KVM in nVHE mode divides up its VA space into two equal halves, and
picks the half that does not conflict with the HYP ID map to map its
linear region. This worked fine when the kernel's linear map itself was
guaranteed to cover precisely as many bits of VA space, but this was
changed by commit f4693c2716b35d08 ("arm64: mm: extend linear region for
52-bit VA configurations").

Applied to arm64 (for-next/core), thanks!
