[PATCH] Add TAINT_USER and ability to set taint flags from userspace
Allow taint flags to be set from userspace by writing to /proc/sys/kernel/tainted, and add a new taint flag, TAINT_USER, to be used when userspace has potentially done something dangerous that might compromise the kernel. This will allow support personnel to ask further questions about what may have caused the user taint flag to have been set. For example, they might examine the logs of the realtime JVM to see if the Java program has used the really silly, stupid, dangerous, and completely-non-portable direct access to physical memory feature which MUST be implemented according to the Real-Time Specification for Java (RTSJ). Sigh. What were those silly people at Sun thinking?
