Yikes - yes! Apologies, I somehow missed that mail back then (in the
middle of two weeks essentially off the grid).
I pushed your patch with some minor changes; see below.

+ The Loongson <code>loongson-mmi</code> and <code>loongson-ext</code>
+ extensions have been split from <code>loongson3a</code>:
+ <ul>
+ <li><code>loongson-mmi</code> contains
+ the Loongson MMI (MultiMedia extensions Instructions).</li>
+ <li><code>loongson-ext</code> contains
+ the Loongson EXT (EXTensions instructions).</li>

+ <li>
+ The Loongson EXT2 (EXTensions R2 instructions) are now supported.
+ <ul>
+ <li><code>loongson-ext2</code> contains the Loongson EXT2
instructions.</li>
+ </ul>
+ Command-line options<code>-m[no-]loongson-mmi</code>,
+ <code>-m[no-]loongson-ext</code>, and <code>-m[no-]loongson-ext2</code>
+ enable or disable those extensions.
+ </li>
+ <li>
+ Support has been added for the following processors
+ (GCC identifiers in parentheses):
+ <ul>
+ <li>Loongson 3A1000 (<code>gs464</code>)
+ which enables <code>loongson-mmi</code>, <code>loongson-ext</code> by
default.</li>
+ <li>Loongson 3A2000/3A3000 (<code>gs464e</code>)
+ which enables <code>loongson-mmi</code>, <code>loongson-ext</code>,
<code>loongson-ext2</code> by default.</li>
+ <li>Loongson 2K1000 (<code>gs264e</code>)
+ which enables <code>loongson-ext</code>, <code>loongson-ext2</code>,
<code>msa</code> by default.</li>
+ </ul>
+ The GCC identifiers can be used as arguments to the <code>-mcpu</code>
+ and <code>-mtune</code> options (as in <code>-mcpu=gs464</code> or
+ <code>-mtune=gs464e</code>) or as arguments to the equivalent target
+ attributes and pragmas.
