Pull RAS updates from Borislav Petkov: - Get rid of a bunch of function pointers used in MCA land in favor of normal functions. This is in preparation of making the MCA code noinstr-aware - When the kernel copies data from user addresses and it encounters a machine check, a SIGBUS is sent to that process. Change this action to either an -EFAULT which is returned to the user or a short write, making the recovery action a lot more user-friendly * tag 'ras_core_for_v5.16_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/mce: Sort mca_config members to get rid of unnecessary padding x86/mce: Get rid of the ->quirk_no_way_out() indirect call x86/mce: Get rid of msr_ops x86/mce: Get rid of machine_check_vector x86/mce: Get rid of the mce_severity function pointer x86/mce: Drop copyin special case for #MC x86/mce: Change to not send SIGBUS error during copy from user
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.
