When we don't want to use non-temporal stores for memset, we set `x86_memset_non_temporal_threshold` to SIZE_MAX. The current code, however, we using `maximum_non_temporal_threshold` as the upper bound which is `SIZE_MAX >> 4` so we ended up with a value of `0`. Fix is to just use `SIZE_MAX` as the upper bound for when setting the tunable. Tested-by: Borislav Petkov (AMD) <bp@alien8.de> Reviewed-by: H.J. Lu <hjl.tools@gmail.com>
