I strongly oppose removal of a port/support for a certain architecture just because some implementations of it are/were problematic. Adding a warning is fine. Alexander P.S. Demi Marie, please note that oss-security list content guidelines explicitly discourage CC'ing other lists(*), and Xen advisories are already stretching this. In this reply, I am still CC'ing many of what you had CC'ed as I am following up on your specific points relevant to those lists, but in general let's be more careful about this. (*) Because we may then get off-topic follow-ups from there, especially if CC'ing project user lists or high-volume lists like LKML. In this specific case, we're lucky so far.
