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, we have to handle differences in how GCC's inline optimizations get resolved. For arm64 this requires forcing one function to be inline with __always_inline.
