1419 *not* work on R4000 machines and vice versa. However, since most
1420 of the supported machines have an R4000 (or similar) CPU, R4x00
1421 might be a safe bet. If the resulting kernel does not work,
1422 try to recompile with R3000.

1995 The kernel memory allocator divides physically contiguous memory
1996 blocks into "zones", where each zone is a power of two number of
1997 pages. This option selects the largest power of two that the kernel
1998 keeps in the memory allocator. If you need to allocate very large
1999 blocks of physically contiguous memory, then you may need to
2000 increase this value.
2001
2002 This config option is actually maximum order plus one. For example,
2003 a value of 11 means that the largest free memory block is 2^10 pages.

2006 when choosing a value for this option.

2599 32-bit MIPS systems this support is at the cost of increasing the
2600 size and complexity of the compiled FPU emulator. Thus if you are
2601 running a MIPS32 system and know that none of your userland binaries
