To split up APEIs in_nmi() path, the caller needs to always be in_nmi(). KVM shouldn't have to know about this, pull the RAS plumbing out into a header file. Currently guest synchronous external aborts are claimed as RAS notifications by handle_guest_sea(), which is hidden in the arch codes mm/fault.c. 32bit gets a dummy declaration in system_misc.h. There is going to be more of this in the future if/when the kernel supports the SError-based firmware-first notification mechanism and/or kernel-first notifications for both synchronous external abort and SError. Each of these will come with some Kconfig symbols and a handful of header files. Create a header file for all this. This patch gives handle_guest_sea() a 'kvm_' prefix, and moves the declarations to kvm_ras.h as preparation for a future patch that moves the ACPI-specific RAS code out of mm/fault.c.

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.
