If Markus is happy with the comments, it's all fine with me, please push (I see
you are listed in MAINTAINERS, so I assume you have push access).

Well, you are able to test it (see commands below) :).  But indeed, I think we
should push this patch, which already improves GDB.  It would be nice to at least
get an idea of the status of the test when ran with gdbserver.  Since access to
this hardware is quite limited, it would be appreciated if you could give it a
quick shot and report the results.

$ make check TESTS="gdb.arch/i386-avx512.exp" RUNTESTFLAGS="--target_board=native-extended-gdbserver"
