Pull x86 cpu updates from Borislav Petkov: - Print the CPU number at segfault time. The number printed is not always accurate (preemption is enabled at that time) but the print string contains "likely" and after a lot of back'n'forth on this, this was the consensus that was reached. See thread at [1]. - After a *lot* of testing and polishing, finally the clear_user() improvements to inline REP; STOSB by default Link: https://lore.kernel.org/r/5d62c1d0-7425-d5bb-ecb5-1dc3b4d7d245@intel.com [1] * tag 'x86_cpu_for_v6.1_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/mm: Print likely CPU at segfault time x86/clear_user: Make it faster
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.
