- Add check whether the required facilities are installed before using the s390-specific ChaCha20 implementation. - Key blobs for s390 protected key interface IOCTLs commands PKEY_VERIFYKEY2 and PKEY_VERIFYKEY3 may contain clear key material. Zeroize copies of these keys in kernel memory after creating protected keys. - Set CONFIG_INIT_STACK_NONE=y in defconfigs to avoid extra overhead of initializing all stack variables by default. - Make sure that when a new channel-path is enabled all subchannels are evaluated: with and without any devices connected on it. - When SMT thread CPUs are added to CPU topology masks the nr_cpu_ids limit is not checked and could be exceeded. Respect the nr_cpu_ids limit and avoid a warning when CONFIG_DEBUG_PER_CPU_MAPS is set. - The pointer to IPL Parameter Information Block is stored in the absolute lowcore as a virtual address. Save it as the physical address for later use by dump tools. - Fix a Queued Direct I/O (QDIO) problem on z/VM guests using QIOASSIST with dedicated (pass through) QDIO-based devices such as FCP, real OSA or HiperSockets. - s390's struct statfs and struct statfs64 contain padding, which field-by-field copying does not set. Initialize the respective structures with zeros before filling them and copying to userspace. - Grow s390 compat_statfs64, statfs and statfs64 structures f_spare array member to cover padding and simplify things. - Remove obsolete SCHED_BOOK and SCHED_DRAWER configs. - Remove unneeded S390_CCW_IOMMU and S390_AP_IOM configs. -----BEGIN PGP SIGNATURE----- iI0EABYIADUWIQQrtrZiYVkVzKQcYivNdxKlNrRb8AUCZGd5BRccYWdvcmRlZXZA bGludXguaWJtLmNvbQAKCRDNdxKlNrRb8OqMAQCsdBG7eR3dp3mY8ao34dqlWt98 rDQD8oiMgCkFyn77jQEAoo3HhqWY8oTu88fl82dkF0OpGW+7zgoNHUYhH8Z0gAY= =wtTO -----END PGP SIGNATURE----- Merge tag 's390-6.4-2' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux Pull s390 fixes from Alexander Gordeev: - Add check whether the required facilities are installed before using the s390-specific ChaCha20 implementation - Key blobs for s390 protected key interface IOCTLs commands PKEY_VERIFYKEY2 and PKEY_VERIFYKEY3 may contain clear key material.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
