1195 designed to be generic, i.e. Kernels compiled for R3000 CPUs will

1414 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1415
1416 Loongson 2F03 and later have fixed these issues and no workarounds
1417 are needed. The workarounds have no significant side effect on them
1418 but may decrease the performance of the system so this option should
1419 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1420 systems.

1725 Virtual SMP uses the processor's VPEs to implement virtual
1726 processors. In currently available configuration of the 34K processor
1727 this allows for a dual processor. Both processors will share the same
1728 primary caches; each will obtain the half of the TLB for it's own
1729 exclusive use. For a layman this model can be described as similar to
1730 what Intel calls Hyperthreading.
