This datum is not referenced from .idmap.text: it does not need to be
mapped in idmap. Lets move it to .rodata as it is never written to
after
early boot of the primary CPU.
(Maybe .data.ro_after_init would be cleaner though?)
Can we move this into arch/arm64/mm/mmu.c, where we already have
kimage_voffset:
| u64 kimage_voffset __ro_after_init;
| EXPORT_SYMBOL(kimage_voffset);
... or is it not possible to initialize kimage_vaddr correctly in C?
Good question... I'll check tomorrow.
