Start a new Japanese translation of
Documentation/process/submitting-patches.rst.
Instead of moving the outdated 2011
translation (SubmittingPatches), we are starting a fresh translation of
the current English document.
This patch adds the initial file structure, the warning about the
document being under construction, and the translation of the
introduction section.
The translation work will be done incrementally.

Introduce a new command for KVM_MEMORY_ENCRYPT_OP ioctl that can be used
to enable fetching of endorsement key certificates from userspace via
the new KVM_EXIT_SNP_REQ_CERTS exit type. Also introduce a new
KVM_X86_SEV_SNP_REQ_CERTS KVM device attribute so that userspace can
query whether the kernel supports the new command/exit.

For SEV-SNP, the host can optionally provide a certificate table to the
guest when it issues an attestation request to firmware (see GHCB 2.0
specification regarding "SNP Extended Guest Requests"). This certificate
table can then be used to verify the endorsement key used by firmware to
sign the attestation report.
While it is possible for guests to obtain the certificates through other
means, handling it via the host provides more flexibility in being able
to keep the certificate data in sync with the endorsement key throughout
host-side operations that might resulting in the endorsement key
changing.
In the case of KVM, userspace will be responsible for fetching the
certificate table and keeping it in sync with any modifications to the
endorsement key by other userspace management tools. Define a new
KVM_EXIT_SNP_REQ_CERTS event where userspace is provided with the GPA of
the buffer the guest has provided as part of the attestation request so
that userspace can write the certificate data into it while relying on
filesystem-based locking to keep the certificates up-to-date relative to
the endorsement keys installed/utilized by firmware at the time the
certificates are fetched.
[Melody: Update the documentation scheme about how file locking is
expected to happen.]

As comments mentioned this is old (and actually deprecated) interface
to set custom baud rates. This interface has limitations as it only
allows to set a single opaque value called "custom_divisor". If the HW
needs more complex settings (like fractional divisor) it must somehow
encode this. This is horrid interface that is very driver specific
and not flexible. Meanwhile Linux has established way to set free
baud rate settings via BOTHER [1]. With all this being said, remove
deprecated interface for good.

This patch introduces a priority sysfs attribute to the USB Type-C
alternate mode port interface. This new attribute allows user-space to
configure the numeric priority of alternate modes managing their preferred
order of operation. If a new priority value conflicts with an existing
mode's priority, the priorities of the conflicting mode and all subsequent
modes are automatically incremented to ensure uniqueness.

When software issues a Cache Maintenance Operation (CMO) targeting a
dirty cache line, the CPU and DSU cluster may optimize the operation by
combining the CopyBack Write and CMO into a single combined CopyBack
Write plus CMO transaction presented to the interconnect (MCN).
For these combined transactions, the MCN splits the operation into two
separate transactions, one Write and one CMO, and then propagates the
write and optionally the CMO to the downstream memory system or external
Point of Serialization (PoS).
However, the MCN may return an early CompCMO response to the DSU cluster
before the corresponding Write and CMO transactions have completed at
the external PoS or downstream memory. As a result, stale data may be
observed by external observers that are directly connected to the
external PoS or downstream memory.
This erratum affects any system topology in which the following
conditions apply:
- The Point of Serialization (PoS) is located downstream of the
interconnect.
- A downstream observer accesses memory directly, bypassing the
interconnect.
Conditions:
This erratum occurs only when all of the following conditions are met:
1. Software executes a data cache maintenance operation, specifically,
a clean or clean&invalidate by virtual address (DC CVAC or DC
CIVAC), that hits on unique dirty data in the CPU or DSU cache.
This results in a combined CopyBack and CMO being issued to the
interconnect.
2. The interconnect splits the combined transaction into separate Write
and CMO transactions and returns an early completion response to the
CPU or DSU before the write has completed at the downstream memory
or PoS.
3. A downstream observer accesses the affected memory address after the
early completion response is issued but before the actual memory
write has completed. This allows the observer to read stale data
that has not yet been updated at the PoS or downstream memory.
The implementation of workaround put a second loop of CMOs at the same
virtual address whose operation meet erratum conditions to wait until
cache data be cleaned to PoC. This way of implementation mitigates
performance penalty compared to purely duplicate original CMO.

Currently, reading files with different paths (or names) but the same
content will consume multiple copies of the page cache, even if the
content of these page caches is the same. For example, reading
identical files (e.g., *.so files) from two different minor versions of
container images will cost multiple copies of the same page cache,
since different containers have different mount points. Therefore,
sharing the page cache for files with the same content can save memory.
This introduces the page cache share feature in erofs. It allocate a
shared inode and use its page cache as shared. Reads for files
with identical content will ultimately be routed to the page cache of
the shared inode. In this way, a single page cache satisfies
multiple read requests for different files with the same contents.
We introduce new mount option `inode_share` to enable the page
sharing mode during mounting. This option is used in conjunction
with `domain_id` to share the page cache within the same trusted
domain.

Add the devicetree binding for PCIe M.2 Mechanical Key M connector defined
in the PCI Express M.2 Specification, r4.0, sec 5.3. This connector
provides interfaces like PCIe and SATA to attach the Solid State Drives
(SSDs) to the host machine along with additional interfaces like USB, and
SMBus for debugging and supplementary features.
The connector provides a primary power supply of 3.3v, along with an
optional 1.8v VIO supply for the Adapter I/O buffer circuitry operating at
1.8v sideband signaling.
The connector also supplies optional signals in the form of GPIOs for fine
grained power management.

The PCIESYS register space contains a pure clock controller, which
has no system controller register, so this definitely doesn't need

As a side note, luckily no devicetree ever added the syscon string

a dtbs_check warning for mt7622.

Document the `directio` mount option for file-backed mounts, because
recent users need this and this mount option has been available since
commit 6422cde1b0d5 ("erofs: use buffered I/O for file-backed mounts
by default") without proper documentation.

- Get rid of `sbi->opt.max_sync_decompress_pages` since it's fixed as
3 all the time;
- Add Z_EROFS_MAX_SYNC_DECOMPRESS_BYTES in bytes instead of in pages,
since for non-4K pages, 3-page limitation makes no sense;
- Move `sync_decompress` to sbi to avoid unexpected remount impact;
- Fold z_erofs_is_sync_decompress() into its caller;
- Better description of sysfs entry `sync_decompress`.

The platform initialisation code for the AST2600 implements the custom
SMP bringup protocol, and searches for the relevant compatible. As a
consequence, define the requisite node and the compatible string, which
in-turn tidies up the dtb check results.

Commit a95419ff9f21 ("dt-bindings: mfd: syscon: Add mt7981-topmisc")
added the mediatek,mt7981-topmisc compatible to the `select` block
which is used only for compatibility with older dtschema, but did
not add it in the actual block allowing to specify the "syscon"
fallback compatible, which is required for such node to do anything
meaningful in the end.
Add the mediatek,mt7981-topmisc compatible in the right list to
allow specifing compatible = "mediatek,mt7981-topmisc", "syscon"
in the relevant devicetree node.

The NXP S32 SoCs have a GPR region which is used by a variety of
drivers. Some examples of the registers in this region are:
* DDR_PMU_IRQ
* GMAC0_PHY_INTF_SEL
* GMAC1_PHY_INTF_SEL
* PFE_EMACS_INTF_SEL
* PFE_COH_EN
* PFE_PWR_CTRL
* PFE_EMACS_GENCTRL1
* PFE_GENCTRL3
Use the syscon interface to access these registers.
