Subject: [PATCH v4 3/7] mips: rename macros and files from '64' to 'n64'
When we get nanoMIPS support we'll be introducing the p32
ABI, and there's a reasonable chance that the equivalent
p64 ABI may come along in the future. Using 'n64' now would
avoid confusion in that case where we may have 2 different
64-bit ABIs.
