[PATCH] KVM: arm64: Move __hyp_set_vectors out of .hyp.text

[Quentin Perret]

The .hyp.text section is supposed to be reserved for the nVHE EL2 code.
However, there is currently one occurrence of EL1 executing code located
in .hyp.text when calling __hyp_{re}set_vectors(), which happen to sit
next to the EL2 stub vectors. While not a problem yet, such patterns
will cause issues when removing the host kernel from the TCB, so a
cleaner split would be preferable.

Fix this by delimiting the end of the .hyp.text section in hyp-stub.S.
