This is the rest of the cleanups for si_trapno that reduces it from being a really weird arch special case that is expect to be always present (but isn't) on the architectures that support it to being yet another field in the _sigfault union of struct siginfo. The changes have been reviewed and marinated in linux-next. With the removal of this awkward special case new code (like SIGTRAP TRAP_PERF) that works across architectures should be easier to write and maintain. Eric W.
