1401 Choose this option to build a kernel for release 2 or later of the
1402 MIPS64 architecture. Many modern embedded systems with a 64-bit
1403 MIPS processor are based on a MIPS64 processor. If you know the
1404 specific type of processor in your system, choose those that one
1405 otherwise CPU_MIPS64_R1 is a safe bet for any MIPS64 system.

1417 Choose this option to build a kernel for release 6 or later of the
1418 MIPS64 architecture. New MIPS processors, starting with the Warrior
1419 family, are based on a MIPS64r6 processor. If you own an older
1420 processor, you probably need to select MIPS64r1 or MIPS64r2 instead.

1429 Please make sure to pick the right CPU type. Linux/MIPS is not
1430 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1431 *not* work on R4000 machines and vice versa. However, since most
1432 of the supported machines have an R4000 (or similar) CPU, R4x00
1433 might be a safe bet. If the resulting kernel does not work,
1434 try to recompile with R3000.

2007 The kernel memory allocator divides physically contiguous memory
2008 blocks into "zones", where each zone is a power of two number of
2009 pages. This option selects the largest power of two that the kernel
2010 keeps in the memory allocator. If you need to allocate very large
2011 blocks of physically contiguous memory, then you may need to
2012 increase this value.
2013
2014 This config option is actually maximum order plus one. For example,
2015 a value of 11 means that the largest free memory block is 2^10 pages.
