Free up a register in the p2v patching code by switching to relative references, which don't require keeping the phys-to-virt displacement live in a register. Signed-off-by: Ard Biesheuvel <ardb@kernel.org>Neat! Reviewed-by: Linus Walleij <redacted>
Thanks. I just realized, though, that this patch requires the R_ARM_REL32 from [0] as well, as there are a few rare occurrences of phys_to_virt() in module code (musb_hdrc and vivid) [0] https://lore.kernel.org/linux-arm-kernel/20200914095706.3985-4-ardb@kernel.org/ (local) If nobody minds, I will just fold it into the PR, as it has been reviewed and discussed already between Russel, Nico and myself. _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
