On x86-64, the difference between virtual addresses in the direct map and the corresponding physical addresses is called PAGE_OFFSET, so we exposed that via an architecture callback and the Linux kernel object finder. However, this doesn't translate to other architectures. Namely, on AArch64, the difference is PAGE_OFFSET - PHYS_OFFSET, and both PAGE_OFFSET and PHYS_OFFSET have varied over time and between configurations. We can remove the architecture callback and avoid version-specific logic by letting the page table tell us the offset. We just need an address in the direct map, which is easy to find since this includes kmalloc and memblock allocations. Signed-off-by: Omar Sandoval <osandov@osandov.com> |
