1416 Please make sure to pick the right CPU type. Linux/MIPS is not
1417 designed to be generic, i.e. Kernels compiled for R3000 CPUs will

1995 blocks into "zones", where each zone is a power of two number of
1996 pages. This option selects the largest power of two that the kernel
1997 keeps in the memory allocator. If you need to allocate very large
1998 blocks of physically contiguous memory, then you may need to
1999 increase this value.

2001 This config option is actually maximum order plus one. For example,
2002 a value of 11 means that the largest free memory block is 2^10 pages.

2597 running a MIPS32 system and know that none of your userland binaries
