Why is this patch necessary? Presumably there is something further

I could not find it. This write has been in the code since the initial
git history. Is the pre-git bitkeeper tree somewhere available?
I didn't ask why the write was necessary, but why you need it to be
conditional.
I know why the write is necessary: it is (presumably) there to clear the
TSS busy bit.
However, as for older records:
-bk era history (2.5.0-2.6.12-rc2):
git://git.kernel.org/pub/scm/linux/kernel/git/tglx/history.git
Ancient history (pre-2.4.0):
git://git.kernel.org/pub/scm/linux/kernel/git/davej/history.git
There doesn't seem to be any git trees known for the bridge between
2.4.0 and 2.5.0.
