I wonder what made 0day find this now. I also guess the one mem_map_via_hcall() call site just used the __weak definition so it didn't cause problems if there wasn't a declaration in the header.

I wonder what made 0day find this now. hi Dave, we recently find some unexpected failures for certain bisections, with the fix, such failures are rerun to see whether we can successfully detect bad commits, which i think this resulted in extra but late finding on old commit on mainline. We will keep scan our bisection process to further improve it to reduce this kind late reporting. > > I also guess the one mem_map_via_hcall() call site just used the __weak > definition so it didn't cause problems if there wasn't a declaration in > the header.

The prototype of mem_map_via_hcall() is missing in its header, so add it.
