To pick up changes from:2d2123bc7c("arm64/sve: Add prctl controls for userspace vector length management")7582e22038("arm64/sve: Backend logic for setting the vector length") That showed a limitation of the regexp used in tools/perf/trace/beauty/prctl_option.sh, that matches only PR_{SET,GET}_, but should match a few more, like PR_MPX_*, PR_CAP_* and the one added by the above commit, PR_SVE_SET_*. This silences this warning when building tools/perf: Warning: Kernel ABI header at 'tools/include/uapi/linux/prctl.h' differs from latest version at 'include/uapi/linux/prctl.h' Support for those extra prctl options should be left for the next merge window tho.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
