- Add missing Kconfig option for ftrace direct multi sample, so it can be compiled again, and also add s390 support for this sample. - Update Christian Borntraeger's email address. - Various fixes for memory layout setup. Besides other this makes it possible to load shared DCSS segments again. - Fix copy to user space of swapped kdump oldmem. - Remove -mstack-guard and -mstack-size compile options when building vdso binaries. This can happen when CONFIG_VMAP_STACK is disabled and results in broken vdso code which causes more or less random exceptions. Also remove the not needed -nostdlib option. - Fix memory leak on cpu hotplug and return code handling in kexec code. - Wire up futex_waitv system call. - Replace snprintf with sysfs_emit where appropriate. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEECMNfWEw3SLnmiLkZIg7DeRspbsIFAmGZBmIACgkQIg7DeRsp bsLevQ//XfCEcvJ1sB4OEiN97xyy5me4FoOo5rWuzG/ZN/YmUH0CkzJHIhjDcCg3 2FslxH5doOA3zLEBCQKXtcW4uaLSgJcqDgFgpE0TZk/6VKB9RD5q2eSjd+akFMGh HFge54pfgpR7pYYwWRvbqOJRyzkU5oHAjMmt2UweOoX3qwynhMhTrT/03Y9pGMgK VBHhp+ocfdLGQk3nbehAWsh7AWItWwOtKblsTFoyJ6BW0pxb7Yc6+wrpyxLYCaRK rCbyXDStvDqjeBSdx2GZDrA7HbVsrZTHA7sSStIW8yIss1/YJXTP0J2PMXmYNbeE ou2WCg/iti1DNwN7AOR0OdPu1NfPQkyW6NmV8814Haa8Ub3GUc6RCo+U4wlCXAbo ZcHWlb8sgWgfQMzho3WfgkeXuEohO+nOV/x/JFt+NFcwidNTQKO7FQ8GsyylUcYo fBhElbn7p44eS1ivMFEwzptBbpH1JVbb30iV7tMWxyjJQ9TkzpsC3Ph14JimSChk oZuUnmgMztss/ikEMFcDLhd3DNedXfz10Boq6FucD8x46cW5j7o0scwIomcNtxmx C3Y9JCsDdiXAfS6Et6KGbsuWbigT3NjNKETK0+Be65GYNP/NPD5pXLeKywU++cHe e+Lucqiej9polcGN3X97lORMDEx0dXpGkM6ZK2rtX66e7rBbB7M= =n7BA -----END PGP SIGNATURE----- Merge tag 's390-5.16-3' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux Pull s390 updates from Heiko Carstens: - Add missing Kconfig option for ftrace direct multi sample, so it can be compiled again, and also add s390 support for this sample. - Update Christian Borntraeger's email address. - Various fixes for memory layout setup.

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.
