1400 Choose this option to build a kernel for release 2 or later of the
1401 MIPS64 architecture. Many modern embedded systems with a 64-bit
1402 MIPS processor are based on a MIPS64 processor. If you know the
1403 specific type of processor in your system, choose those that one
1404 otherwise CPU_MIPS64_R1 is a safe bet for any MIPS64 system.

1416 Choose this option to build a kernel for release 6 or later of the
1417 MIPS64 architecture. New MIPS processors, starting with the Warrior
1418 family, are based on a MIPS64r6 processor. If you own an older

1428 Please make sure to pick the right CPU type. Linux/MIPS is not
1429 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1430 *not* work on R4000 machines and vice versa. However, since most
1431 of the supported machines have an R4000 (or similar) CPU, R4x00
1432 might be a safe bet. If the resulting kernel does not work,
1433 try to recompile with R3000.

2006 The kernel memory allocator divides physically contiguous memory
2007 blocks into "zones", where each zone is a power of two number of
2008 pages. This option selects the largest power of two that the kernel
2009 keeps in the memory allocator. If you need to allocate very large
2010 blocks of physically contiguous memory, then you may need to
2011 increase this value.
2012
2013 This config option is actually maximum order plus one. For example,
2014 a value of 11 means that the largest free memory block is 2^10 pages.
