1778 64-bit addressing which in turn makes the PTEs 64-bit in size.

1799 Loongson 2F03 and later have fixed these issues and no workarounds
1800 are needed. The workarounds have no significant side effect on them
1801 but may decrease the performance of the system so this option should
1802 be disabled unless the kernel is intended to be run on 2F01 or 2F02

2252 on cores with the MT ASE and uses the available VPEs to implement
2253 virtual processors which supports SMP. This is equivalent to the

3058 bus while maintaining backward compatibility with cards made for
