2025-01-10dt-bindings: display: Correct indentation and style in DTS exampleKrzysztof Kozlowski
DTS example in the bindings should be indented with 2- or 4-spaces and aligned with opening '- |', so correct any differences like 3-spaces or mixtures 2- and 4-spaces in one binding. No functional changes here, but saves some comments during reviews of new patches built on existing code.

2025-01-10pps: adjust references to actual name of uapi header fileLukas Bulwahn
Commit 86b525bed275 ("drivers pps: add PPS generators support") adds a file entry in MAINTAINERS and a reference in the ioctl-number documentation referring to the file pps-gen.h, whereas the file added in this commit is named pps_gen.h. Adjust the two references to the actual name of the uapi header file. While at it, put the entry in MAINTAINERS at the right place for alphabetical ordering.

2025-01-10kheaders: use 'tar' instead of 'cpio' for copying filesMasahiro Yamada
The 'cpio' command is used solely for copying header files to the temporary directory. However, there is no strong reason to use 'cpio' for this purpose. For example, scripts/package/install-extmod-build uses the 'tar' command to copy files. This commit replaces the use of 'cpio' with 'tar' because 'tar' is already used in this script to generate kheaders_data.tar.xz anyway. Performance-wide, there is no significant difference between 'cpio' and 'tar'. [Before] $ rm -fr kheaders; mkdir kheaders $ time sh -c ' for f in include arch/x86/include do find "$f" -name "*.h" done | cpio --quiet -pd kheaders ' real 0m0.148s user 0m0.021s sys 0m0.140s [After] $ rm -fr kheaders; mkdir kheaders $ time sh -c ' for f in include arch/x86/include do find "$f" -name "*.h" done | tar -c -f - -T - | tar -xf - -C kheaders ' real 0m0.098s user 0m0.024s sys 0m0.131s Revert commit 69ef0920bdd3 ("Docs: Add cpio requirement to changes.rst") because 'cpio' is not used anywhere else during the kernel build. Please note that the built-in initramfs is created by the in-tree tool, usr/gen_init_cpio, so it does not rely on the external 'cpio' command at all. Remove 'cpio' from the package build dependencies as well. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2025-01-10perf tools: Remove dependency on libauditCharlie Jenkins
All architectures now support HAVE_SYSCALL_TABLE_SUPPORT, so the flag is no longer needed.

2025-01-09netdev: define NETDEV_INTERNALJakub Kicinski
Linus suggested during one of past maintainer summits (in context of a DMA_BUF discussion) that symbol namespaces can be used to prevent unwelcome but in-tree code from using all exported functions. Create a namespace for netdev. Export netdev_rx_queue_restart(), drivers may want to use it since it gives them a simple and safe way to restart a queue to apply config changes.

2025-01-08arm64: Filter out SVE hwcaps when FEAT_SVE isn't implementedMarc Zyngier
The hwcaps code that exposes SVE features to userspace only considers ID_AA64ZFR0_EL1, while this is only valid when ID_AA64PFR0_EL1.SVE advertises that SVE is actually supported. The expectations are that when ID_AA64PFR0_EL1.SVE is 0, the ID_AA64ZFR0_EL1 register is also 0. So far, so good. Things become a bit more interesting if the HW implements SME. In this case, a few ID_AA64ZFR0_EL1 fields indicate *SME* features. And these fields overlap with their SVE interpretations. But the architecture says that the SME and SVE feature sets must match, so we're still hunky-dory. This goes wrong if the HW implements SME, but not SVE. In this case, we end-up advertising some SVE features to userspace, even if the HW has none. That's because we never consider whether SVE is actually implemented. Oh well. Fix it by restricting all SVE capabilities to ID_AA64PFR0_EL1.SVE being non-zero. The HWCAPS documentation is amended to reflect the actually checks performed by the kernel.
