Duplicate symbol 'memory.c#get_reserved_device_memory' (ffff82d080140183 !=3D ffff82d080118b5b) Duplicate symbol 'platform_hypercall.c#__maddr_to_virt' (ffff82d08023a3a2 !=3D ffff82d080167e66) Duplicate symbol 'platform_hypercall.c#__virt_to_maddr' (ffff82d08023a401 !=3D ffff82d080167ec5) Duplicate symbol 'platform_hypercall.c#cpumask_check' (ffff82d08023a489 !=3D ffff82d080167f4d) have been committed, to avoid accidental reintroduction? I note that even sysv format doesn't appear to provide directory information, so we still cant distinguish duplicate static symbols in identically named source files in difference directories, but hopefully that should be very rare. Overall, Reviewed-by: Andrew Cooper , although I haven=92t vetted the symbol.c changes too carefully. ~Andrew
