Did 'Big endian MIPS' refer to 32-bit, or both 32 & 64-bit ? I'm guessing
it was only 32-bit BE, given the heading of your removed-features.txt
change.
But then did "MIPS since 11.0" refer to 64-bit little endian only, or
both big & little endian for 64-bit ?
Given the wide variety of things all ambiguously called "MIPS",
its worth being explicit....

...so if this is 64-bit MIPS, big & little endian, lets say so
