Don't know about the Fedora kernel, but at least in mainline __pa/__va still work as before for i386/x86-64. It's a single add/sub on i386 and on x86-64 similar, but with different ranges for kernel text vs the other kernel memory. The load address is variable now, but still has a default set at compile time in CONFIG. What might have changed when you enable the relocatable kernel is that the ELF addresses in the vmlinux are different. But at runtime there is no difference. -Andi -- Crash-utility mailing list Crash-utility@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/crash-utility
