When building ARCH=hexagon allmodconfig, the following errors occur:
ERROR: modpost: "__raw_readsl" [drivers/i3c/master/svc-i3c-master.ko] undefined!
ERROR: modpost: "__raw_writesl" [drivers/i3c/master/dw-i3c-master.ko] undefined!
ERROR: modpost: "__raw_readsl" [drivers/i3c/master/dw-i3c-master.ko] undefined!
ERROR: modpost: "__raw_writesl" [drivers/i3c/master/i3c-master-cdns.ko] undefined!
ERROR: modpost: "__raw_readsl" [drivers/i3c/master/i3c-master-cdns.ko] undefined!
Export these symbols so that modules can use them without any errors.
Fixes: 013bf24c3829 ("Hexagon: Provide basic implementation and/or stubs for I/O routines.")

It would be nice if this could get into 5.14 at some point so that we
can build ARCH=hexagon allmodconfig in our CI.

Ping? Brian, if you do not want to carry this, can you give an ack so
that Andrew can?
Cheers,

Andrew, could you pick this up? Brian gave his ack and we just got a
0day report about this:
https://lore.kernel.org/r/202108041936.52T4sUU6-lkp@intel.com/
If you need me to resend this, I can.
Cheers,
Nathan
