Shouldn't that comment be moved below the "---"? ;-) I thought the (10Y ;-) plan was to have no more code under arch/arm/mach-*/?

The SMP code is the main part we never figured out where else to put, so it's typically the only thing we still have for new platforms under arch/arm/. >> Fixes: cde4f86f9249 ("arm: shmobile: Add the R9A06G032 SMP enabler driver") >> Signed-off-by: Arnd Bergmann <arnd@arndb.de> > > Reviewed-by: Geert Uytterhoeven <geert+renesas@glider.be>

Lets work out where the code should live and move it if necessary.
