the decoding
operation, it makes sense to not expect slice-mode drivers and
therefore remove V4L2_CID_MPEG_VIDEO_MPEG2_SLICE_PARAMS.

This is done to avoid carrying an unused interface. If needed,
this control can be added without breaking backwards compatibility.
Note that this would mean introducing a enumerator control to
specify the decoding mode (see V4L2_CID_STATELESS_H264_DECODE_MODE).

Ezequiel Garcia f329e21e9d media: uapi: mpeg2: Split sequence and picture parameters
Typically, bitstreams are composed of a sequence header,
followed by a number of picture header and picture coding extension
headers. Each picture can be composed of a number of slices.

Let's split the MPEG-2 uAPI to follow these semantics more closely,
allowing more usage flexibility. Having these controls split up
allows applications to set a sequence control at the beginning
of a sequence, and then set a picture control for each frame.

While here add padding fields where needed, and document
the uAPI header thoroughly.

Note that the V4L2_CTRL_TYPE_{} defines had to be moved because
it clashes with existing ones. This is not really an issue
since they will be re-defined when the controls are moved
out of staging.

Ezequiel Garcia 81bbb65f19 media: uapi: mpeg2: rework quantisation matrices semantics
As stated in the MPEG-2 specification, section 6.3.7 "Quant matrix
extension":

  Each quantisation matrix has a default set of values. When a
  sequence_header_code is decoded all matrices shall be reset to
  their default values. User defined matrices may be downloaded
  and this can occur in a sequence_header() or in a
  quant_matrix_extension().

The load_intra_quantiser_matrix syntax elements are transmitted
in the bitstream headers, signalling that a quantisation matrix
needs to be loaded and used for pictures transmitted afterwards
(until the matrices are reset).

This "load" semantics are implemented in the V4L2 interface
without the need of any "load" flags: passing the control
is effectively a load.

Therefore, rework the V4L2_CID_MPEG_VIDEO_MPEG2_QUANTISATION
semantics to match the MPEG-2 semantics. Quantisation matrices
values are now initialized by the V4L2 control core to their
reset default value, and applications are expected to reset
their values as specified.

The quantisation control is therefore optional, and used to
load bitstream-defined values in the quantisation matrices.

Roberto Sassu 9acc89d31f evm: Refuse EVM_ALLOW_METADATA_WRITES only if an HMAC key is loaded
EVM_ALLOW_METADATA_WRITES is an EVM initialization flag that can be set to
temporarily disable metadata verification until all xattrs/attrs necessary
to verify an EVM portable signature are copied to the file. This flag is
cleared when EVM is initialized with an HMAC key, to avoid that the HMAC is
calculated on unverified xattrs/attrs.

Currently EVM unnecessarily denies setting this flag if EVM is initialized
with a public key, which is not a concern as it cannot be used to trust
xattrs/attrs updates. This patch removes this limitation.

include/linux/bits.h in commit 8bd9cb51da ("locking/atomics, asm-generic:
Move some macros from <linux/bitops.h> to a new <linux/bits.h> file").

Since that commit BIT() has moved again into include/vdso/bits.h via
commit 3945ff37d2 ("linux/bits.h: Extract common header for vDSO").

I think the move to the vDSO header can be considered an implementation
detail, so for now update the checkpatch documentation to recommend use
of include/linux/bits.h.

Mauro Carvalho Chehab 0a5fab9f08 docs: virt: api.rst: fix a pointer to SGX documentation
