- Fix virtual vs physical address confusion in vmem_add_range() and vmem_remove_range() functions. - Include <linux/io.h> instead of <asm/io.h> and <asm-generic/io.h> throughout s390 code. - Make all PSW related defines also available for assembler files. Remove PSW_DEFAULT_KEY define from uapi for that. - When adding an undefined symbol the build still succeeds, but userspace crashes trying to execute VDSO, because the symbol is not resolved. Add undefined symbols check to prevent that. - Use kvmalloc_array() instead of kzalloc() for allocaton of 256k memory when executing s390 crypto adapter IOCTL. - Add -fPIE flag to prevent decompressor misaligned symbol build error with clang. - Use .balign instead of .align everywhere. This is a no-op for s390, but with this there no mix in using .align and .balign anymore. - Filter out -mno-pic-data-is-text-relative flag when compiling kernel to prevent VDSO build error. - Rework entering of DAT-on mode on CPU restart to use PSW_KERNEL_BITS mask directly. - Do not retry administrative requests to some s390 crypto cards, since the firmware assumes replay attacks. - Remove most of the debug code, which is build in when kernel config option CONFIG_ZCRYPT_DEBUG is enabled. - Remove CONFIG_ZCRYPT_MULTIDEVNODES kernel config option and switch off the multiple devices support for the s390 zcrypt device driver. - With the conversion to generic entry machine checks are accounted to the current context instead of irq time. As result, the STCKF instruction at the beginning of the machine check handler and the lowcore member are no longer required, therefore remove it. - Fix various typos found with codespell. - Minor cleanups to CPU-measurement Counter and Sampling Facilities code. - Revert patch that removes VMEM_MAX_PHYS macro, since it causes a regression. -----BEGIN PGP SIGNATURE----- iI0EABYIADUWIQQrtrZiYVkVzKQcYivNdxKlNrRb8AUCZKakSBccYWdvcmRlZXZA bGludXguaWJtLmNvbQAKCRDNdxKlNrRb8HeIAQCg9RX3/olsZhCqRNLZ/O+6FXAF 29ohi2JmVqxJBKkmwgEA/QXCjoTOp41pQJ1FD39HnI8DeYpJFRnYYE5D3acibAw= =2Ykk -----END PGP SIGNATURE----- Merge tag 's390-6.5-2' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux Pull more s390 updates from Alexander Gordeev: - Fix virtual vs physical address confusion in vmem_add_range() and vmem_remove_range() functions - Include <linux/io.h> instead of <asm/io.h> and <asm-generic/io.h> throughout s390 code - Make all PSW related defines also available for assembler files.

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.
