Hyp keeps track of which cores require SSBD callback by accessing a kernel-proper global variable. Create an nVHE symbol of the same name and copy the value from kernel proper to nVHE as KVM is being enabled on a core. Done in preparation for separating percpu memory owned by kernel proper and nVHE.

Acked-by: Will Deacon <will@kernel.org> Marc: please take a look at for-next/ghostbusters on the arm64 tree, as that has the patches which remove this stuff entirely. I had to rebase the branch today because I screwed up some of the SoBs but the HEAD is now stable at 780c083a8f84.
