1831 Loongson 2F03 and later have fixed these issues and no workarounds
1832 are needed. The workarounds have no significant side effect on them
1833 but may decrease the performance of the system so this option should

2153 memory overhead for page tables. For 4k page size, a fourth
2154 level of page tables is added which imposes both a memory
2155 overhead as well as slower TLB fault handling.
