1803 Loongson 2F03 and later have fixed these issues and no workarounds
1804 are needed. The workarounds have no significant side effect on them
1805 but may decrease the performance of the system so this option should

2888 concerning its effect upon the O32 ABI in userland are still being
2889 worked on. In order to avoid userland becoming dependant upon current
2890 behaviour before the details have been finalised, this option should
2891 be considered experimental and only enabled by those working upon
2892 said details.
