I don't think it's safe to use virt_to_page() on static kernel
addresses (text, data, and bss). For example, ia64 linux nowadays
uses a virtual mapping for the static kernel memory, so it's not part
of the identity-mapped segment.
That's correct and it'll break on sparc64 for similar reasons.
It's also not safe to do virt_to_page() on kernel stack addresses
