Commit 3f1b0e1f28 (".gitignore update") added *.orig and *.rej
patterns to .gitignore in v2.6.23. The commit message didn't give a
rationale. Later on, commit 1f5d3a6b65 ("Remove *.rej pattern from
.gitignore") removed the *.rej pattern in v2.6.26, on the rationale that
*.rej files indicated something went really wrong and should not be
ignored.
The *.rej files are now shown by `git status`, which helps located
conflicts when applying patches and lowers the probability that they
will go unnoticed. It is however still easy to overlook the *.orig files
which slowly polute the source tree. That's not as big of a deal as not
noticing a conflict, but it's still not nice.
Drop the *.orig pattern from .gitignore to avoid this and help keep the

[masahiroy@kernel.org:
I do not have a strong opinion about this. Perhaps some people may have
a different opinion.
If you are someone who wants to ignore *.orig, it is likely you would
want to do so across all projects. Then, $XDG_CONFIG_HOME/git/ignore
would be more suitable for your needs. gitignore(5) suggests, "Patterns
which a user wants Git to ignore in all situations generally go into a
file specified by core.excludesFile in the user's ~/.gitconfig".
Please note that you cannot do the opposite; if *.orig is ignored by
the project's .gitignore, you cannot override the decision because
$XDG_CONFIG_HOME/git/ignore has a lower priority.
If *.orig is sitting on the fence, I'd leave it to the users. ]

A long standing issue in the upstream kernel packaging is that the
linux-headers package is not cross-compiled.
For example, you can cross-build Debian packages for arm64 by running
the following command:
$ make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- bindeb-pkg
However, the generated linux-headers-*_arm64.deb is useless because the
host programs in it were built for your build machine architecture
(likely x86), not arm64.
The Debian kernel maintains its own Makefiles to cross-compile host
tools without relying on Kbuild. [1]
Instead of adding such full custom Makefiles, this commit adds a small
piece of code to cross-compile host programs located under the scripts/
directory.
A straightforward solution is to pass HOSTCC=${CROSS_COMPILE}gcc, but it
would also cross-compile scripts/basic/fixdep, which needs to be native
to process the if_changed_dep macro. (This approach may work under some
circumstances; you can execute foreign architecture programs with the
help of binfmt_misc because Debian systems enable CONFIG_BINFMT_MISC,
but it would require installing QEMU and libc for that architecture.)
A trick is to use the external module build (KBUILD_EXTMOD=), which
does not rebuild scripts/basic/fixdep. ${CC} needs to be able to link
userspace programs (CONFIG_CC_CAN_LINK=y).
There are known limitations:
- GCC plugins
It would possible to rebuild GCC plugins for the target architecture
by passing HOSTCXX=${CROSS_COMPILE}g++ with necessary packages
installed, but gcc on the installed system emits
"cc1: error: incompatible gcc/plugin versions".
- objtool and resolve_btfids
These are built by the tools build system. They are not covered by
the current solution. The resulting linux-headers package is broken
if CONFIG_OBJTOOL or CONFIG_DEBUG_INFO_BTF is enabled.
I only tested this with Debian, but it should work for other package
systems as well.

PARF hardware block which is a wrapper on top of DWC PCIe controller
mirrors the DBI and ATU register space. It uses PARF_SLV_ADDR_SPACE_SIZE
register to get the size of the memory block to be mirrored and uses
PARF_DBI_BASE_ADDR, PARF_ATU_BASE_ADDR registers to determine the base
address of DBI and ATU space inside the memory block that is being
mirrored.
When a memory region which is located above the SLV_ADDR_SPACE_SIZE
boundary is used for BAR region then there could be an overlap of DBI and
ATU address space that is getting mirrored and the BAR region. This
results in DBI and ATU address space contents getting updated when a PCIe
function driver tries updating the BAR/MMIO memory region. Reference
memory map of the PCIe memory region with DBI and ATU address space
overlapping BAR region is as below.

Currently memory region beyond the SLV_ADDR_SPACE_SIZE boundary is not
used for BAR region which is why the above mentioned issue is not
encountered. This issue is discovered as part of internal testing when we
tried moving the BAR region beyond the SLV_ADDR_SPACE_SIZE boundary. Hence
we are trying to fix this.
As PARF hardware block mirrors DBI and ATU register space after every
PARF_SLV_ADDR_SPACE_SIZE (default 0x1000000) boundary multiple, program
maximum possible size to this register by writing 0x80000000 to it(it
considers only powers of 2 as values) to avoid mirroring DBI and ATU to
BAR/MMIO region. Write the physical base address of DBI and ATU register
blocks to PARF_DBI_BASE_ADDR (default 0x0) and PARF_ATU_BASE_ADDR (default
0x1000) respectively to make sure DBI and ATU blocks are at expected
memory locations.
The register offsets PARF_DBI_BASE_ADDR_V2, PARF_SLV_ADDR_SPACE_SIZE_V2
and PARF_ATU_BASE_ADDR are applicable for platforms that use Qcom IP
rev 1.9.0, 2.7.0 and 2.9.0. PARF_DBI_BASE_ADDR_V2 and
PARF_SLV_ADDR_SPACE_SIZE_V2 are applicable for Qcom IP rev 2.3.3.
PARF_DBI_BASE_ADDR and PARF_SLV_ADDR_SPACE_SIZE are applicable for Qcom
IP rev 1.0.0, 2.3.2 and 2.4.0. Update init()/post_init() functions of the
respective Qcom IP versions to program applicable PARF_DBI_BASE_ADDR,
PARF_SLV_ADDR_SPACE_SIZE and PARF_ATU_BASE_ADDR register offsets. Update
the SLV_ADDR_SPACE_SZ macro to 0x80000000 to set highest bit in
PARF_SLV_ADDR_SPACE_SIZE register.
Cache DBI and iATU physical addresses in 'struct dw_pcie' so that
pcie_qcom.c driver can program these addresses in the PARF_DBI_BASE_ADDR
and PARF_ATU_BASE_ADDR registers.

Historically, Qcom PCIe RC controllers lacked standard hotplug support. So
when an endpoint is attached to the SoC, users have to rescan the bus
manually to enumerate the device. But this can be avoided by using the Link
up event exposed by the Qcom specific 'global_irq' interrupt.
Qcom PCIe RC controllers are capable of generating the 'global' SPI
interrupt to the host CPUs. The device driver can use this interrupt to
identify events such as PCIe link specific events, safety events etc...
One such event is the PCIe Link up event generated when an endpoint is
detected on the bus and the Link is 'up'. This event can be used to
enumerate the PCIe endpoint devices without user intervention.
So add support for capturing the PCIe Link up event using the 'global'
interrupt in the driver. Once the Link up event is received, the bus
underneath the host bridge is scanned to enumerate PCIe endpoint devices.
All of the Qcom SoCs have only one Root Port per controller instance. So
only a single 'Link up' event is generated for the PCIe controller.

Currently, the IRQ device name for both of these IRQs doesn't have Qcom

1. Pollutes the global IRQ namespace since 'global' is a common name.
2. When more than one EP controller instance is present in the SoC, naming
conflict will occur.
Hence, add 'qcom_pcie_ep_' prefix and PCIe domain number suffix to the IRQ
names to uniquely identify the IRQs and also to fix the above mentioned

Right now, PCI endpoint subsystem doesn't assign PCI domain number for the
PCI endpoint controllers. But this domain number could be useful to the EPC
drivers to uniquely identify each controller based on the hardware instance
when there are multiple ones present in an SoC (even multiple RC/EP).
So let's make use of the existing pci_bus_find_domain_nr() API to allocate
domain numbers based on either devicetree (linux,pci-domain) property or
dynamic domain number allocation scheme.
It should be noted that the domain number allocated by this API will be
based on both RC and EP controllers in a SoC. If the 'linux,pci-domain' DT
property is present, then the domain number represents the actual hardware
instance of the PCI endpoint controller. If not, then the domain number
will be allocated based on the PCI EP/RC controller probe order.
If the architecture doesn't support CONFIG_PCI_DOMAINS_GENERIC (rare), then
currently a warning is thrown to indicate that the architecture specific
implementation is needed.

The different revisions of the Zinitix BTXXX touchscreens place
the icon status register (to read out touchkey status) in
different places. Use the chip revision bits to discern
between the different versions at runtime.
This makes touchkeys work on the BT404 on the Samsung Codina
GT-I8160 mobile phone.

The chip hardware revision, firmware version and regdata
revision is needed to discern because for example touchkeys
are handled by different registers on different versions of
the chip. Example output from BT404:
Zinitix-TS 3-0020: chip revision 4040 firmware version 0088
regdata version 0004

The merge of imx-spdif driver into fsl-asoc-card brought
new DT properties that can be used with the "fsl,imx-audio-spdif"
compatible:
* The "spdif-controller" property from imx-spdif is named "audio-cpu"
in fsl-asoc-card.
* fsl-asoc-card uses codecs explicitly declared in DT
with "audio-codec".
With an S/PDIF, codec drivers spdif_transmitter and
spdif_receiver should be used.
Driver imx-spdif used instead the dummy codec and a pair of
boolean properties, "spdif-in" and "spdif-out".
While backward compatibility is kept to support properties
"spdif-controller", "spdif-in" and "spdif-out", using new properties has
several benefits:
* "audio-cpu" and "audio-codec" are more generic names reflecting
that the fsl-asoc-card driver supports multiple hardware.
They are properties already used by devices using the
fsl-asoc-card driver.
They are also similar to properties of simple-card: "cpu" and "codec".
* "spdif-in" and "spdif-out" imply the use of the dummy codec in the
driver. However, there are already two codec drivers for the S/PDIF,
spdif_transmitter and spdif_receiver.
It is better to declare S/PDIF Tx and Rx devices in a DT, and then
reference them with "audio-codec" than using the dummy codec.
For those reasons, this commit updates in-tree DTs to use the new
properties:
* Rename "spdif-controller" property to "audio-cpu".
* Declare S/PDIF transmitter and/or receiver devices, and use them with
the "audio-codec" property instead of "spdif-out" and/or "spdif-in".
These modifications were tested only on an imx8mn-evk board.
Note that out-of-tree and old DTs are still supported.

We had a report of data corruption on nixos when building installer
images.
https://github.com/NixOS/nixpkgs/pull/321055#issuecomment-2184131334
It seems that writes are being dropped, but only when issued by QEMU,
and possibly only in snapshot mode. It's undetermined if it's write
calls are being dropped or dirty folios.
Further testing, via minimizing the original patch to just the change
that skips the inode lock on non appends/truncates, reveals that it
really is just not taking the inode lock that causes the corruption: it
has nothing to do with the other logic changes for preserving write
atomicity in corner cases.
It's also kernel config dependent: it doesn't reproduce with the minimal
kernel config that ktest uses, but it does reproduce with nixos's distro
config. Bisection the kernel config initially pointer the finger at page
migration or compaction, but it appears that was erroneous; we haven't
yet determined what kernel config option actually triggers it.
Sadly it appears this will have to be reverted since we're getting too
close to release and my plate is full, but we'd _really_ like to fully
debug it.
My suspicion is that this patch is exposing a preexisting bug - the
inode lock actually covers very little in IO paths, and we have a
different lock (the pagecache add lock) that guards against races with
truncate here.

There is a fairly large number of bug fixes for Qualcomm platforms,

The Qualcomm driver changes address a few build-time issues as well
as runtime problems in the tzmem and scm firmware, the USB Type-C
driver, and the cmd-db and pmic_glink soc drivers.
The NXP i.MX usually gets a bunch of devicetree fixes that is proportional
to the number of supported machines. This includes both warning fixes
and correctness for the 64-bit i.MX9, i.MX8 and layerscape platforms,
as well as a single fix for a 32-bit i.MX6 based board.
The other changes are the usual minor changes, including an update to the
MAINTAINERS file, an omap3 dts file and a SoC driver for mpfs (risc-v).

====================
Unmask upper DSCP bits - part 2
tl;dr - This patchset continues to unmask the upper DSCP bits in the
IPv4 flow key in preparation for allowing IPv4 FIB rules to match on
DSCP. No functional changes are expected. Part 1 was merged in commit
("Merge branch 'unmask-upper-dscp-bits-part-1'").
The TOS field in the IPv4 flow key ('flowi4_tos') is used during FIB
lookup to match against the TOS selector in FIB rules and routes.
It is currently impossible for user space to configure FIB rules that
match on the DSCP value as the upper DSCP bits are either masked in the
various call sites that initialize the IPv4 flow key or along the path
to the FIB core.
In preparation for adding a DSCP selector to IPv4 and IPv6 FIB rules, we
need to make sure the entire DSCP value is present in the IPv4 flow key.
This patchset continues to unmask the upper DSCP bits, but this time in
the output route path.
Patches #1-#3 unmask the upper DSCP bits in the various places that
invoke the core output route lookup functions directly.
Patches #4-#6 do the same in three helpers that are widely used in the
output path to initialize the TOS field in the IPv4 flow key.
The rest of the patches continue to unmask these bits in call sites that
invoke the following wrappers around the core lookup functions:
Patch #7 - __ip_route_output_key()
Patches #8-#12 - ip_route_output_flow()
The next patchset will handle the callers of ip_route_output_ports() and
ip_route_output_key().
No functional changes are expected as commit 1fa3314c14 ("ipv4:
Centralize TOS matching") moved the masking of the upper DSCP bits to
the core where 'flowi4_tos' is matched against the TOS selector.
Changes since v1 [1]:
* Remove IPTOS_RT_MASK in patch #7 instead of in patch #6
