Peter Zijlstra 0521e8be21 x86/mm/cpa: Fix set_mce_nospec()
The recent commit fe0937b24f ("x86/mm/cpa: Fold cpa_flush_range() and
cpa_flush_array() into a single cpa_flush() function") accidentally made
the call to make_addr_canonical_again() go away, which breaks
set_mce_nospec().

Re-instate the call to convert the address back into canonical form right
before invoking either CLFLUSH or INVLPG. Rename the function while at it
to be shorter (and less MAGA).

Fixes: fe0937b24f ("x86/mm/cpa: Fold cpa_flush_range() and cpa_flush_array() into a single cpa_flush() function")

README

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.
