Even non-KASLR kernels can be built as relocatable, to work around
broken bootloaders that violate the rules regarding physical placement
of the kernel image - in this case, the physical offset modulo 2 MiB is
used as the KASLR offset, and all absolute symbol references are fixed
up in the usual way. This workaround is enabled by default.
CONFIG_RELOCATABLE can also be disabled entirely, in which case the
relocation code and the code that captures the offset are omitted from
the build. However, since commit aacd149b6238 ("arm64: head: avoid
relocating the kernel twice for KASLR"), this code got out of sync, and
we still add the offset to the kernel virtual address before populating
the page tables even though we never capture it. This means we add a
bogus value instead, breaking the boot entirely.
