1253 Please make sure to pick the right CPU type. Linux/MIPS is not
1254 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1255 *not* work on R4000 machines and vice versa. However, since most
1256 of the supported machines have an R4000 (or similar) CPU, R4x00
1257 might be a safe bet. If the resulting kernel does not work,
1258 try to recompile with R3000.

1462 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1463 require workarounds. Without workarounds the system may hang
1464 unexpectedly. For more information please refer to the gas
1465 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1466
1467 Loongson 2F03 and later have fixed these issues and no workarounds
1468 are needed. The workarounds have no significant side effect on them
1469 but may decrease the performance of the system so this option should
1470 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1471 systems.

1473 If unsure, please say Y.

1786 The kernel memory allocator divides physically contiguous memory
1787 blocks into "zones", where each zone is a power of two number of
1788 pages. This option selects the largest power of two that the kernel
1789 keeps in the memory allocator. If you need to allocate very large
1790 blocks of physically contiguous memory, then you may need to
1791 increase this value.
1792
1793 This config option is actually maximum order plus one. For example,
1794 a value of 11 means that the largest free memory block is 2^10 pages.
1795
1796 The page size is not necessarily 4KB. Keep this in mind
1797 when choosing a value for this option.
