The obvious one being that CPU caps aren't set yet. And then there was
this wild goose chase about fixup_pointer() and whether the compiler
generates rip-relative addressing to global vars in early boot code
which runs out of 1:1 mapping and could be loaded somewhere else...

So I'm not opposed to doing cap flags - that would get rid of the new
flags but it needs to be done carefully because with early boot, the
devil's in the detail.

Thx.
