Pull s390 fixes from Vasily Gorbik: - a few ptrace fixes mostly for strace and seccomp_bpf kernel tests findings - cleanup unused pm callbacks in virtio ccw - replace kmalloc + memset with kzalloc in crypto - use $(LD) for vDSO linkage to make clang happy - fix vDSO clock_getres() to preserve the same behaviour as posix_get_hrtimer_res() - fix workqueue cpumask warning when NUMA=n and nr_node_ids=2 - reduce SLSB writes during input processing, improve warnings and cleanup qdio_data usage in qdio - a few fixes to use scnprintf() instead of snprintf() * tag 's390-5.8-2' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: s390: fix syscall_get_error for compat processes s390/qdio: warn about unexpected SLSB states s390/qdio: clean up usage of qdio_data s390/numa: let NODES_SHIFT depend on NEED_MULTIPLE_NODES s390/vdso: fix vDSO clock_getres() s390/vdso: Use $(LD) instead of $(CC) to link vDSO s390/protvirt: use scnprintf() instead of snprintf() s390: use scnprintf() in sys_##_prefix##_##_name##_show s390/crypto: use scnprintf() instead of snprintf() s390/zcrypt: use kzalloc s390/virtio: remove unused pm callbacks s390/qdio: reduce SLSB writes during Input Queue processing selftests/seccomp: s390 shares the syscall and return value register s390/ptrace: fix setting syscall number s390/ptrace: pass invalid syscall numbers to tracing s390/ptrace: return -ENOSYS when invalid syscall is supplied s390/seccomp: pass syscall arguments via seccomp_data s390/qdio: fine-tune SLSB update
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.
