[PATCH v2 09/14] mips: Handle KCOV __init vs inline mismatches

[Kees Cook]

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
mips this requires forcing a function to be inline with __always_inline.
