Ralf Baechle5e83d432005-10-29 19:32:41 +01001097 byte order. These modes require different kernels and a different

1420 Please make sure to pick the right CPU type. Linux/MIPS is not
1421 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1422 *not* work on R4000 machines and vice versa. However, since most
1423 of the supported machines have an R4000 (or similar) CPU, R4x00
1424 might be a safe bet. If the resulting kernel does not work,
1425 try to recompile with R3000.

1998 The kernel memory allocator divides physically contiguous memory
1999 blocks into "zones", where each zone is a power of two number of
2000 pages. This option selects the largest power of two that the kernel
2001 keeps in the memory allocator. If you need to allocate very large
2002 blocks of physically contiguous memory, then you may need to
2003 increase this value.

2005 This config option is actually maximum order plus one. For example,
2006 a value of 11 means that the largest free memory block is 2^10 pages.
