Reorganize the Curve25519 library code:
- Build a single libcurve25519 module, instead of up to three modules:
libcurve25519, libcurve25519-generic, and an arch-specific module.
- Move the arch-specific Curve25519 code from arch/$(SRCARCH)/crypto/ to
lib/crypto/$(SRCARCH)/. Centralize the build rules into
lib/crypto/Makefile and lib/crypto/Kconfig.
- Include the arch-specific code directly in lib/crypto/curve25519.c via
a header, rather than using a separate .c file.
- Eliminate the entanglement with CRYPTO. CRYPTO_LIB_CURVE25519 no
longer selects CRYPTO, and the arch-specific Curve25519 code no longer
depends on CRYPTO.
This brings Curve25519 in line with the latest conventions for
lib/crypto/, used by other algorithms. The exception is that I kept the
generic code in separate translation units for now. (Some of the
function names collide between the x86 and generic Curve25519 code. And
the Curve25519 functions are very long anyway, so inlining doesn't
matter as much for Curve25519 as it does for some other algorithms.)

Move the Curve25519 test from an ad-hoc self-test to a KUnit test.
Generally keep the same test logic for now, just translated to KUnit.
There's one exception, which is that I dropped the incomplete test of
curve25519_generic(). The approach I'm taking to cover the different
implementations with the KUnit tests is to just rely on booting kernels
in QEMU with different '-cpu' options, rather than try to make the tests
(incompletely) test multiple implementations on one CPU. This way, both
the test and the library API are simpler.
This commit makes the file lib/crypto/curve25519.c no longer needed, as
its only purpose was to call the self-test. However, keep it for now,
since a later commit will add code to it again.
Temporarily omit the default value of CRYPTO_SELFTESTS that the other
lib/crypto/ KUnit tests have. It would cause a recursive kconfig
dependency, since the Curve25519 code is still entangled with CRYPTO. A
later commit will fix that.

Support "\e[?1049h" and "\e[?1049l" escape codes.
This patch allows programs to enter and leave alternate screens.
This feature is widely available in graphical terminal emulators and mostly
used by fullscreen terminal-based user interfaces such as text editors.
Most editors such as vim and nano assume this escape code in not supported
and will not try to print the escape sequence if TERM=linux.
To try out this patch, run `TERM=xterm-256color vim` inside a VT.

Sakari Ailus <sakari.ailus@linux.intel.com> says:
This series enables support for eUSB2 Double Isochronous IN Bandwidth UVC
devices specified in 'USB 2.0 Double Isochronous IN Bandwidth' ECN. In
short, it adds support for new integrated USB2 webcams that can send twice
the data compared to conventional USB2 webcams.
These devices are identified by the device descriptor bcdUSB 0x0220 value.
They have an additional eUSB2 Isochronous Endpoint Companion Descriptor,
and a zero max packet size in regular isoc endpoint descriptor. Support
for parsing that new descriptor was added in commit
c749f058b437 ("USB: core: Add eUSB2 descriptor and parsing in USB core")
This series adds support to UVC, USB core, and xHCI to identify eUSB2
double isoc devices, and allow and set proper max packet, iso frame desc
sizes, bytes per interval, and other values in URBs and xHCI endpoint
contexts needed to support the double data rates for eUSB2 double isoc
devices.
since v4:
https://lore.kernel.org/linux-usb/20250812132445.3185026-1-sakari.ailus@linux.intel.com
- New patch: use le16_to_cpu() to access endpoint descriptor's
wMaxPacketSize field, which is an __le16. This isn't a bugfix as the
value was compared to 0.
- New patch: add USB device speed check for eUSB2 isochronous endpoint
companion parsing. The check is then removed from sites checking the
existence of the companion (through companion's bDescriptorType field,
which is non-zero for valid descriptors).
- New patch: do not parse eUSB2 isoc double BW companion descriptor on
interrupt or OUT endpoints. It is not supposed to be found there,
according to the ECN.
- Rename usb_endpoint_max_isoc_bpi() as
usb_endpoint_max_periodic_payload() and move it right after
usb_maxpacket().
- Fixed @ep reference in kernel-doc documentation for
usb_endpoint_max_periodic_payload().
- In usb_endpoint_max_periodic_payload(), call struct usb_device pointer
argument "udev" instead of "dev", to align with naming elsewhere.
- Add support for interrupt endpoints in
usb_endpoint_max_periodic_payload(); eUSB2 double isoc BW is still
limited to isochronous endpoints though.
- In usb_endpoint_max_periodic_payload(), remove the separate case for
USB_SPEED_HIGH as the check is already done in parsing the eUSB isoc
double BW companion, which is checked for.
- New patch: use usb_endpoint_max_periodic_payload() in xHCI driver,
replacing xhci_get_max_esit_payload().
- Check non-zero bDescriptorType field of ep->eusb2_isoc_ep_comp instead
of dwBytesPerInterval value exceeding 3072, where
xhci_eusb2_is_isoc_bw_double() was used. This aligns the checks of eUSB2
isochronous double bandwidth support for an endpoint.
- New patch: introduce usb_endpoint_is_hs_isoc_double() to figure out
whether an endpoint uses isochronous double bandwidth and use the
function in the xHCI driver and the usb core.
xhci_eusb2_is_isoc_bw_double() is dropped, as well as the
MAX_ISOC_XFER_SIZE_HS macro. usb_endpoint_is_hs_isoc_double() also
includes check for bcdUSB == 0x220, to anticipate adding support for
eUSB2V2.
- Merge condition for checking eUSB2 isoc double bw support for
xHCI/endpoint in xhci_get_endpoint_mult().
- Improve comment regarding maximum packet size bits 12:11 in
xhci_get_endpoint_max_burst().
- Aligned subject prefixes with the recent patches to the same files.
since v3:
https://lore.kernel.org/linux-usb/20250807055355.1257029-1-sakari.ailus@linux.intel.com/
- Use spaces in aligning macro body for HCC2_EUSB2_DIC() (1st patch).
- Move usb_endpoint_max_isoc_bpi() to drivers/usb/core/usb.c (3rd patch).
since v2:
https://lore.kernel.org/linux-usb/20250711083413.1552423-1-sakari.ailus@linux.intel.com
- Use ep->eusb2_isoc_ep_comp.bDescriptorType to determined whether the
eUSB2 isochronous endpoint companion descriptor exists.
- Clean up eUSB2 double isoc bw maxp calculation.
- Drop le16_to_cpu(udev->descriptor.bcdUSB) == 0x220 check from
xhci_eusb2_is_isoc_bw_double() -- it's redundant as
ep->eusb2_isoc_ep_comp.dwBytesPerInterval will be zero otherwise.
- Add kernel-doc documentation for usb_endpoint_max_isoc_bpi().
- Check the endpoint has IN direction in usb_endpoint_max_isoc_bpi() and
usb_submit_urb() as a condition for eUSB2 isoc double bw.
since v1:
https://lore.kernel.org/linux-usb/20250616093730.2569328-2-mathias.nyman@linux.intel.com
- Introduce uvc_endpoint_max_isoc_bpi() to obtain maximum bytes per
interval value for an endpoint, in a new patch (3rd). This code has been
slightly reworked from the instance in the UVC driver, including support
for SuperSpeedPlus Isochronous Endpoint Companion.
- Use usb_endpoint_max_isoc_bpi() in the UVC driver instead of open-coding
eUSB2 support there, also drop now-redundant uvc_endpoint_max_bpi().
- Use u32 for maximum bpi and related information in the UVC driver -- the
value could be larger than a 16-bit type can hold.
- Assume max in usb_submit_urb() is a natural number as
usb_endpoint_maxp() returns only natural numbers (2nd patch).

Devices with power.no_pm set are not expected to need any power
management at all, so modify device_set_pm_not_required() to set
power.no_callbacks for them too in case runtime PM will be enabled
for any of them (which in principle may be done for convenience if
such a device participates in a dependency chain).
Since device_set_pm_not_required() must be called before device_add()
or it would not have any effect, it can update power.no_callbacks
without locking, unlike pm_runtime_no_callbacks() that can be called
after registering the target device.

Since commit e0b3165ba521 ("cpufreq: add 'freq_table' in struct
cpufreq_policy"), freq_table has been stored in struct cpufreq_policy
instead of being maintained separately.
However, several helpers in freq_table.c still take both policy and
freq_table as parameters, even though policy->freq_table can always be
used. This leads to redundant function arguments and increases the
chance of inconsistencies.
This patch removes the unnecessary freq_table argument from these
functions and updates their callers to only pass policy. This makes
the code simpler, more consistent, and avoids duplication.

Currently if a user enqueue a work item using schedule_delayed_work() the
used wq is "system_wq" (per-cpu wq) while queue_delayed_work() use
WORK_CPU_UNBOUND (used when a cpu is not specified). The same applies to
schedule_work() that is using system_wq and queue_work(), that makes use
again of WORK_CPU_UNBOUND.
This lack of consistentcy cannot be addressed without refactoring the API.
system_wq is a per-CPU worqueue, yet nothing in its name tells about that
CPU affinity constraint, which is very often not required by users. Make
it clear by adding a system_percpu_wq.
queue_work() / queue_delayed_work() mod_delayed_work() will now use the
new per-cpu wq: whether the user still stick on the old name a warn will
be printed along a wq redirect to the new one.
This patch add the new system_percpu_wq except for mm, fs and net
subsystem, whom are handled in separated patches.
The old wq will be kept for a few release cylces.

system_unbound_wq should be the default workqueue so as not to enforce

Adding system_dfl_wq to encourage its use when unbound work should be used.

RISC-V IO Mapping Table (RIMT) is a static ACPI table to communicate
IOMMU information to the OS. The spec is available at [1].
The changes at high level are,
a) Initialize data structures required for IOMMU/device
configuration using the data from RIMT. Provide APIs required
for device configuration.
b) Provide an API for IOMMU drivers to register the
fwnode with RIMT data structures. This API will create a
fwnode for PCIe IOMMU.

Some fuse servers need to prune their caches, which can only be done if the
kernel's own dentry/inode caches are pruned first to avoid dangling
references.
Add FUSE_NOTIFY_PRUNE, which takes an array of node ID's to try and get rid
of. Inodes with active references are skipped.
A similar functionality is already provided by FUSE_NOTIFY_INVAL_ENTRY with
the FUSE_EXPIRE_ONLY flag. Differences in the interface are
FUSE_NOTIFY_INVAL_ENTRY:
- can only prune one dentry
- dentry is determined by parent ID and name
- if inode has multiple aliases (cached hard links), then they would have
to be invalidated individually to be able to get rid of the inode
FUSE_NOTIFY_PRUNE:
- can prune multiple inodes
- inodes determined by their node ID
- aliases are taken care of automatically

Kernel Test Robot reported a compiler warning - a null pointer may be
passed to memmove in __bpf_dynptr_{read,write} when building without

The warning is correct from a static analysis standpoint, but not actually
reachable. Without CONFIG_NET, creating dynptrs to skb metadata is
impossible since the constructor kfunc is missing.
Silence the false-postive diagnostic message by returning an error pointer

Commit 66f793099a63 ("x86/retpoline: Avoid retpolines for built-in __init
functions") disabled retpolines in __init sections (__noinitretpoline)
as a precaution against potential issues with retpolines in early boot,
but it has not been a problem in practice (i.e. see Clang below).
Commit 87358710c1fb ("x86/retpoline: Support retpoline builds with Clang")
narrowed this to only GCC, as Clang doesn't have per-function control
over retpoline emission. As such, Clang has been booting with retpolines
in __init since retpoline support was introduced.
Clang KCFI has been instrumenting __init since CFI was introduced.
With the introduction of KCFI for GCC, KCFI instrumentation with
retpolines disabled means that objtool does not construct .retpoline_sites
section entries for the non-retpoline KCFI calls. At boot, the KCFI
rehashing code, via __apply_fineibt(), misses all __init KCFI calls
(since they are not retpolines), resulting in immediate hash mismatches:
all preambles are rehashed (via .cfi_sites) and none of the __init call
sites are rehashed.
Remove __noinitretpoline since it provides no meaningful utility and
creates problems with CFI. Additionally remove __noretpoline since it
is now unused.
Alternatively, cfi_rand_callers() could walk the .kcfi_traps section which
is exactly the list of KCFI instrumentation sites. But it seems better to
have as few differences in common instruction sequences between compilers
as possible, so better to remove the special handling of retpolines in
__init for GCC.

Prepare for GCC KCFI support and move the __nocfi attribute from
compiler-clang.h to compiler_types.h. This was already gated by
CONFIG_CFI_CLANG, so this remains safe for non-KCFI GCC builds.

cgroup_subsys::post_attach callback was introduced in commit 5cf1cacb49ae
("cgroup, cpuset: replace cpuset_post_attach_flush() with
cgroup_subsys->post_attach callback") and only cpuset would use this
callback to wait for the mm migration to complete at the end of
__cgroup_procs_write(). Since the previous patch defer the flush operation
until returning to userspace, no one use this callback now. Remove this
callback from cgroup_subsys.

Add interface for applications to get information array. The application
provides a buffer pointer along with information type, maximum number of
entries and maximum size of each entry. The buffer may also contain match
conditions based on the information type. After the ioctl completes, the
actual number of entries and entry size are returned. (see [1], used by
driver runtime library)

When reporting an error, the AER driver prints the TLP Header / Prefix Log
only for errors enumerated in the AER_LOG_TLP_MASKS macro.
The macro was never amended since its introduction in 2006 with commit
6c2b374d7485 ("PCI-Express AER implemetation: AER core and aerdriver").
At the time, PCIe r1.1 was the latest spec revision.
Amend the macro with errors defined since then to avoid omitting the TLP
Header / Prefix Log for newer errors.
The order of the errors in AER_LOG_TLP_MASKS follows PCIe r1.1 sec 6.2.7
rather than 7.10.2, because only the former documents for which errors a
TLP Header / Prefix is logged. Retain this order. The section number is
still 6.2.7 in today's PCIe r7.0.
For Completion Timeouts, the TLP Header / Prefix is only logged if the
Completion Timeout Prefix / Header Log Capable bit is set in the AER
Capabilities and Control register. Introduce a tlp_header_logged() helper
to check whether the TLP Header / Prefix Log is populated and use it in
the two places which currently match against AER_LOG_TLP_MASKS directly.
For Uncorrectable Internal Errors, logging of the TLP Header / Prefix is
optional per PCIe r7.0 sec 6.2.7. If needed, drivers could indicate
through a flag whether devices are capable and tlp_header_logged() could
then check that flag.
pcitools introduced macros for newer errors with commit 144b0911cc0b
("ls-ecaps: extend decode support for more fields for AER CE and UE
status"):
https://git.kernel.org/pub/scm/utils/pciutils/pciutils.git/commit/?id=144b0911cc0b
Unfortunately some of those macros are overly long:
PCI_ERR_UNC_POISONED_TLP_EGRESS
PCI_ERR_UNC_DMWR_REQ_EGRESS_BLOCKED
PCI_ERR_UNC_IDE_CHECK
PCI_ERR_UNC_MISR_IDE_TLP
PCI_ERR_UNC_PCRC_CHECK
PCI_ERR_UNC_TLP_XLAT_EGRESS_BLOCKED
This seems unsuitable for <linux/pci_regs.h>, so shorten to:
PCI_ERR_UNC_POISON_BLK
PCI_ERR_UNC_DMWR_BLK
PCI_ERR_UNC_IDE_CHECK
PCI_ERR_UNC_MISR_IDE
PCI_ERR_UNC_PCRC_CHECK
PCI_ERR_UNC_XLAT_BLK
Note that some of the existing macros in <linux/pci_regs.h> do not match
exactly with pcitools (e.g. PCI_ERR_UNC_SDES versus PCI_ERR_UNC_SURPDN),
so it does not seem mandatory for them to be identical.

The so-called fullmac devices rely on firmware functionality and/or API to
change BSS parameters. Today there are limited drivers supporting the
nl80211 primitive, but they only handle a subset of the bss parameters
passed if any. The mac80211 driver does handle all parameters and stores
their configured values. Some of the BSS parameters were already conditional
by wiphy->features. For these the wiphy->bss_param_support and wiphy->features
fields are silently aligned in wiphy_register(). Maybe better to issue a warning
instead when they are misaligned.

MCS mask is constructed by new function, eht_build_mcs_mask(). Max NSS
