1255 Please make sure to pick the right CPU type. Linux/MIPS is not
1256 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1257 *not* work on R4000 machines and vice versa. However, since most
1258 of the supported machines have an R4000 (or similar) CPU, R4x00
1259 might be a safe bet. If the resulting kernel does not work,
1260 try to recompile with R3000.

1464 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1465 require workarounds. Without workarounds the system may hang
1466 unexpectedly. For more information please refer to the gas
1467 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1468
1469 Loongson 2F03 and later have fixed these issues and no workarounds
1470 are needed. The workarounds have no significant side effect on them
1471 but may decrease the performance of the system so this option should
1472 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1473 systems.
1474
1475 If unsure, please say Y.

1788 The kernel memory allocator divides physically contiguous memory
1789 blocks into "zones", where each zone is a power of two number of
1790 pages. This option selects the largest power of two that the kernel
1791 keeps in the memory allocator. If you need to allocate very large
1792 blocks of physically contiguous memory, then you may need to
1793 increase this value.
1794
1795 This config option is actually maximum order plus one. For example,
1796 a value of 11 means that the largest free memory block is 2^10 pages.
1797
1798 The page size is not necessarily 4KB. Keep this in mind
1799 when choosing a value for this option.
