KVM nVHE code runs under a different VA mapping than the kernel, hence so far it avoided using absolute addressing because the VA in a constant pool is relocated by the linker to a kernel VA (see hyp_symbol_addr). Now the kernel has access to a list of positions that contain a kimg VA but will be accessed only in hyp execution context. These are generated by the gen-hyprel build-time tool and stored in .hyp.reloc. Add early boot pass over the entries and convert the kimg VAs to hyp VAs. Note that this requires for .hyp* ELF sections to be mapped read-write at that point.
