1194 designed to be generic, i.e. Kernels compiled for R3000 CPUs will

1415 Loongson 2F03 and later have fixed these issues and no workarounds
1416 are needed. The workarounds have no significant side effect on them
1417 but may decrease the performance of the system so this option should
1418 be disabled unless the kernel is intended to be run on 2F01 or 2F02

1724 Virtual SMP uses the processor's VPEs to implement virtual
1725 processors. In currently available configuration of the 34K processor
1726 this allows for a dual processor. Both processors will share the same
1727 primary caches; each will obtain the half of the TLB for it's own
1728 exclusive use. For a layman this model can be described as similar to
1729 what Intel calls Hyperthreading.
