1197 designed to be generic, i.e. Kernels compiled for R3000 CPUs will

1416 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1417
1418 Loongson 2F03 and later have fixed these issues and no workarounds
1419 are needed. The workarounds have no significant side effect on them
1420 but may decrease the performance of the system so this option should
1421 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1422 systems.

1749 Virtual SMP uses the processor's VPEs to implement virtual
1750 processors. In currently available configuration of the 34K processor
1751 this allows for a dual processor. Both processors will share the same
1752 primary caches; each will obtain the half of the TLB for it's own

1754 what Intel calls Hyperthreading.
