If anyone has any objections, please let me know. ------------------ From: Kees Cook [ Upstream commit 6418a8504187dc7f5b6f9d0649c03e362cb0664b ] 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.
