x86/its: Enable Indirect Target Selection mitigation
Indirect Target Selection (ITS) is a bug in some pre-ADL Intel CPUs with eIBRS. It affects prediction of indirect branch and RETs in the lower half of cacheline. Due to ITS such branches may get wrongly predicted to a target of (direct or indirect) branch that is located in the upper half of the cacheline. Scope of impact =============== Guest/host isolation -------------------- When eIBRS is used for guest/host isolation, the indirect branches in the VMM may still be predicted with targets corresponding to branches in the guest. Intra-mode ---------- cBPF or other native gadgets can be used for intra-mode training and disclosure using ITS. User/kernel isolation --------------------- When eIBRS is enabled user/kernel isolation is not impacted. Indirect Branch Prediction Barrier (IBPB) ----------------------------------------- After an IBPB, indirect branches may be predicted with targets corresponding to direct branches which were executed prior to IBPB. This is mitigated by a microcode update. Add cmdline parameter indirect_target_selection=off|on|force to control the mitigation to relocate the affected branches to an ITS-safe thunk i.e. located in the upper half of cacheline. Also add the sysfs reporting. When retpoline mitigation is deployed, ITS safe-thunks are not needed, because retpoline sequence is already ITS-safe. Similarly, when call depth tracking (CDT) mitigation is deployed (retbleed=stuff), ITS safe return thunk is not used, as CDT prevents RSB-underflow. To not overcomplicate things, ITS mitigation is not supported with spectre-v2 lfence;jmp mitigation. Moreover, it is less practical to deploy lfence;jmp mitigation on ITS affected parts anyways.

drm/xe/hwmon: Fix kernel version documentation for temperature
The version in the sysfs attribute should correspond to the version in which this is enabled and visible for end users. It usually doesn't correspond to the version in which the patch was developed, but rather a release that will contain it. Update them to 6.15. Fixes: |

HID: hid-appletb-kbd: Fix wrong date and kernel version in sysfs interface docs
The driver hid-appletb-kbd was upstreamed in kernel 6.15. But, due to an oversight on my part, I didn't change the kernel version and expected date while upstreaming the driver, thus it remained as 6.5, the original kernel version when the driver was developed for downstream. This commit should fix this. Signed-off-by: Aditya Garg <gargaditya08@live.com> Signed-off-by: Jiri Kosina <jkosina@suse.com> |

scsi: ufs: core: Add device level exception support
The ufs device JEDEC specification version 4.1 adds support for the device level exception events. To support this new device level exception feature, expose two new sysfs nodes below to provide the user space access to the device level exception information. /sys/bus/platform/drivers/ufshcd/*/device_lvl_exception_count /sys/bus/platform/drivers/ufshcd/*/device_lvl_exception_id The device_lvl_exception_count sysfs node reports the number of device level exceptions that have occurred since the last time this variable is reset. Writing a value of 0 will reset it. The device_lvl_exception_id reports the exception ID which is the qDeviceLevelExceptionID attribute of the device JEDEC specifications version 4.1 and later. The user space application can query these sysfs nodes to get more information about the device level exception. Signed-off-by: Bao D.

- The 6 patch series "Enable strict percpu address space checks" from
Uros Bizjak uses x86 named address space qualifiers to provide compile-time checking of percpu area accesses. This has caused a small amount of fallout - two or three issues were reported. In all cases the calling code was founf to be incorrect. - The 4 patch series "Some cleanup for memcg" from Chen Ridong implements some relatively monir cleanups for the memcontrol code. - The 17 patch series "mm: fixes for device-exclusive entries (hmm)" from David Hildenbrand fixes a boatload of issues which David found then using device-exclusive PTE entries when THP is enabled. More work is needed, but this makes thins better - our own HMM selftests now succeed. - The 2 patch series "mm: zswap: remove z3fold and zbud" from Yosry Ahmed remove the z3fold and zbud implementations. They have been deprecated for half a year and nobody has complained. - The 5 patch series "mm: further simplify VMA merge operation" from Lorenzo Stoakes implements numerous simplifications in this area. No runtime effects are anticipated. - The 4 patch series "mm/madvise: remove redundant mmap_lock operations from process_madvise()" from SeongJae Park rationalizes the locking in the madvise() implementation. Performance gains of 20-25% were observed in one MADV_DONTNEED microbenchmark. - The 12 patch series "Tiny cleanup and improvements about SWAP code" from Baoquan He contains a number of touchups to issues which Baoquan noticed when working on the swap code. - The 2 patch series "mm: kmemleak: Usability improvements" from Catalin Marinas implements a couple of improvements to the kmemleak user-visible output. - The 2 patch series "mm/damon/paddr: fix large folios access and schemes handling" from Usama Arif provides a couple of fixes for DAMON's handling of large folios. - The 3 patch series "mm/damon/core: fix wrong and/or useless damos_walk() behaviors" from SeongJae Park fixes a few issues with the accuracy of kdamond's walking of DAMON regions. - The 3 patch series "expose mapping wrprotect, fix fb_defio use" from Lorenzo Stoakes changes the interaction between framebuffer deferred-io and core MM. No functional changes are anticipated - this is preparatory work for the future removal of page structure fields. - The 4 patch series "mm/damon: add support for hugepage_size DAMOS filter" from Usama Arif adds a DAMOS filter which permits the filtering by huge page sizes. - The 4 patch series "mm: permit guard regions for file-backed/shmem mappings" from Lorenzo Stoakes extends the guard region feature from its present "anon mappings only" state.

Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Enable Configuration RRS SV, which makes device readiness visible,

space to assign some BARs (Kai-Heng Feng)
- Relax bridge window tail sizing for optional resources, e.g., IOV
BARs, to avoid failures when removing and re-adding devices (Ilpo
Järvinen)
- Allow drivers to enable devices even if we haven't assigned
optional IOV resources to them (Ilpo Järvinen)
- Rework handling of optional resources (IOV BARs, ROMs) to reduce
failures if we can't allocate them (Ilpo Järvinen)
- Fix a NULL dereference in the SR-IOV VF creation error path (Shay

can still access devices after pci_stop_dev() (Manivannan
Sadhasivam)

- Drop 'shpchp_debug' module parameter in favor of standard dynamic
debugging (Ilpo Järvinen)
- Drop unused cpcihp .get_power(), .set_power() function pointers

to address a deadlock when resuming after a device was removed
during system sleep (Lukas Wunner)

Dave)
DOE:
- Expose supported DOE features via sysfs (Alistair Francis)

Francis)
Endpoint framework:
- Convert PCI device data so pci-epf-test works correctly on
big-endian endpoint systems (Niklas Cassel)
- Add BAR_RESIZABLE type to endpoint framework and add DWC core
support for EPF drivers to set BAR_RESIZABLE type and size (Niklas
Cassel)
- Fix pci-epf-test double free that causes an oops if the host
reboots and PERST# deassertion restarts endpoint BAR allocation
(Christian Bruel)

writable register, not the read-only config register (Jim Quinlan)
- Handle regulator_bulk_get() error to avoid panic when we call
regulator_bulk_free() later (Jim Quinlan)
- Disable regulators only when removing the bus immediately below a
Root Port because we don't support regulators deeper in the
hierarchy (Jim Quinlan)

Merge tag 'drm-next-2025-03-28' of https://gitlab.freedesktop.org/drm/kernel
Pull drm updates from Dave Airlie:
"Outside of drm there are some rust patches from Danilo who maintains
that area in here, and some pieces for drm header check tests.
The major things in here are a new driver supporting the touchbar
displays on M1/M2, the nova-core stub driver which is just the vehicle
for adding rust abstractions and start developing a real driver inside
of.
xe adds support for SVM with a non-driver specific SVM core
abstraction that will hopefully be useful for other drivers, along
with support for shrinking for TTM devices. I'm sure xe and AMD
support new devices, but the pipeline depth on these things is hard to
know what they end up being in the marketplace!

f2fs-for-6.15-rc1
In this round, there are three major updates: 1) folio conversion, 2) refactor for mount API conversion, 3) some performance improvement such as direct IO, checkpoint speed, and IO priority hints. For stability, there are patches which add more sanity checks and fixes some major issues like i_size in atomic write operations and write pointer recovery in zoned devices. Enhancement: - huge folio converion work by Matthew Wilcox - clean up for mount API conversion by Eric Sandeen - improve direct IO speed in the overwrite case - add some sanity check on node consistency - set highest IO priority for checkpoint thread - keep POSIX_FADV_NOREUSE ranges and add sysfs entry to reclaim pages - add ioctl to get IO priority hint - add carve_out sysfs node for fsstat Bug fix: - disable nat_bits during umount to avoid potential nat entry corruption - fix missing i_size update on atomic writes - fix missing discard for active segments - fix running out of free segments - fix out-of-bounds access in f2fs_truncate_inode_blocks() - call f2fs_recover_quota_end() correctly - fix potential deadloop in prepare_compress_overwrite() - fix the missing write pointer correction for zoned device - fix to avoid panic once fallocation fails for pinfile - don't retry IO for corrupted data scenario There are many other clean up patches and minor bug fixes as usual. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE00UqedjCtOrGVvQiQBSofoJIUNIFAmfhjuYACgkQQBSofoJI UNJF+hAAip0Sf6bXwt43KR3lmbXg/YBTtPDACOs375Pn8pfRVsAPIAf5e1AnlBET rA0KpqUrEZHXenQFF9n4LIoHYqfuUw3EMempuvp4qgQcx15Kaajw+EGWVLYstNy2 9dELc9DA55f/i1uvHezGfQFy6hMfXasf+tkaYk0z0ZYDStYboLgkVAY+F869q1Dl D16Y7Lna12h4eCxDdssIPDsLjFH/2LDn7SmhXsnpZxwK0Zx8JSo83WxXHnzXHxz4 vUkukInKgqcBDvf6ufW/YF3/tqSs20XEXNK3cI1vyHx1dwij6Us+G0n0WJHL30QE zsliecR0X28JP1rJ3ldCjr+4Kxm6/u/Uwpinm2Fm1jL67UY4TZcaARBE8k20I6ND j/L1+sXrIdZ1aILM9/bwCjgXiVFdZbvlfGfpTj1duAkQgRd+/s9cjPlo5j5HTad5 XJmzJz6YOaUNarhP/E31Z9SV9M2kEcmoDOTxKBg6ZcMWXZ27B6Z0ag92prd0GWk6 rWDuVj0eP/LDY1QedbHRPbg1D84jVgcnldfPaf9ptln993skJGdgS0dkegTqMR0L H8RgpWOzWZI53gnQdePdej8diHmD8uRTrLf/oABm//GzTHC5BdwVpArOl1DCuLFF YkMtVEicgnWRmL3PgODAdTJXaDi3uGvT116i+lfMlUn9p+t93r0= =E+TE -----END PGP SIGNATURE----- Merge tag 'f2fs-for-6.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs Pull f2fs updates from Jaegeuk Kim: "In this round, there are three major updates: (1) folio conversion, (2) refactoring for mount API conversion, (3) some performance improvement such as direct IO, checkpoint speed, and IO priority hints.

PCI/DOE: Expose DOE features via sysfs
PCIe r6.0 added support for Data Object Exchange (DOE). When DOE is supported, the DOE Discovery Feature must be implemented per PCIe r6.1, sec 6.30.1.1. DOE allows a requester to obtain information about the other DOE features supported by the device. The kernel already queries the DOE features supported and caches the values. Expose the values in sysfs to allow user space to determine which DOE features are supported by the PCIe device. By exposing the information to userspace, tools like lspci can relay the information to users. By listing all of the supported features we can allow userspace to parse the list, which might include vendor specific features as well as yet to be supported features. As the DOE Discovery feature must always be supported we treat it as a special named attribute case. This allows the usual PCI attribute_group handling to correctly create the doe_features directory when registering pci_doe_sysfs_group (otherwise it doesn't and sysfs_add_file_to_group() will seg fault). After this patch is supported you can see something like this when attaching a DOE device: $ ls /sys/devices/pci0000:00/0000:00:02.0//doe* 0001:01 0001:02 doe_discovery Link: https://lore.kernel.org/r/20250306075211.1855177-3-alistair@alistair23.me Signed-off-by: Alistair Francis <alistair@alistair23.me> [bhelgaas: drop pci_doe_sysfs_init() stub return, make DEVICE_ATTR_RO(doe_discovery) static] Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Reviewed-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> |

reboot: add support for configuring emergency hardware protection action
We currently leave the decision of whether to shutdown or reboot to protect hardware in an emergency situation to the individual drivers. This works out in some cases, where the driver detecting the critical failure has inside knowledge: It binds to the system management controller for example or is guided by hardware description that defines what to do. In the general case, however, the driver detecting the issue can't know what the appropriate course of action is and shouldn't be dictating the policy of dealing with it. Therefore, add a global hw_protection toggle that allows the user to specify whether shutdown or reboot should be the default action when the driver doesn't set policy. This introduces no functional change yet as hw_protection_trigger() has no callers, but these will be added in subsequent commits.

mm/cma: export total and free number of pages for CMA areas
Patch series "hugetlb/CMA improvements for large systems", v5. On large systems, we observed some issues with hugetlb and CMA: 1) When specifying a large number of hugetlb boot pages (hugepages= on the commandline), the kernel may run out of memory before it even gets to HVO. For example, if you have a 3072G system, and want to use 3024 1G hugetlb pages for VMs, that should leave you plenty of space for the hypervisor, provided you have the hugetlb vmemmap optimization (HVO) enabled. However, since the vmemmap pages are always allocated first, and then later in boot freed, you will actually run yourself out of memory before you can do HVO. This means not getting all the hugetlb pages you want, and worse, failure to boot if there is an allocation failure in the system from which it can't recover. 2) There is a system setup where you might want to use hugetlb_cma with a large value (say, again, 3024 out of 3072G like above), and then lower that if system usage allows it, to make room for non-hugetlb processes. For this, a variation of the problem above applies: the kernel runs out of unmovable space to allocate from before you finish boot, since your CMA area takes up all the space. 3) CMA wants to use one big contiguous area for allocations. Which fails if you have the aforementioned 3T system with a gap in the middle of physical memory (like the < 40bits BIOS DMA area seen on some AMD systems). You then won't be able to set up a CMA area for one of the NUMA nodes, leading to loss of half of your hugetlb CMA area. 4) Under the scenario mentioned in 2), when trying to grow the number of hugetlb pages after dropping it for a while, new CMA allocations may fail occasionally. This is not unexpected, some transient references on pages may prevent cma_alloc from succeeding under memory pressure. However, the hugetlb code then falls back to a normal contiguous alloc, which may end up succeeding. This is not always desired behavior. If you have a large CMA area, then the kernel has a restricted amount of memory it can do unmovable allocations from (a well known issue). A normal contiguous alloc may eat further in to this space. To resolve these issues, do the following: * Add hooks to the section init code to do custom initialization of memmap pages. Hugetlb bootmem (memblock) allocated pages can then be pre-HVOed. This avoids allocating a large number of vmemmap pages early in boot, only to have them be freed again later, and also avoids running out of memory as described under 1). Using these hooks for hugetlb is optional. It requires moving hugetlb bootmem allocation to an earlier spot by the architecture. This has been enabled on x86. * hugetlb_cma doesn't care about the CMA area it uses being one large contiguous range. Multiple smaller ranges are fine. The only requirements are that the areas should be on one NUMA node, and individual gigantic pages should be allocatable from them. So, implement multi-range support for CMA, avoiding issue 3). * Introduce a hugetlb_cma_only option on the commandline. This only allows allocations from CMA for gigantic pages, if hugetlb_cma= is also specified. * With hugetlb_cma_only active, it also makes sense to be able to pre-allocate gigantic hugetlb pages at boot time from the CMA area(s). Add a rudimentary early CMA allocation interface, that just grabs a piece of memblock-allocated space from the CMA area, which gets marked as allocated in the CMA bitmap when the CMA area is initialized. With this, hugepages= can be supported with hugetlb_cma=, making scenario 2) work. Additionally, fix some minor bugs, with one worth mentioning: since hugetlb gigantic bootmem pages are allocated by memblock, they may span multiple zones, as memblock doesn't (and mostly can't) know about zones. This can cause problems. A hugetlb page spanning multiple zones is bad, and it's worse with HVO, when the de-HVO step effectively sneakily re-assigns pages to a different zone than originally configured, since the tail pages all inherit the zone from the first 60 tail pages. This condition is not common, but can be easily reproduced using ZONE_MOVABLE. To fix this, add checks to see if gigantic bootmem pages intersect with multiple zones, and do not use them if they do, giving them back to the page allocator instead. The first patch is kind of along for the ride, except that maintaining an available_count for a CMA area is convenient for the multiple range support. This patch (of 27): In addition to the number of allocations and releases, system management software may like to be aware of the size of CMA areas, and how many pages are available in it. This information is currently not available, so export it in total_page and available_pages, respectively. The name 'available_pages' was picked over 'free_pages' because 'free' implies that the pages are unused. But they might not be, they just haven't been used by cma_alloc The number of available pages is tracked regardless of CONFIG_CMA_SYSFS, allowing for a few minor shortcuts in the code, avoiding bitmap operations.

IIO: New device support, features and cleanup for the 6.15 cycle.

f2fs: add carve_out sysfs node
For several zoned storage devices, vendors will provide extra space which was used for device level GC than specs and F2FS can use this space for filesystem level GC. To do that, we can reserve the space using reserved_blocks. However, it is not enough, since this extra space should not be shown to users. So, with this new sysfs node, we can hide the space by substracting reserved_blocks from total bytes.
