I know that a certain other Linus frequently complains when ARM specific
options show up on his x86 machine during "make oldconfig" ;-)

One idea I had is to create a global CONFIG_SOC option that would
hide all on-chip peripherals when building for a PC-like system.
On ARM, we would always select CONFIG_SOC, except for a few special
cases like ARCH_RPC, ARCH_FOOTBRIDGE and ARCH_SHARK.

Right, I was specifically asking about the technical possibilities,
not what people are likely to do.
