1502 Please make sure to pick the right CPU type. Linux/MIPS is not
1503 designed to be generic, i.e. Kernels compiled for R3000 CPUs will

1505 of the supported machines have an R4000 (or similar) CPU, R4x00
1506 might be a safe bet. If the resulting kernel does not work,

1738 64-bit addressing which in turn makes the PTEs 64-bit in size.

1754 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1755 require workarounds. Without workarounds the system may hang
1756 unexpectedly. For more information please refer to the gas
1757 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1758
1759 Loongson 2F03 and later have fixed these issues and no workarounds
1760 are needed. The workarounds have no significant side effect on them
1761 but may decrease the performance of the system so this option should
1762 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1763 systems.

2783 running a MIPS32 system and know that none of your userland binaries
