I added the USE_64KB_PAGE_BLOCK build option in bug #217989 for use by RHEL. But going forward, I don't need it anymore, and can maintain it downstream where it is needed. (This option might also be useful to SUSE, but they already don't use it, so won't miss it.) I've seen users who don't understand the consequences of this option enabling it on x86_64, even though there are serious negative consequences and zero benefits to using it. So let's get rid of it.
