Hats off; this kind of mad genius is the best of what I hope to read on Hacker™ News.

Possible user-space DoS on Linux when running on an ARM7 CPU in just two instructions. Would that be a record? If the kernel was configured to support OABI (exclusively or together with EABI), I think the following two-ARM-instr binary will simply crash the kernel if the core has alignment checking: SUB PC, PC, #2; SWI 0. I am not sure how common such configs are, but someone should maybe fix that? The fix would be only one extra instruction.
