In history.git, I found 51e9e9743877660198565a86034ca72de73dcf7e from
2003 which adds BROKEN_ON_SMP. Commit message says:
- let all drivers that don't compile on SMP (due to cli/sti usage)
depend on a BROKEN_ON_SMP that is only defined if !SMP || BROKEN
But then again, there is also 4b16dac1d9 ("[PATCH] i2c-elektor: get rid
of cli/sti") from 2004 which converts the driver from cli/sti to
spinlocks. Maybe it just works now?
