1391 Please make sure to pick the right CPU type. Linux/MIPS is not
1392 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1393 *not* work on R4000 machines and vice versa. However, since most
1394 of the supported machines have an R4000 (or similar) CPU, R4x00
1395 might be a safe bet. If the resulting kernel does not work,

2003 blocks into "zones", where each zone is a power of two number of
2004 pages. This option selects the largest power of two that the kernel
2005 keeps in the memory allocator. If you need to allocate very large
2006 blocks of physically contiguous memory, then you may need to
2007 increase this value.

2009 This config option is actually maximum order plus one. For example,
2010 a value of 11 means that the largest free memory block is 2^10 pages.
