sparc64: Fix race in arch/sparc64/kernel/trampoline.S Make arch/sparc64/kernel/trampoline.S in 2.6.27.1 lock prom_entry_lock when calling the PROM. This prevents a race condition that I observed causing a hang on startup on a 12-CPU E4500. I am not subscribed to this list, so please CC me on replies.
