Kees Cook d1b0d93bfc platform/x86: thinkpad_acpi: Handle KCOV __init vs inline mismatches
[ Upstream commit 6418a85041 ]

When KCOV is enabled all functions get instrumented, unless the
__no_sanitize_coverage attribute is used. To prepare for
__no_sanitize_coverage being applied to __init functions[1], we have
to handle differences in how GCC's inline optimizations get resolved.
For thinkpad_acpi routines, this means forcing two functions to be
inline with __always_inline.

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 reStructuredText 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.
